📋 What it is
Heat science is everywhere — cooking, fridges, engines, clothing, weather and keeping your body at 37 °C.
🗣️ Coach says
Once you know heat, daily life makes sense: cooking is controlled heat transfer, a fridge pumps heat OUT to stay cold, engines turn heat into motion, insulation keeps homes comfy, and your own body constantly balances heat to hold ~37 °C. Heat is one of the most useful ideas in science.

Heat explains cooking, fridges, engines, clothing, weather, and your steady body temperature.

What did sublimation say to melting?
"I skip the liquid phase entirely — I'm just that cool... and then hot!"
😲 Whoa!
Your body is a walking heater — it gives off roughly the same heat as a 100-watt light bulb, which is why a crowded room warms up fast.
✅ Quick check: How does a fridge keep food cold?
Say your answer out loud first — then reveal.
It pumps heat OUT of the inside to the outside — moving heat away rather than making "cold".
A fridge transfers heat out; "cold" is just heat removed.
🧪 Try it! (2 minutes)
Feel the warm coils/vent on the back or bottom of a fridge — that’s the heat it removed from inside.
