This Thermal Energy Flow in Materials lesson plan also includes:
The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth lesson in the 10-part series looks at how light energy from the sun transfers into thermal energy. Scholars build a solar oven as well as observe convection in liquids and conduction in solids—all through hands-on activities and experiments.
- Extend the solar oven by predicting how long it would take to reheat a piece of pizza; what variables would one need to know to make a prediction? i.e. thickness, toppings, cloud cover, etc.
- Requires a lot of advanced preparation and construction of materials, which is time consuming
- Be aware of any allergies when using food items
- Remember to follow all safety guidelines with hot items
- Highly visual lesson demonstrates the movement of thermal energy, which typically isn't observable
- Includes two optional extension ideas
- Offers teacher tips for setting up experiments to get the best results
