Check out our DIY solar oven! And yes, you're seeing that right - S'MORES! We built this awesome solar oven with just a few materials we found hanging around daycare like tape, glue, foil, black construction paper, plastic wrap, and a pizza box!
Here's the Science Behind It:
Solar Radiation: The sun emits electromagnetic radiation, including visible light and infrared radiation (heat).
Reflection: The aluminum foil lining the inside of the pizza box flap reflects the sunlight, concentrating it into the box.
Absorption: The black paper, placed at the bottom of the box, absorbs the sunlight and converts it into thermal energy.
Heat Trapping (Greenhouse Effect): The plastic wrap creates a transparent barrier that allows sunlight to enter but traps the heat inside, preventing it from escaping. This is similar to how a greenhouse works.
Thermal Energy: The trapped heat increases the temperature inside the box, allowing food to cook.
What would you try cooking in this oven? The kids had some fun suggestions!
