Build Your Own Mini Solar Oven
Transform a pizza box into a mini solar oven using simple materials. This fun STEM activity allows kids to learn about solar energy while crafting and cooking a delicious treat like s'mores!
Safety notes
No special safety concerns. Ensure children use scissors safely and supervise them during the activity.
What you will need
- Pizza box
- aluminum foil
- plastic wrap
- black construction paper
- tape
- scissors
- marshmallows
- chocolate
- graham crackers
Step-by-step instructions
- Prepare the Pizza Box: Open the pizza box and use scissors to cut a flap in the lid, leaving about an inch around the edges.
- Add Reflective Layer: Cover the underside of the flap with aluminum foil, ensuring it’s smooth and shiny to reflect sunlight effectively.
- Create the Cooking Surface: Place black construction paper inside the pizza box to help absorb heat and enhance cooking efficiency.
- Seal the Box: Cover the opening with plastic wrap, sealing it tightly to keep the heat inside for optimal cooking conditions.
- Prepare Your Treats: Place marshmallows and chocolate on graham crackers, then arrange them neatly inside the box for cooking.
- Position Your Oven: Set the box in a sunny spot, adjusting the flap to reflect sunlight directly into the box for maximum heat absorption.
- Wait and Watch: Observe the treats as they warm up, waiting about 30-60 minutes until they’re melted and gooey.
- Enjoy Your Creation: Carefully open the box, assemble your s'mores, and savor the delicious results of your solar cooking experiment!
