Conduction, Convection and Radiation
Outcomes
- Pupils understand that thermal energy is always transferred from a hotter body to a cooler body/environment.
- Pupils can describe transfers of thermal energy by conduction, convection and radiation.
Specification References
Starter
- Cook popcorn in two ways: with microwave radiation and in a pan by conduction. Probably best not to eat it.
Main Body of Lesson
- Ask pupils why the popcorn popped. There are some great slow motion videos you can show.
- Elicit the idea that the popcorn heated up - why?
- Move pupils towards the idea that thermal energy is transferred from hotter objects to colder ones.
