Section E — Coach Cold — Why Cold Matters
This section covers Chapter 1, Lessons 1.1 through 1.4.
Part A — Vocabulary (20 points, 2 points each)
Select the best answer for each question.
1. Temperature is:
A) The number of clothes you are wearing B) A measurement of how warm or cold something is — how fast molecules are moving inside it C) The same as wind speed D) Only a measure of how something feels
2. Heat is:
A) The same as temperature B) Energy in the form of motion of molecules — it can move from a warmer object to a cooler one C) Always dangerous D) A type of light
3. Thermoreceptors are:
A) Special cells in your skin and other tissues that detect temperature B) Pieces of clothing C) Tools used by doctors D) Light receptors only
4. Vasoconstriction is:
A) When blood vessels open wider B) When small blood vessels — especially near the skin — narrow to reduce heat loss C) A bone in the leg D) A type of muscle
5. Shivering is:
A) Pretending to be cold B) Rapid small muscle contractions that generate heat to help warm the body C) A sign of fever D) The same as goosebumps
6. Goosebumps are:
A) A skin reaction in which tiny muscles pull body hairs up — useful in furry animals to trap warm air; in humans, mostly a leftover from our ancestors B) A type of allergy C) Found only in birds D) A type of bone
7. Hypothermia is:
A) A normal feeling of being a bit chilly B) A dangerous drop in core body temperature below the normal range — a medical emergency C) A type of food D) An exercise routine
8. Frostbite is:
A) A bug bite that itches in winter B) Tissue damage from freezing, usually in fingers, toes, ears, or nose C) A type of bread D) The same as a sunburn
9. Wind chill is:
A) The temperature inside your house B) A measure of how cold the air feels to exposed skin, factoring in both air temperature and wind speed C) Only used in summer D) The same as humidity
10. Core body temperature is:
A) The temperature of your fingertips B) The temperature deep inside your body, near your vital organs — normally about 98.6°F (37°C) in humans C) The temperature of the room D) The temperature of your hair
Part B — Concept Comprehension (20 points, 2 points each)
Select the best answer for each question.
11. When your skin gets cold, the first thing your body does is usually:
A) Stop breathing B) Tighten the blood vessels near the skin to keep warm blood near the core C) Make you sweat D) Make you fall asleep
12. Your body shivers because:
A) You are weak B) Rapid muscle contractions produce heat, helping warm the body C) Your muscles are out of fuel D) Cold makes you bigger
13. A normal human core temperature is about:
A) 60°F (15°C) B) 98.6°F (37°C) C) 110°F (43°C) D) 0°F (-18°C)
14. Hypothermia begins to set in when core temperature drops below about:
A) 95°F (35°C) B) 70°F (21°C) C) 32°F (0°C) D) Hypothermia is not a real condition
15. Warning signs of hypothermia include:
A) Strong shivering at first, then sometimes confusion, slurred speech, slowed movement, and even a strange feeling of being "warm" as it gets worse B) Only being happy and energetic C) Only sweating heavily D) Only fast running
16. A windy day at 20°F feels much colder than a still day at 20°F because:
A) Wind heats the air B) Wind blows away the thin layer of warm air your body has built up against your skin, making heat loss faster C) The wind blows the temperature higher D) Wind has no effect on cold
17. Humans have lived in cold parts of the world for thousands of years using which tools?
A) Air conditioning only B) Clothing, fire, shelter, and the body's own thermoregulation (shivering, vasoconstriction, body fat) C) Magic D) None — humans only just learned how to handle cold
18. Coach Cold at Grade 6 does not teach:
A) Hypothermia warning signs B) The physics of temperature and heat C) Cold-water immersion protocols (specific times and temperatures for kids to do) D) What thermoreceptors do
19. At your age, the most important cold skill is:
A) Pushing through cold no matter what B) Recognizing when cold is becoming dangerous so you can act — tell a trusted adult, change clothes, get warm C) Avoiding all cold D) Comparing yourself to a polar bear
20. Coach Cold's main message is:
A) Cold is the enemy B) First understand what cold does to your body, then — slowly and safely, with older bodies and adults around — you may learn what to do with it C) Always avoid cold weather D) Take cold showers every day starting now
Part C — Application (30 points, 6 points each)
Write 2-3 complete sentences for each question.
21. Describe what vasoconstriction is and why your body does it when you get cold. What is the body trying to protect?
22. Safety recognition. A friend has been outside playing in the snow for two hours and is now shivering hard, confused about where their phone is, and saying they actually feel "warm." Based on what Lesson 1.4 taught about hypothermia warning signs, what should you do? Be specific.
23. The air temperature outside is 25°F (-4°C) with a strong wind. Your friend wants to go for a run in shorts and a t-shirt. Explain why wind chill matters here and what you would say.
24. Coach Cold says humans are not polar bears but our bodies have built-in cold tools. Describe two of those tools (other than shivering) that the chapter introduced.
25. Coach Cold deliberately does not teach you a "cold protocol" or have you take cold showers at your age. Why not? Use language from the chapter introduction.
