How to Make a Solar Oven


There are many great reasons to learn how to complete a solar oven! Maybe you’re going camping. Maybe you’re keen on learning about different ways to concentrate this sun’s energy. Maybe you’re interested in strategies of cooking that don’t add greenhouse gasses towards the atmosphere. Maybe you’re just hungry! In almost any case, as long as you’re patient and prepared to move your oven where the sun is usually, you’ll be rewarded with some hot, mouth watering food.

Several scientific phenomena initiate making your oven the best heater it might be. Heat is the form of energy (sometimes called thermal energy) that is certainly transferred by a difference in temperature. You intend to transfer the sun’s heat to your photovoltaic over. Reflection is the throwing back connected with light, heat or sound by a human body or surface, like a mirror. The shiny foil you’ll easy use in your oven will reflect the sun’s light and heat in your oven. During absorbing

Problem
Build and start using a simple solar oven.

Materials
Cardboard pizza pack
Pencil
Ruler
Box cutter or scissors
Lightweight aluminum foil
Clear type of tape
Black structure paper
Plastic wrap or large, transparent cheap bag
Newspapers
Oven mitt
Dish or pie plate
Cooking Ingredients, like those for some mores or nachos (don’t use your oven to ready raw meat)
Optional: a thermometer that comes up to 250 degrees F.



Procedure
Clean any stray items of cheese, sauce or crumbs out of one's pizza box.
Using the ruler and pen, draw a square one inch in from the edges of the top of the box.
Use the box cutter or knife to cut out three on the four sides of the square.
Make a crease along the uncut side of the square to manufacture a flap that stands up.
Cut a section of aluminum foil large enough to cover the inner side on the cardboard flap.
Wrap the foil tightly, in addition to secure with tape. What purpose does this foil serve?
Line the bottom of this pizza box with black construction paper. What exactly purpose does the black paper serve? Would white paper are well? Why or why not?
Cut two pieces of plastic wrap which might be the same size as the top of the pizza box.
Use tape to secure the plastic wrap towards inside edges of the square window you cut into your box. You are creating an airtight windows. Why do you want to make ones oven airtight?
Roll up some newspaper pages into tubes to stuff into your sides of the box. Make sure that you are still able to close the lid on the pizza box. Remember—what purpose does the classifieds serve?
Now it is time to make meals something! The best time to use one's oven is between 11 AM and 3 PM. Make sure to set the food using a dish so you don’t mess up the within of your oven.
One food option is usually a solar s’more. Place one or two marshmallows over a graham cracker. Put two to three squares of chocolate over the marshmallow. Wait until it’s done cooking to top it while using the second graham cracker. Any idea why it will be smart to have the chocolate on major?
You could also make nachos by placing grated cheese over tortilla chips, or use the oven to warm leftovers or soup.
Results
On a inviting, warm day, your oven could reach in relation to 200 degrees F. You will notice that food takes longer to cook within a solar oven than a regular one.

The reason?
Let’s recap: You covered the flap with foil so that the foil would reflect sunlight into the the oven. The black paper on the bottom of this oven absorbed the sun’s energy (white paper would have reflected many that energy). You made your oven airtight so that the warm air inside your oven would definitely not leave the pizza box via convection. You put the newspaper in your oven to insulate it and prevent warm loss through radiation. It is best to use your the oven between 11 AM - 2 PM because that is when the sun’s rays are strongest. If that you are making a s’more, it is good idea to give the chocolate on top because its dark color will absorb heat greater than the lighter graham crackers. Food takes longer to cook within a solar oven because solar ovens don’t receive as hot as conventional ovens. That’s okay for many people dishes, and using an educational oven such as one you made yourself adds an more special taste.

Going Further
Try making candy fondue or baked potatoes! Find out how solar ovens will be distributed in areas where there is little fuel but many sun.

, energy is taken in a material rather than reflected. You will line the inside of your oven with black paper so it can certainly absorb the light and heat being reflected with it. Another energy process you should be accustomed to for this project is convection, which would be the transfer of heat by the movement of any gas or liquid. You’ll use plastic wrap for making your oven airtight so the air warmed because of the sun doesn’t leave your oven through convection. One final energy term crucial to this project is insulation. Insulating materials keep heat leaving your oven through radiation. That’s why you'll line the inside of your oven that has a cheap and effective insulator—newspaper!
