Chapter 1: Notice the Light

Chapter Introduction

This chapter is for a grown-up to read with a child. The child can read some of it now too. Take your time. The Rooster's favorite time is morning — read part of it then if you can.

---

It is early.

The sky outside is dark blue.

A small bird sits on a fence and watches.

The first bit of light shows up at the bottom of the sky. Pink. Then gold.

The bird stretches its wings.

Cock-a-doodle-doo.

The sun comes up.

The bird turns its head.

The bird looks at you.

Hi. I am the Rooster. We have met before.

Today we are going to notice the light.

Lesson 1.1: Notice the Light Right Now

Learning Goals

By the end of this lesson, the child will:

• Notice the light around them right now
• Notice how light changes through the day
• Notice that light comes from many places
• Notice that light helps the body know when to wake and when to rest

Key Words

• Notice — to pay close attention to something on purpose.
• Sunrise — when the sun comes up in the morning.
• Midday — the middle of the day. The sun is high.
• Sunset — when the sun goes down in the evening.
• Dim — a little dark.
• Glare — when light is so bright it makes you squint.

Look Around. What Light Do You See Right Now?

Stop for a second.

Look around the room.

Where is the light coming from?

Is the sun shining through a window?

Is there a lamp turned on?

Is the room a little dim?

Is it bright?

You can see the room because of light. Light is what lets your eyes see.

The Rooster wants you to notice it.

Light Changes All Day Long

Light is not the same all day.

In the morning, the sun comes up. The sky gets pink, then gold, then bright. This is sunrise. The world wakes up. You wake up.

By midday, the sun is high in the sky. The light is strong. Shadows are short.

In the late afternoon, the sun starts going lower. Light gets softer. Shadows get longer.

At sunset, the sun goes down. The sky might turn pink and orange and red. The light gets dim.

At night, the world is dark. The moon and stars give a little light, but most light is gone.

Then in the morning, the sun comes up again. And it starts over.

The world has done this every single day for a very, very long time.

Different Kinds of Light

Light does not only come from the sun. Light comes from many places.

• The sun. The biggest light in the whole world. It lights up the entire day.
• Lamps and ceiling lights. Inside lights at home and at school.
• Flashlights. Small lights you can carry.
• Candles. Tiny soft lights. (Always with a grown-up nearby.)
• Screens. Phones, tablets, TVs, and computers all make their own light.
• Campfires and fireplaces. Warm lights. (Always with a grown-up.)
• Stars and the moon. Tiny lights you see at night.

Each kind of light is different.

The sun is strong. A candle is soft. A screen is bright in a tricky way (the Rooster will say more about screens in Lesson 1.3).

Your Body Knows Day From Night

Even when you are not thinking about it, your body knows what time of day it is.

When light comes in the morning, your body says: wake up, get ready, be alert.

When the light gets dim in the evening, your body says: slow down, settle, get sleepy.

When it is dark at night, your body says: sleep.

You did not have to learn this. Your body has known it since you were a baby. Bodies have known this since long, long ago.

This is one reason the Rooster and the Cat are good partners.

The Rooster handles the wake-up part. The Cat handles the sleep part. Together, we cover the whole day.

You can help your body by:

• Opening curtains in the morning when you wake up
• Going outside for a little bit in the morning, even if it is cloudy
• Dimming the lights in the evening when bedtime is getting close
• Sleeping in a dark room (a small night light is fine if you need one)

These are not rules. They are just small things that help your body do what it already wants to do.

Lesson Check

1. What is one new light you noticed in the room around you right now?
2. Can you name the four parts of the day the Rooster talked about?
3. Where does light come from? Name three places.
4. What does your body do when light comes? When light gets dim?

Lesson 1.2: The Most Important Rooster Rule — Never Look at the Sun

Learning Goals

By the end of this lesson, the child will:

• Know the most important Rooster rule: never look directly at the sun, ever — load-bearing
• Understand a small reason why (the inside of your eye does not feel the hurt)
• Know what to do if you see another kid looking at the sun
• Know about eclipse safety with ISO 12312-2 certified glasses
• Know that sun hats and sunglasses are good helpers (cross-walk to Camel)

Key Words

• Sun — the biggest light in the world. Very bright. Very far away.
• Sunglasses — glasses that help protect your eyes from bright sun.
• Sun hat — a hat with a brim that shades your face and eyes.
• Eclipse — when the moon goes in front of the sun for a few minutes.
• Eclipse glasses — special certified glasses that let you watch an eclipse safely.
• Tell a grown-up — what you do when something is not safe.

The Most Important Rule

The Rooster has one rule that is bigger than all the others.

Never look directly at the sun. Ever.

Not in the morning.

Not at midday.

Not at sunset.

Not in summer or winter.

Not when the sun is high.

Not when the sun is low.

Not even for a second.

Not even through your fingers.

Not even when the sun looks dimmer (like through clouds or smoke).

Never.

A Small Reason Why

When the Rooster was small, the Rooster's grown-up taught this rule. Now the Rooster is old, and the Rooster teaches it to every child.

Here is a small reason why:

Your skin has an alarm that tells you when something is hurting it. When you touch something too hot, your hand pulls back. When sun shines on your skin too long, your skin starts to feel hot — your body warns you.

But the inside of your eye does NOT have that alarm.

If the sun hurts the inside of your eye, you would not feel it. There would be no pain to warn you to look away. The hurt could happen, and you would not know.

That is why we never test it. That is why we never even peek.

Eye doctors can help with many things. But the hurt from looking at the sun does not always get better [1].

So we never look. Not even once.

You do not need to look at the sun to enjoy the day. Look at the sky around it. Look at the clouds. Look at the trees the sun lights up. Look at the world the sun is making bright.

Just never directly at the sun.

This is one of the most important rules in the whole Library.

If You See Another Kid Looking at the Sun

Sometimes another kid might look up at the sun without knowing the rule.

Here is what you do:

First, do NOT look up yourself. Do not try to see what they are seeing. Keep looking down or sideways.

Then, say to them: "Don't look at the sun. It can hurt your eyes." You can say it kindly.

Then, tell a trusted grown-up. Tell your parent, your teacher, your camp counselor, or any grown-up who takes care of you.

You do not have to fix it yourself. You just have to:

1. Not look up too
2. Tell the kid to look away
3. Tell a grown-up

A grown-up will know what to do next. They might check if the kid's eyes feel okay. They might call an eye doctor. They will know.

You did the right thing by noticing and telling.

Eclipses

Sometimes the moon passes in front of the sun. The sky gets dimmer for a few minutes. The world gets quieter. This is called an eclipse.

Eclipses are amazing. You might see one or two in your life.

But the rule still holds. Even during an eclipse, you cannot look at the sun with your bare eyes.

Even when the moon is in front of part of the sun, the sun is still bright enough to hurt your eyes.

The only safe way for kids to look at an eclipse is with special certified eclipse glasses. A grown-up will know the right kind — they have a special standard printed on them called ISO 12312-2 [2].

Regular sunglasses are NOT safe for eclipses. Even very dark sunglasses. Even fancy sunglasses. Even two pairs at once. They are not strong enough.

Other safe ways to watch an eclipse:

• Watching it on a TV or screen
• Watching the shadows it makes (a grown-up can make a pinhole projector with you)

If you ever see or hear about an eclipse coming:

• Ask your trusted grown-up if you can watch
• They will get the right glasses or set up a safe way
• Never just look up. Always with the special glasses or a safe way.

Sun Hats, Sunglasses, and Sunscreen

The Camel told you about sun safety. The Rooster agrees with the Camel completely.

For bright sun:

• A sun hat with a brim shades your face and eyes
• Sunglasses help protect your eyes
• Sunscreen protects your skin (the Camel said this)
• Shade during the brightest hours

When sunlight bounces off snow, water, or sand, it gets even brighter. This bright bounce is called glare. Glare can make you squint. A hat and sunglasses help a lot with glare.

The Rooster does not wear sunglasses. The Rooster has special bird-eyes. Human eyes need help. Wear what your grown-ups give you for bright sun.

Lesson 1.3: Notice Light at Night — Screens, Bedtime, and When Eyes Need Help

Learning Goals

By the end of this lesson, the child will:

• Notice that screens make their own light
• Notice that screens at bedtime can make sleep harder
• Notice that dim lights in the evening help the body settle
• Know what to do if an eye gets hurt — when to tell a grown-up, when a grown-up calls 911
• Notice that every body uses light in its own way

Key Words

• Screen — a phone, tablet, TV, or computer that makes its own light.
• Bedtime — the time when you settle for sleep.
• 911 — the number a grown-up calls for a real emergency.
• Eye doctor — a doctor who takes care of eyes.
• Blind — when a person does not see with their eyes.
• Low vision — when a person sees some, but not everything clearly.

Screens Make Light

Phones, tablets, TVs, and computers all make their own light.

Screens are bright. Sometimes very bright.

That is part of what makes screens fun to watch.

But screen light is tricky light.

It is bright like daylight, even at nighttime.

When your eyes see bright light at night, your body might think it is still day. Your body might not get sleepy on time.

Then you might lie in bed wide awake. Or you might have wild dreams. Or you might wake up tired.

The Cat and the Rooster both agree:

• Screens during the day are okay, with rules your grown-ups set
• Screens at bedtime can make sleep harder
• Most families have a rule about putting screens away before bed
• Trust your family's rule

You do not need a screen in your bedroom at night. The Rooster has slept on a fence for thousands of years and never once needed a screen.

Soft Light in the Evening

Bright lights at night can keep your body thinking it is still day. So in the evening, many families turn the lights down a little.

• Some families use lamps instead of overhead lights
• Some families use soft warm light instead of bright white light
• Some families have a night light in the bedroom or hallway

These small things help your body get sleepy.

You can ask your grown-ups what your family's evening light is like. You might be surprised — many families already do this without thinking about it.

This is one of the Rooster's quiet helpers.

When Eyes Get Hurt — What to Do

Sometimes eyes get hurt. Here is what to do.

If you have something small in your eye (like an eyelash, a tiny bit of sand, or dust):

• Try to blink it out
• Do not rub your eye
• If it does not come out, tell a trusted grown-up
• A grown-up will help wash it out with clean water

If your eye was hit by something (like a ball, a hand, or you bumped it):

• Tell a trusted grown-up right away
• A grown-up will look at it and decide what to do

If something splashed in your eye (like soap, cleaner, paint, or anything that is not water):

• Tell a grown-up RIGHT AWAY
• A grown-up will rinse your eye with clean water for a long time (about 15 minutes)
• A grown-up might call 911 — that is the emergency number — if the splash is something strong like cleaner or paint
• This is one of the times a grown-up calls 911 for a real emergency. The 911 helpers will come quickly.

If your eye suddenly hurts a lot, sees strange spots, or sees blurry:

• Tell a trusted grown-up right away
• A grown-up will take you to an eye doctor or call the doctor

Your eyes are precious. Tell a grown-up.

The grown-ups in your life will know what to do. You just have to tell them.

Every Body Uses Light in Its Own Way

The Rooster watches many, many kids.

Some kids see really well.

Some kids need glasses to see clearly. Glasses are tools — like a hat is a tool for the sun. Many kids start wearing glasses around your age. It is normal.

Some kids see colors differently. They might see some greens and reds in a new way. They are not missing anything — they just see the world a little different.

Some kids have low vision — they see some, but not everything clearly. They might use big-print books or a magnifier (a small tool that makes things bigger) to read.

Some kids are blind — they do not see with their eyes. They learn through other senses — hands and ears and smell and balance. Some blind kids read using a touch-language called Braille — bumpy dots their fingers can feel. Some blind kids use white canes to know what is in front of them. Some blind kids have guide dogs — special dogs trained to help them walk safely.

Some kids are very sensitive to light. Bright light bothers their eyes. They might wear sunglasses indoors or like rooms that are dim. This is real and okay.

All of these are good ways to be.

Every body uses light in its own way.

If you meet a kid who uses light differently from you, the Rooster wants you to remember this:

• Don't grab their glasses. Glasses are part of their face.
• Don't grab a white cane. The cane is helping them know what is around them.
• Don't pet a guide dog without asking. The guide dog is working.
• Ask if they want help with something — don't just decide for them.
• Be a friend, not a helper-without-asking.

Every kind of kid belongs in the Rooster's classroom.

End-of-Chapter Activity: A Whole Day of Light Noticing

The Rooster has a small activity for you and your trusted grown-up.

Spend one day noticing the light. Talk about what you see.

Try to notice:

• The light right when you wake up. What color is the sky? Is the sun up yet?
• The light at breakfast time. Is it brighter now?
• The light at midday. How short or long are shadows?
• The light in the late afternoon. Has it started getting softer?
• The light at dinner time. What color is the sky if you look outside?
• The light right before bed. Are the inside lights bright or dim? Are screens still on?

Draw a picture of one part of the day's light — the part that surprised you most. Show your grown-up.

The Rooster is proud of you.

Instructor's Guide

Important: this Instructor's Guide carries load-bearing parent-education work — pediatric eye-safety (AAO guidance, solar retinopathy data, certified ISO 12312-2 eclipse glasses standard), pediatric vision-screening guidance, vision-different inclusion guidance, screen-time guidance for G1 kids (AAP), body-clock and morning-light parent education, the K-12 morning-sunlight-protocol firewall (Huberman-adjacent content) preserved at parent-only level at G1, parent-only crisis resources, and the NEDA non-functional helpline flag.

Pacing recommendations

This G1 Light chapter is the EIGHTH chapter of the G1 cycle and the third chapter in the Rooster's K-12 spiral. Three lessons. Spans five to seven read-aloud-or-shared-reading sessions of ~15-20 minutes each. The chapter is well-suited to morning or daytime reading; one part can be done right at sunset.

• Lesson 1.1 (Notice the Light Right Now): one to two sessions. Notice light around them, light through the day, light from many sources, body's day-night rhythm. Day-and-night twin partnership with the Cat preserved.
• Lesson 1.2 (The Most Important Rooster Rule): two to three sessions. The never-look-at-the-sun rule is LOAD-BEARING — give it real time. G1 adds a small mechanism (no alarm inside the eye) and the NEW bystander-response teaching: what to do if you see another kid looking up at the sun. Eclipse safety with ISO 12312-2 preserved.
• Lesson 1.3 (Notice Light at Night): two sessions. Screens at bedtime cross-walks to the Cat. Evening dim lights. Eye injury response with 911 introduced in body content load-bearing for chemical splashes and severe trauma. Vision-different inclusion deepened.

Approach to reading

If you can read parts of this chapter during natural light transitions (sunrise, midday outdoor time, sunset), do. G1 kids connect more deeply with light content when they can step outside and see what the chapter is describing in real time.

The never-look-at-the-sun rule needs real time and repetition — both for the rule itself and for the new G1 bystander-response teaching. G1 kids are developmentally ready for "what do you do when you see another kid in trouble" framing; this chapter introduces it in the eye-safety context, paralleling the bystander-response teaching at G1 Cold, G1 Hot, and G1 Breath.

Lesson check answers (for grown-up reference)

Lesson 1.1

1. Open-ended. The child names what they see — sun through a window, lamp, ceiling light, screen, etc.
2. Sunrise (morning), midday, sunset (evening), night.
3. Open-ended. Sample three: sun, lamps, screens, candles, flashlights, fires, stars/moon.
4. Light comes → wakes up. Light gets dim → settles, gets sleepy.

Lesson 1.2

1. Never look directly at the sun. Ever.
2. The inside of the eye does not have a pain alarm. The sun could hurt the eye, and you would not feel it happening.
3. (1) Do NOT look up yourself. (2) Tell the kid to look away. (3) Tell a trusted grown-up.
4. Only certified ISO 12312-2 eclipse glasses (or watching on TV, or pinhole projection).
5. Three from: sun hat, sunglasses, sunscreen, shade.

Lesson 1.3

1. Screens make bright tricky light. The body might think it is still day, making sleep harder.
2. Dim lights, lamps instead of overheads, soft warm light, night lights.
3. Tell a grown-up right away. Grown-up will rinse the eye with clean water. (Grown-up may call 911 for strong splashes.)
4. For chemical splashes that are strong (cleaner, paint, etc.); for severe eye trauma; for life-threatening eye emergencies.
5. Open-ended. Sample: glasses, blind kids, low-vision kids, color-difference, light sensitivity all belong.

Chapter review answer key

1. Light.
2. Sunrise, midday, sunset, night.
3. Never look directly at the sun. Ever.
4. The inside of the eye does not have a pain alarm.
5. (1) Don't look up yourself. (2) Tell them to look away. (3) Tell a grown-up.
6. Certified ISO 12312-2 eclipse glasses, or watching on TV, or pinhole projection.
7. Screen light is bright and tricky. The body might think it is still day, making sleep harder.
8. Tell a grown-up right away. Grown-up will rinse with clean water (about 15 minutes for chemical splashes). Grown-up may call 911 for strong splashes.
9. Open-ended. Kids who see well, kids with glasses, kids with low vision, blind kids, color-different kids, light-sensitive kids — every kind belongs.

Pre-Chapter Conversation for Parents

Before reading the chapter together:

• The Rooster. "We are meeting the Rooster again. This time the Rooster wants us to notice the light."
• The most important rule. "There is one rule the Rooster has that is bigger than all the others. It is about the sun. We are going to talk about it carefully."
• Eye safety. "Eyes are precious. The Rooster will teach what to do if something happens to an eye. We'll learn about a few things including a 911 emergency moment."
• Vision-different friends. "Different kids see in different ways. We're going to talk about that too."

Pediatric Eye Safety (Parent Reference — Load-Bearing)

Solar retinopathy — eye damage from looking at the sun — is permanent and can occur in seconds. The retina (back of the eye) does not have pain sensors, so a child does not feel the damage happening; damage may be detected only later as a blurry or dark spot in vision [1]. The American Academy of Ophthalmology firmly recommends that children (and everyone) never look directly at the sun, period.

G1 deepening: The kid-facing body now teaches the simple mechanism — "the inside of your eye does not have an alarm" — at age-appropriate framing. This is a small but real step from K (which just stated the rule). It teaches the child WHY without scaring them.

Eclipse safety is a load-bearing parent topic:

• Only ISO 12312-2 certified solar viewing glasses (typically labeled "eclipse glasses") are safe for direct viewing [2]
• Regular sunglasses are NOT safe — even very dark ones
• Cameras, phones, binoculars, telescopes (without proper solar filters) actually focus the sun's light more intensely than the bare eye and can cause damage in less than a second
• Pinhole projection or watching on a TV broadcast are safe alternatives
• During totality (only in the narrow path of a total eclipse, only at the exact moment of totality), it is briefly safe to look without glasses; everywhere else, including partial eclipses anywhere, glasses or projection are required
• When in doubt — use glasses or do not look

Eye injury response (parent reference at G1 depth):

• Foreign objects: have the child blink; if it does not clear, rinse with clean water and contact pediatrician if persistent
• Chemical splashes: rinse with clean water for 15-20 minutes immediately; call 911 or Poison Control (1-800-222-1222) for strong cleaners, paint thinners, bleach, drain cleaners, or unknown industrial substances; otherwise contact pediatrician same-day
• Trauma (hit, puncture): cover gently, do not press; for severe trauma (puncture wound, vision change, severe pain, anything sharp) call 911; otherwise contact pediatrician immediately
• Sudden vision changes (spots, blurring, loss): contact pediatrician same-day
• Welding or laser flash: call pediatrician same-day

Pediatric Vision Screening (Parent Reference)

The American Academy of Pediatrics Bright Futures recommends vision screening at:

• Newborn period
• 6-12 months
• 1, 2, 3, and 4 years
• Annually from age 5 onward [3]

By Grade 1 (age 6-7), most children have had at least one formal vision screening. If your child has not had one in the past year, this is a good time.

Signs your G1 child may need an eye exam:

• Squinting
• Tilting head to see
• Sitting too close to TV or screens
• Holding books close to face
• Complaining of headaches or tired eyes
• Eye rubbing
• Difficulty with reading or schoolwork visual tasks
• Eyes that don't appear aligned
• Skipping lines or losing place when reading
• Below-grade reading progress

About 25% of school-age US kids in the US wear corrective lenses. Glasses for G1 kids are common and normal.

Vision-Different Inclusion at G1 (Parent Reference)

G1 expands K's vision-different framing with explicit teaching of WHAT TO DO around kids with different vision needs — don't grab glasses, don't grab white canes, don't pet guide dogs without asking, ask before helping. This is the developmental window where kids start interacting with classmates whose bodies work differently from theirs; the chapter teaches respectful interaction.

If your child has classmates or community members who are blind, low-vision, or use adaptive equipment, this chapter creates good language for talking with your child about it.

Screen Time at G1 (Parent Reference)

The American Academy of Pediatrics provides screen-time guidance [4]:

• School-age (6+): consistent limits set by families; emphasis on what is being watched and how it fits into daily life
• For ALL ages: no screens during meals, no screens in bedrooms at bedtime, no screens within 60 minutes of bedtime when possible

For G1 kids specifically:

• Outdoor time and unstructured play remain more important than screen time
• Educational screen content can be helpful in moderation
• Screen-free meal times and screen-free bedrooms are supported by sleep research
• Avoid background TV when possible
• Model the screen behavior you want your child to learn

(Note: the kid-facing body uses general framing — "screens at bedtime can make sleep harder" — rather than specific hour limits, which are family decisions.)

Body Clock and Morning Light (Parent Reference)

Light is the primary signal that sets your child's body clock — what scientists call the circadian rhythm. Bright morning light, especially outdoor sunlight, helps:

• Set the body clock for the day
• Support a regular wake time
• Make nighttime sleep easier
• Stabilize mood through the day

For G1 kids:

• Open curtains in the morning
• Walk outside before school when possible
• Get outdoor time at midday (recess, lunch, breaks)
• Dim lights in the evening for the hour or so before bed
• Dark bedroom for sleep

This is the framework the chapter teaches at G1 register: wake with light, get sleepy with dim, dark at night. No specific minutes or protocols.

Research has long shown that bright morning light helps set the human body clock [6]; outdoor activity in childhood is also associated with healthier eye development [5]. The Library teaches the broad framework appropriate to G1 without prescribing specific protocols.

K-12 Morning-Sunlight Protocol Firewall (Parent Reference — Load-Bearing, preserved from K)

You may encounter adult-marketed practices around morning sunlight — specific protocols prescribing exact minutes of outdoor light at exact times after waking, lux measurements, specific instructions on whether to wear sunglasses, etc. These protocols are NOT appropriate for G1 kids.

At Grade 1, this firewall is held only at the parent level — your child does not need to know about adult-marketed morning-light protocols yet. The Library teaches your child the general framework (open curtains, get outside when you can, especially in the morning, steady wake time, dim evenings, dark bedroom for sleep) without prescribing specific times or measurements.

If anyone in your family follows a specific morning-light protocol, that is your choice as an adult. When your child is older (Grade 5), the Library will explicitly introduce the framework that distinguishes adult-marketed protocols from age-appropriate kid practice. At G1, your child learns the simple framework that is enough for them.

This preserves the four-firewall K-G2 parent-only protocol-firewall pattern:

All four firewalls are explicitly named in the parent Instructor's Guides as not appropriate for K-G2 kids. At Grade 5, the Library makes these firewalls visible to kids in body content. At K-G2, they live entirely at parent level.

Crisis Resources (parent-only at G1)

At G1, the chapter introduces 911 in body content for eye-emergency context (chemical splashes, severe eye trauma). This is the established G1 pattern — 911 begins appearing in body content with strong trusted-grown-up routing across all G1 chapters as the developmentally appropriate moment.

Other crisis resources remain parent-only at K-G2:

• 988 Suicide & Crisis Lifeline — call or text 988 (operational and verified May 2026)
• Crisis Text Line — text HOME to 741741
• SAMHSA National Helpline — 1-800-662-4357
• Poison Control — 1-800-222-1222 (very useful for chemical eye splashes)
• National Alliance for Eating Disorders — (866) 662-1235

The older NEDA helpline number 1-800-931-2237 is NO LONGER WORKING. Use the National Alliance for Eating Disorders number above instead.

What This Chapter Does Not Teach (Full List for Parent Reference)

• Clock cells, ipRGC, or circadian rhythm technical vocabulary (G4/G5 territory)
• Melatonin or sleepy-chemistry technical naming (G4/G5 functional; G6+ technical)
• Specific morning-sunlight protocols (parent-only firewall — load-bearing)
• Blue-light technical wavelength specifics
• Specific lux measurements
• Laser-specific safety detail beyond "never point at eyes" (G3+ deeper)
• Specific welding-light or fireworks safety detail (G3+ territory)
• Specific screen-time hour limits in kid-facing body (parent-only — family choice)
• Seasonal Affective Disorder vocabulary (G4+ territory)
• Cataracts, age-related eye conditions, glaucoma (adult medicine)
• Pandemic-era topics
• Branded protocols or contemporary popularizers

Discussion Prompts

1. What time of day do you love most?
2. What is your favorite light? Sun? Lamp? Candle? Stars?
3. Have you ever seen the sky right when the sun was rising or setting? What colors did you see?
4. Have you ever met someone who is blind, has glasses, uses a magnifier, or uses a guide dog? What did they show you?
5. Have you ever heard about an eclipse? What questions do you have?
6. What is your family's rule about screens at bedtime?
7. What is one thing you can do to help your body wake up in the morning?

Common Kid Questions

1. "What if I look at the sun by accident for a tiny moment?" — One accidental glance probably will not cause damage. But never on purpose. Never to test it. Always look away when you notice you are looking near the sun. Tell a grown-up so they can keep an eye on how your vision is.

2. "Why can I look at the moon?" — The moon does not make its own light. Moonlight is just sunlight bouncing off the moon's surface. The moon is much, much less bright than the sun. It is safe to look at the moon.

3. "What about stars? Lasers?" — Stars are safe to look at — they are very far away and very faint. Lasers are NOT safe to point at eyes — even small ones (like a laser pointer) can hurt eyes quickly. The Lion and the Rooster both say: never point a laser at anyone's eyes, including your own [7].

4. "What is an eye doctor called?" — There are two main kinds. An optometrist checks your vision and gives glasses. An ophthalmologist is a doctor who does eye surgery and treats eye conditions. Your family's pediatrician can refer you if needed.

5. "Why does my screen make my eyes feel funny?" — Looking at screens up close for a long time can make eyes tired (sometimes people call this "screen fatigue"). Take breaks. Look at something far away every once in a while. If your eyes feel really tired or hurt, tell a grown-up.

6. "What about kids who are blind?" — Blind kids do everything sighted kids do — they just do it differently. They go to school. They have friends. They play. They use their hands, ears, and other senses to know the world. Some use guide dogs. Some use white canes. They are kids who use light in their own way (or through other senses entirely).

7. "What does my eye look like inside?" — The inside of your eye is like a camera. Light comes in through the front. The back of your eye (the retina) catches the picture. Your brain reads the picture. There are lots of tiny working parts — but you don't need to know them all in Grade 1.

8. "What does my body do during an eclipse?" — Just what it usually does. The few minutes of dimmer light during an eclipse is too short to confuse your body clock. The main thing during an eclipse is the eye safety rule — only look with certified ISO 12312-2 glasses.

Family Activity Suggestions

• A morning-light moment. Each morning, open the curtains together. Take a moment to look at the sky. Even on cloudy days, the outdoor light helps the body clock.
• A daily eye check-in. "How are your eyes today?" Builds awareness and language for eye health.
• A sunset watch. Find your local sunset time. Watch the sky together (never directly at the sun) as it changes colors.
• Pinhole projector. Make a simple pinhole projector together (lots of kid-friendly DIY videos available) so the child can experience light projection. Great before an eclipse.
• Glasses respect ritual. If your child or any family member wears glasses, treat them with respect. Always put them in cases. Never grab them. Practice "glasses are tools" framing.
• A "no screens before bed" routine. Even if your family screen-time rules are flexible, the hour before bed is the most important to protect.
• A bystander practice conversation. Role-play with your child: "What would you do if you saw a kid looking up at the sun?" Three steps: don't look up yourself, tell the kid to look away, tell a grown-up.

Founder Review Notes — Safety-Critical Content Protocol

This chapter is flagged founder_review_required: true because it covers safety-critical content categories:

• Age-appropriate health messaging. Picture-book pacing with slight density increase from K. No technical light vocabulary. No clinical eye conditions in body. Calibrated for G1 read-aloud-and-shared-reading.
• Eye safety (LOAD-BEARING). The never-look-at-the-sun rule is the chapter's most important safety teaching, deepened from K with the mechanism ("no alarm inside the eye") and the new bystander-response teaching. Solar retinopathy parent reference. Eclipse safety with ISO 12312-2 standard. Eye injury response guidance including 911 introduction.
• Screen time (light-touch at G1). General framing of "screens at bedtime can make sleep harder" in body content; specific hour-limit guidance (AAP) in parent-only Instructor's Guide.
• Body image vigilance. No comparison framing. No weight discussion. No fear-based framing.
• Vision inclusion (load-bearing). Blind kids, low-vision kids, kids with glasses, light-sensitive kids, color-different kids all explicitly normalized in body content. Cross-walks to Braille, white canes, guide dogs, magnifiers. G1 ADDS "what to do around kids who use light differently" — respectful interaction teaching.
• Ability inclusion. Diverse light-handling scenes throughout.
• Crisis resources — 911 introduced in body content for eye-emergency context. Other crisis resources in parent-only Instructor's Guide. NEDA non-functional flag preserved.
• Parent education (load-bearing). This Guide handles pediatric eye safety, vision screening, vision-different inclusion at G1 depth, screen-time guidance, body-clock education, and the K-12 morning-sunlight-protocol firewall at parent-only level (load-bearing, preserved from K).

Cycle Position Notes

EIGHTH chapter of the G1 cycle. Fourth of the G1 environmental-coach arc. Third chapter in the Rooster's K-12 spiral. Day-and-night twin partnership with the Cat preserved at G1 register. G1 cycle closes with G1 Water (Elephant) — the final G1 chapter, closing the G1 cycle the same way K closed.

Parent Communication Template (send home before reading)

Dear families,

This week our classroom is meeting the Rooster again — for the third time. The chapter is called Notice the Light and it is the eighth chapter of our Grade 1 cycle.

The Rooster deepens what your child learned in Kindergarten: how to notice the light around them, how light changes through the day, how the body uses light, and the most important Rooster rule — never look directly at the sun.

The chapter's load-bearing safety teaching is the never-look-at-the-sun rule — kids never look directly at the sun, ever. Grade 1 adds a small but important step: a simple mechanism ("the inside of your eye does not have a pain alarm") and a new bystander-response teaching (what to do if you see another kid looking up at the sun: don't look up yourself, tell the kid to look away, tell a trusted grown-up).

The chapter also covers:

• Eclipse safety (only certified ISO 12312-2 eclipse glasses are safe; regular sunglasses are NOT safe)
• Sun safety review (cross-walk to the Camel chapter)
• Screens at bedtime making sleep harder (light-touch; family screen-time rules apply)
• What to do when eyes get hurt — including when a grown-up may call 911 for chemical splashes or severe eye trauma
• Vision-different inclusion (blind kids, low-vision kids, kids with glasses, color-different kids, light-sensitive kids — all kids belong, and how to interact respectfully)

The chapter does NOT teach specific morning-sunlight protocols. The Library's editorial position is that adult-marketed morning-sunlight protocols are not appropriate for K-G2 kids. The general framework (open curtains, get outside when you can — especially morning; dim evenings; dark bedroom for sleep) is what fits at this age.

At home, you can:

• Read the chapter (especially in the morning if you can)
• Reinforce the never-look-at-the-sun rule
• Practice the bystander-response three-step (don't look up, tell kid to look away, tell a grown-up)
• Open curtains together in the morning
• Practice family screen-time rules calmly
• Schedule vision screening if not done recently (AAP recommends annually from age 5)

Pediatric guidance for eye safety, vision screening, vision-different inclusion, and screen time is in the full Instructor's Guide.

Thank you for reading the Library with your child.

Illustration Briefs

Chapter Introduction

• Rooster at dawn (G1). Pre-dawn scene. The Rooster on a wooden fence, alert and ready. Sky going from dark blue to pink-gold-orange. A child slightly older than the K version stands in pajamas on a porch, eyes bright with curiosity, ready to notice. Mood: hopeful, alert, awake-and-ready.

Lesson 1.1

• Look around. Where is your light? Three small panels showing the same kid in different rooms — one with sunlight streaming through a window, one with a lamp glowing in a darker corner, one outside in midday sun. In each, the kid is pausing, looking around. The Rooster watches kindly. Caption: "Look around. Where is your light?"
• Day-to-night timeline. Horizontal timeline: sunrise (pink-gold sky, Rooster crowing on fence) → midday (bright sun overhead, kid playing outside) → sunset (orange-red sky, family at outdoor dinner) → night (dark sky with stars and moon, kid in bed with Cat) → dawn (back to pink-gold, Rooster ready again). Caption: "Morning, midday, sunset, night. Over and over."
• Light is everywhere. Multi-panel diverse light sources: sunny outdoor scene, kitchen with overhead lights on, kid with flashlight under a blanket, birthday candle on a small cake, tablet glowing, fireplace with family nearby, night sky with stars and moon. Each labeled. The Rooster in the center. Caption: "Light is everywhere. Each kind is different."
• Wake with light, sleepy with dim. Two-panel split: morning — child stretching as light streams through curtain, Rooster outside window crowing; evening — same child curling up in bed as the room dims and a small night light glows, Cat on bed. Caption: "Your body wakes with light. Your body gets sleepy with dim."

Lesson 1.2

• Never look at the sun (LOAD-BEARING). Sunny day. Child outside in sun hat and sunglasses, looking ahead — NOT up at sun. Sun in upper corner with friendly "look away" curved arrow. The Rooster beside child, also facing forward. Caption: "Never look directly at the sun. Ever."
• Bystander-response (NEW G1). Two kids in a park. One kid is looking up at the sun. The other kid (the reader's stand-in) is looking sideways at them with concern, NOT looking up. The reader-kid is gesturing toward a trusted grown-up nearby and saying "Don't look up." The Rooster is in the background, calm and steady. Caption: "Don't look up yourself. Tell them to look away. Tell a grown-up."
• Eclipse safety. A family scene watching an eclipse safely — wearing ISO-certified eclipse glasses (label clearly visible on the side). A trusted grown-up helping a child put glasses on. Another child watches a pinhole projector make a small image of the eclipse on the ground. The Rooster nearby with the same kind of glasses on. Caption: "Only certified eclipse glasses (ISO 12312-2). Regular sunglasses are NOT safe."
• Sun helpers. Diverse group of kids outside in bright sun — wearing sun hats and sunglasses at the beach, in the snow, and at a park. Some kids in shade under a tree. Sunscreen visible on a towel. The Rooster watching, content. Caption: "Hat. Sunglasses. Sunscreen. Shade."

Lesson 1.3

• Screens at bedtime. Two-panel: left — child happily using tablet in afternoon with grown-up nearby in good lighting; right — same child in bed at bedtime, screen put away on a shelf, reading paper book under soft warm lamplight. Cat curled on bed. Rooster visible at window settling. Caption: "Screens during the day, okay. Screens at bedtime, harder."
• Eye injury response. Two-panel: left — a trusted grown-up gently helping a child rinse an eye at a kitchen sink with cool clean water (both calm); right — a grown-up on a phone calling for help while another grown-up rinses an eye for a stronger splash. The Rooster in the background, steady. Caption: "Tell a grown-up. They will help. For big eye emergencies, a grown-up may call 911."
• Every body uses light in its own way (G1). A diverse group of kids together at school or playground. One in bright sun, one with glasses reading, one with a white cane and friendly guide dog walking confidently with hand on a wall, one reading Braille with fingers, one wearing tinted sunglasses indoors at the edge of the scene, one using a small magnifier on a book. All look content and confident, interacting kindly. The Rooster in the background, eyes soft. Caption: "Every body uses light in its own way. Every kid belongs."

Activity / Closing

• A whole day of light noticing. Child and trusted grown-up at various moments of the day — opening curtains in the morning, walking outside at midday, watching a sunset, sitting under a lamp in the evening. The Rooster visible somewhere in each — perched on a fence, watching from a tree, content in soft evening light. Caption: "Notice the light through your whole day."

Aspect ratios: 16:9 digital, 4:3 print. Diverse skin tones, body sizes, hair textures, gender expressions, abilities (including blind kids with white canes / guide dogs, kids with glasses, low-vision kids with magnifiers, light-sensitive kids with tinted glasses, kids with adaptive equipment), and family compositions throughout. The Rooster's character design is consistent with K Light (and forward to G2-G5 Light).
