How To Make A Solar Powered Oven Science Project ?

While choosing for a wining school science project, innovation, benefits and sustainability of such a project are among the most crucial factors to be taken into account. Many projects may partially or fully meet such criterion but solar oven stands out over the rest. Its simplicity, low cost and the enormous benefits accruing are marveling. Adequate time for preparation and collecting of necessary material should be allowed, a fortnight on the least is enough. An adult is needed for guidance especially on the intricate stages and the safety of the participants.

There is a variety of solar oven for the participant to choose from. Parabolic solar oven, box cooker and collapsible panel oven are among the ones they can chose from. Collapsible oven is particularly ideal for the project since it has extra benefit of being foldable for easy storage and portability. Having identified the type of the oven make a check list of the items needed.

  1. A cardboard box preferably. This can be obtained for free or at a small fee. Normal boxes like the one used to pack computers or wrap glass materials can do. A thin coat of paint can be applied on the card board to make it water proof. Remember the cooker is outside much of the time.
  2. Aluminum foil.
  3. Glue and adhesive tape.

The procedure commences with cutting the card board material into two pieces. Cut it in such away that each square side retains its flab resulting into a rectangular shaped peace. Next draw the lines on the square portion of the rectangular piece. The lines should be in such a way that if you fold along the lines you will obtain a conic-shaped structure with several panes. After doing the same to the remaining piece, cut half way the flab along the edge where it is attached to the square portion.

Fold each piece along the lines drawn to obtain two corresponding half conics and put the aluminum foil lining on the inner side of each card board. Glue them together to obtain a collapsible solar oven.

Put food in a suitable cooking vessel and place it in the cooker. The cooker should be placed at an angle aligned to that of the incoming rays of the sun. These rays may often assume different angles depending on the position of the sun. Place your cooker in a location that is free of wind because of stability. The cooker can generate heat of up to 100 degrees centigrade and suitable for boiling and baking.
