Solar cooker project
When the lid is done gluing, make sure it fits on the solar oven base as expected, as shown in Figure 16, below.
Figure 3. Vacuum tube type cookers can heat up even in the clouds and freezing cold.
This simplicity makes the design attractive, compared with using a paraboloid. For testing your ovens under the same solar conditions, you will need oven thermometers 2 identical ones or shallow black cooking pots with covers 2 identical ones.
It is possible to use two parabolic troughs, curved in perpendicular directions, to bring sunlight to a point focus as does a paraboloidal reflector.
Metal mugs are sold at camping stores and Wal-mart. Implementation of any Science Project Idea should be undertaken only in appropriate settings and with appropriate parental or other supervision. A dark colored metal or glass container works best and a handle makes it easy to hold and use.

Why or why not? While gluing the lid's corners, you can use binder clips to hold the corners together while the glue hardens. Main article: parabolic reflector Parabolic solar cookers concentrate sunlight to a single point. It may not be possible to safely or completely cook some thick foods, such as large roasts, loaves of bread, or pots of soup, particularly in small panel cookers; the cook may need to divide these into smaller portions before cooking. Reflectors direct the sun rays into the heat trap so that the box will heat quicker. It is lightweight, collapsible, inexpensive, and it works. Place some newspaper wads into the bottom of the outer box for the inner box to sit on top of. I developed the design and the recipes myself at the request of a kindergarten teacher for her classroom. Photo Credits:. On the other hand, there are disadvantages. Solar cookers use no fuel. Thank you in advance for your support!
Our top priority is student learning. If the axis of symmetry is aimed at the sun, any object that is located at the focus receives highly concentrated sunlight, and therefore becomes very hot. How many panels would your house need?

Cut The Corners of the Inner Box Step-3 Some twists of creased newspaper into the external box so that when you fix the smaller box down inside the hole in the external box, the pads on the inner box touches the top of the external box. Find out how solar ovens are being distributed in areas where there is little fuel but lots of sun. Commercial and industrial designers create the shape and form of every type of manufactured good that you can think of—from toys, sporting goods, and medical equipment to high technology products, furniture, toothbrushes, and toasters. Testing the Solar Oven's Performance You will now be testing the solar oven's performance. More mirror material is needed, increasing the cost, and the light is reflected by two surfaces instead of one, which inevitably increases the amount that is lost. Note: This engineering project is best described by the engineering design process, as opposed to the scientific method. It is a very easy project, but the younger children may need some help. The top can usually be removed to allow dark pots containing food to be placed inside. For most foods, such as rice, the typical person would be unable to tell how it was cooked from looking at the final product. Repeat step 2 at least two more times so that you have compared the two solar ovens in at least three trials. Attach the Small Box into the Outer Box Lastly, to make the drip pan, cut a part of cardboard similar to the bottom of the inner of the oven and apply foil to one side. They can be used to grill meats, stir-fry vegetables, make soup, bake bread, and boil water in minutes. We recommend about 2. For very young children, I would suggest that adults do the cooking.
So there are more menu possibilities.
