Solar Oven

Have you ever wondered if you can cook an egg on the pavement on a hot summer day? Did you know that the sun can provide solar power to energize things like lights in our houses? In this fun experiment, you will get to build an oven with things you can find around your home and our dependable sun! And you’ll get to cook your very own cheese quesadillas. 

Activity Instructions

for Observers (Pre-K through 2nd Grade) or Explorers (3rd Grade through 5th Grade)


What you’ll need:

  • An adult to help you

  • Empty pizza box

  • Marker

  • Ruler

  • Scissors

  • Glue stick

  • Black construction paper

  • Aluminum foil

  • Craft knife (like an Exacto knife or Box cutter)

  • Bamboo skewer, stick or dowel

  • Clear plastic wrap

  • Flour tortilla (or any tortilla wrap of your choice)

  • Shredded cheese 



Here's a video, or follow the instructions below. 

  • Using your ruler and a pencil, measure a window with a 1 inch margin on each side of the top of the box.

  • Have an adult cut three sides with a craft knife, leaving one edge connected.

  • Carefully pry open the flap. This will become your sun window. Fold the window up along the uncut line.

  • Glue the aluminum foil to the inside of your window, smoothing out as many wrinkles as possible.

  • Line the rest of the box with foil, inside and out.

  • Tape the black piece of construction paper on the inside bottom of the box, on top of the foil.

  • Glue the plastic wrap to the underside of the lid. Try to make the seal as airtight as possible.

  • Place a flour tortilla on a piece of aluminum foil and cover half of the tortilla with cheese.

  • Put the prepared tortilla (with foil underneath) into your oven and place outside in the sun.

  • Close the box.

  • Use a bamboo skewer, stick or dowel to prop the flap open.

  • Choose an angle that reflects the most light into the solar oven.

  • Cook! Check your food every 10 minutes. This could take anywhere from 20 minutes to 2 hours depending on how sunny it is outside.

  • When the cheese is melted, fold the tortilla in half and enjoy!
