Transcript of THE MOST AWESOME Solar Oven

Energy Involved
Solar Oven
Alex, Issy, Elizabeth

Light/Mirrors
In order to make our solar oven work, we needed light. Light is the form of energy that we used to make our solar over heat up and make the atoms inside the oven move faster. In some circles, that's also known as making the oven hotter.
Procedure
Materials: Aluminum foil, pizza box, plastic food wrap, kinects, black spray paint, mirrors, and duct tape

1. Spray paint the inside and outside of the pizza box black.
2. Use duct tape to tape aluminum foil onto the inside bottom of the pizza box. The foil should cover the whole inside bottom
3. Cut a 26 by 26 cm square in the middle of the top. Leave one side of the square on, forming a flap.
4. Inside, Put a small round aluminum foil bowl the height of the pizza box that is about 20 by 20 cm inside middle of the box.
5. Tape plastic wrap from the inside onto the square hole from the inside, covering the hole.
6. Wrap aluminum foil onto the side of the flap that is facing down.
7. Use double sided tape to tape three mirrors in the middle of the aluminum foil that is on the flap.
8. Put 27cm tall connected connects onto one of the corners of the flap so that the flap can stand up.
To make it work, put it in a sunny area and make the flap face the sun.
Good Luck!

There are three types of energy involved solar ovens. Those include Nuclear energy, Thermal Energy, and electromagnetic energy. Thermal energy is measured by calculating the total potential and kinetic energy of the particles of the atoms and molecules. Nuclear Energy is a type of potential energy that is stored in the nucleus of an atom. It is released during a nuclear reaction. Electromagnetic energy is a form of energy that travels through space as waves. Visible light is an example of electromagnetic energy. There are three ways to transfer heat. Conduction, convection and radiation. In convection, heat is transferred by the movement of currents within fluid. Radiation transfers energy by electromagnetic waves. Conduction transfers heat from one particle of matter to another with the movement of the matter.

The plastic wrap kept the heat inside
tin foil reflected
The black spray paint was able to harness the sun's energy because the color black attracts heat
focusing the light - there wasn't a specific hot spot because we didn't use a lens
Melting the marshmallow - There wasn't enough heat to melt it. If we had a lens, we might have been able to
Keeping the temperature consistent - Our temperature kept flucuating
Light
Mirrors
We also had to have some- thing to make the light go onto the cooking area of our oven. For this task, we used mirrors. The mirrors helped reflect the light onto the right place at the bottom of the solar oven.
The chapters in the Physical Science textbook on:
Mirrors and Light - We used lots of mirrors in our solar oven
Thermal Energy - We needed to know how to make a surface get hot fast!
Transfer Of Heat - We learned how to get heat from one place to another on our solar oven

It is very important to have a solar oven. You can cook food when your power is out, you can save a lot of money on the amounts of energy that you use, and it is also good for the environment. For example, ovens and stoves release chemical gasses that are harmful to the enviorment. It can help when there are energy shortages and to cook food in some areas of the world where they have no electricity.

For our solar oven to cook, we placed it in a sunny area with the inside of the flap facing the sun so the mirrors can reflect. If you are making Smores' you want to cook the chocolate first and then the marsh-mellow. Enjoy!
Solar ovens use thermal energy to cook a variety of food. Solar Ovens mainly rely on sunlight. Many solar ovens use reflection of the sunlight to focus the heat on a specific spot. Solar ovens usually are larger than a piece of paper in width and length. Many solar ovens also used lenses to focus the light and maximize the heat.
The chapters in the Physical Science textbook on:
Lenses - We didn't have any lenses on our design
Nuclear Energy - We weren't trying to blow anything up...
Basic Facts of Solar Ovens
Our group would have tried to focus the light differently by adding some lenses so that we could create a hotter solar oven. We would also try to make the foil reflect more light by making it face the sun.
