  1. My Solar Oven By Nathan Varnell

  2. Objective and Hypothesis My objective was to see if I could cook S’mores using a solar oven to harness the Sun’s energy. My hypothesis was “I can cook with a solar oven as long as the necessary conditions exist”.

  3. What I Used In this project the materials that I used were: a recycled pizza box, black construction paper, aluminum foil, heavy plastic laminate, non-toxic glue, tape, scissors, a ruler, a black marker, and two straws.

  4. What I Did To make my solar oven I first measured and drew out a one-inch border on the top of the pizza box. Next, I created a flap by cutting along three of the sides that I had drawn, leaving one of them uncut. I then folded the uncut side back, and glued aluminum foil onto it.

  5. What I Did [continued] After I put on the foil, I took the laminate and tightly sealed it onto the opening that I made, creating an oven window. Next, I lined the bottom of the pizza box with aluminum foil, then carefully placed and glued a sheet of black construction paper onto the foil.

  6. What I Did [continued] I carefully put two S’mores in the oven and placed it outside with the flap angled towards the sun.

  7. Finishing Touches. . . Finally, I took two straws and used black duct tape to secure them as props to keep the oven flap open, helping to direct sunlight into the oven. I left the oven outside for about an hour or two, occasionally checking on the progress.

  8. Conclusion • Objective: To cook S’mores with a solar oven. • I did not completely achieve this. It only made the marshmallows stick to the chocolate as they both softened slightly from the heat in the oven. • Reasons it did not completely work for me: • Cooler outdoor temperatures, lack of direct sunlight, plastic laminate might have been too thick, and I might not have had the oven at the proper angle to reflect the sun’s rays into the oven. Also, heat may have escaped from certain parts of the oven. • Hypothesis answer: • I believe that my hypothesis could still be correct as long as the conditions needed for success existed. • The things that I would change are: • A) Conducting this experiment when there is more direct sunlight. • B) Conducting this experiment in warmer outdoor conditions. • C) Finding a thinner plastic laminate. • D) Finding a better angle towards the sun. • E) Taping up the edges of the pizza box to keep heat from escaping.
