Lesson plan

Heat Convection

Visualize heat convection, then make a device that turns with the convection heat from a small candle.
Science content
Physics: Heat (3)

Demonstrate that heat moves upwards in a fluid such as water with the Heat convection demonstration.
Use heat convection to make a candle pinwheel that gracefully turns with the heat from a candle.

If time, demonstrate that the candle needs air to burn by putting jars over it - see candle combustion
