Disclosure: we didn’t have to test this class. But we will do it in the future!
Students will make a boat move using a candle (Thermal Energy). The concept of converting potential energy (candle) and fire to kinetic energy (movement of the boat) can be reviewed here as well. This concept is very similar to the idea of steamboats. This activity may be a bit advanced as it requires coiling copper tubes. Make sure you have the equipment to do this. Teachers may decide to teach the concept of pulsed motorboats.
Inquiry Question: Can we make this boat run faster? Answer: Increase the amount of thermal energy by adding candles.
Students can revise to see how they can make the candle boat run faster. Answer: Increase the amount of thermal energy by adding candles. Generally, this is achieved by either using thicker copper tubbing or more tea candles.
