Have any pizza boxes laying around? Put them to use and create your own oven for s’mores and more!

Take advantage of the hot weather and take your baking outdoors! This easy science experiment can be educational, fun and rewarding for your kiddos.


  • Cardboard pizza box: If you are super crafty, you can make your box from scratch!
  • Black construction paper
  • Aluminum foil
  • Plastic wrap
  • Tape
  • Glue
  • Scissors
  • Pencil: Or something to hold open the “oven door”
  • S’mores supplies: chocolate, marshmallows and graham crackers!


  1. You will want to cut the oven door. The size will depend on how much space you need!

2. Next, you can decorate your solar ovens! If you’d like, of course.

3. Afterwards, you will want to glue down the black construction paper to the bottom of your oven.

4. Once that is complete, glue the aluminum foil to the inside of the oven door so that it can reflect the sun to where you need it to.

5. You are almost done! Don’t forget to tape down the plastic wrap to the opening. This will help keep the heat inside of the oven!

6. Add your s’mores materials and you are ready to go! Use a pencil or something similar to help hold the aluminum foil in an optimal angle.

Below are some STEM learning points that you can go over with your kids to help them understand why each step of building is important to the overall function of the oven!

  • Using sun and a source of heat
  • The purpose of the aluminum foil
  • The purpose of the plastic wrap
  • What would happen if you used different colored construction paper?
  • Will cloudy days melt your s’mores as fast as sunny days? Why or why not?
