As you did in step 2, carefully use the utility knife to cut through one of the two cardboard layers where you want the flap to fold.
If the readings are different, make sure that the difference is consistent, and then use the difference to correct one of the readings so that the measurements can be compared. Turn the solar oven upside down and place it on top of the cardboard with the longest edges at the top and bottom.
You will need to remove it to move pots in and out of the oven. Set the inner box aside for now — you will not do anything more to it until step 9. In ideal conditions this solar oven can easily heat up to about to degrees F. Trace the outline of the base onto the lid, as shown in Figure 13, below.
To use the oven thermometer, keep the thermometer in the oven and then quickly open the oven and read the temperature if you are unable to read the temperature through the oven bag.
This makes a double layer of plastic.
Tip For best results, cook recipes on sunny days in the afternoon. Place the solar ovens side-by-side when testing them so that the conditions are the same for both ovens. Building the Solar Oven Base Fold the top flaps closed on the outer box and set the inner box on top. Keep the foil as smooth as possible.
And use caution when cooking with the solar oven as it can get quite hot.
Make pieces of foiled cardboard the same size as the oven sides and place these in the wall spaces. Make sure there are no holes in the plastic wrap and that all of its edges are completely attached to the lid. Sunlight hits the reflective surface and focuses on the hot dog held in the center.
Testing the Solar Oven's Performance You will now be testing the solar oven's performance. Check out the first link in the "More to explore" section for more efficient designs.
How does this compare with a real oven. It is lightweight, collapsible, inexpensive, and it works. This engineering project is best described by the engineering design process, as opposed to the scientific method. Were you able to cook a tasty s'more using your oven.
Stack the pieces on top of each other with one going inside of the other and tape or glue them back together to make an intact outer box that is the correct height. Do you have a good eye for beauty, balance, and form. Leave the solar oven outside on a hot day nonwindy days of at least 85degrees Fahrenheit work best.
Lest the dark bottom lining become dirty, it is better to use a clear plastic, glass or pie plate to hold the food.
For additional cooking techniques, look HERE. You will need to take every precaution with hot pots that you would take in the kitchen. Completed solar oven lid, with the prop holding the flap up. Record the initial temperature inside each oven.
Time how long it takes the solar oven to boil the water. What would the system look like. You should end up cutting the box into two pieces as shown in Figure 5, below.
Using full, direct sunlight is important for heating this solar oven—the sunlight needs to be reflected into the oven primarily from the aluminum foil-covered flap, but also from the inside of the boxand the heat must be trapped and retained inside by the plastic "window.
Preparation If needed, clean out the pizza box so it is ready to become a solar oven. Paint this black and elevate this off the bottom of the oven slightly with small cardboard strips. Or in a sporting goods store?.
Project #1: Solar Hot Dog Cooker This project is for older students or for younger students with adult supervision. The purpose is to use heat from the sun to cook the hot dog. The Science Behind Solar Cookers Part A: Introduction to Solar Energy and Solar Cookers Time: minutes, depending on the class need (See Appendix III for recommendations).
Jun 01, · A solar cooker is a device which is used to cook food directly under sun light without using Gas, LPG or electricity. It's a clean process of outdoor cooking.
Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our. Build A Solar Oven. LESSON THEME. An engineering Design Challenge to design complete a team challenge building a simple solar powered oven.
NATIONAL STANDARDS. National Science Education Standards (NSTA) Science as Inquiry Plan and manage activities to develop a solution or complete a project.
Aerospace Education Services Project. Have you ever wondered if it's true? Find out with this easy, fun, and delicious solar oven science project that uses only household items and a pizza box. Plus, learn about absorption, insulation, and the sun's energy.
