Heat Transfer in Nature: common misconceptions
See the tempting mistake students make in Heat Transfer in Nature, why it feels right at first glance, and a worked visual example that shows the right idea.

Worked example
Heater ↑ ↑ ↑ Warm air → → Radiation Warm air rises above the heater. Radiation can reach a person at its side. Warm air above a radiant heater rises. From a safe position beside it, you can also feel energy arriving directly as radiation. If your child says… (6 concept checks in this chapter)

If your child says…
“Hot metal travels up the spoon.”
