Build a DIY Solar Oven
Transform a pizza box into a solar oven and harness the power of the sun to cook s'mores! This fun STEM activity teaches kids about solar energy while enjoying a tasty treat together.
Safety notes
No special safety concerns. Ensure children are supervised when using scissors.
What you will need
- 1 pizza box
- aluminum foil
- plastic wrap
- black construction paper
- scissors
- tape
- s'mores ingredients
Step-by-step instructions
- Prepare the Pizza Box: Open the pizza box and lay it flat. Use scissors to cut a flap on the lid about 3/4 of the way through, leaving one edge attached to create a hinge.
- Line with Foil: Cover the underside of the flap and the bottom of the pizza box with aluminum foil, shiny side up, to reflect sunlight effectively.
- Add Black Paper: Place black construction paper inside the bottom of the box to absorb heat, which helps cook the s'mores more efficiently.
- Seal with Plastic Wrap: Cover the opening of the pizza box with plastic wrap, sealing it tightly to trap heat inside and create a greenhouse effect.
- Set Up in Sunlight: Place your solar oven in a sunny spot, adjusting the flap to reflect sunlight inside. Use tape to secure the flap in place if needed.
- Prepare S'mores: As the solar oven heats up, prepare your s'mores by layering chocolate and marshmallows between graham crackers.
- Cook and Enjoy: Check your s'mores after about 30-40 minutes. Once they’re melted, enjoy your delicious treat together and discuss what you learned about solar energy!
Parent guide
Parents should assist with cutting the pizza box and ensure that the solar oven is positioned correctly in direct sunlight. Encourage children to observe the cooking process, ask questions about solar energy, and discuss how the sun's heat is being used to cook the s'mores.
Educational benefits
- Teaches principles of solar energy and heat absorption
- Enhances teamwork and communication skills
- Encourages scientific inquiry and experimentation
Why this works as a screen-time alternative
This engaging activity replaces screen time by allowing families to explore science hands-on and enjoy quality time together while waiting for their tasty s'mores to cook.
Frequently asked questions
How long will it take to cook the s'mores?
It typically takes about 30-40 minutes in direct sunlight for the s'mores to melt and cook.
Can I use other types of food?
Yes! You can experiment with different foods that melt or cook, just ensure they fit inside the pizza box and are safe to eat after cooking.
What if it's cloudy?
The solar oven works best in full sunlight, but you can still try it on a partly cloudy day, just expect longer cooking times.
