HOW DOES A SOLAR OVEN WORK

A solar oven uses energy from the sun to heat and cook food. How does a solar oven work? The simple answer is that it absorbs more heat than it releases.

Our DIY solar oven below is made out of a pizza box, aluminum foil, plastic wrap, and a sheet of black paper.

The aluminum foil is used to reflect sunlight into the box.

The plastic wrap covers an opening in the box and works like a greenhouse, allowing sunlight to pass into the box, while also keeping the heat in.

At the bottom of the box, you have a black construction paper. This will absorb sunlight and increase the temperature of your DIY solar cooker.

Now make up some yummy s’ mores to cook in your new solar oven!  Read on for the full instructions.

DIY SOLAR OVEN

YOU WILL NEED:

  • S’mores ingredients (marshmallows, Hershey’s bars and graham crackers)
  • Cardboard pizza box
  • Black construction paper
  • Aluminum foil
  • Plastic wrap
  • Wooden skewer
  • Hot glue/hot glue gun
  • Scissors
  • Ruler
  • Sharpie

HOW TO MAKE A SOLAR OVEN

STEP 1. Trace your ruler around the top edges of the box to leave a even square and carefully cut out the top.


STEP 2. Wrap the cardboard square in foil and glue the edges to secure.


STEP 3. Open the box and glue the black construction paper to the bottom of the box.


STEP 4. On the inside on the lid, carefully glue a piece of plastic wrap over the opening.


STEP 5. Time to make your s’mores! Place four graham crackers down on the black paper, 3 chocolate squares and a marshmallows on top of each one.


STEP 6. Carefully close the plastic lid of the box and glue one side of the foil-wrapped cardboard on the top back of the box.

STEP 7. Glue a skewer on the top left corner of the foil-wrapped cardboard and place the other end through the plastic wrap to hold the foil-wrapped cardboard in place.


STEP 8. Place your DIY solar oven in the sun and wait 60 minutes to watch your marshmallows and chocolate melt.
