Summary Visualize heat convection, then make a device that turns with the convection heat from a small candle. Science content Physics: Heat (3) Activities in this lesson Heat convection demonstration Candle convection pinwheel Candle chemistry (wax combustion) Procedure 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 Grades taught Gr 2 Gr 3 Gr 4
