Solar cooking is the cleanest way to cook. Solar ovens are ovens that use the sun’s rays to cook food. Solar ovens focus the sun’s rays. The sun is a lot more powerful than people think. There are many different kinds of solar ovens to build or buy. Some of the ways to build solar ovens are with a funnel shape ( Jones ) or a box shape ( Bishop ). Solar ovens usually are covered in aluminum foil or a reflective material. Pointed toward what you are trying to cook. Solar ovens are used a lot in nonprofit organizations because of how cheap and easy to build they are. The solar oven is especially useful in a power outage.

Regular ovens are powered by electricity which like most things has its advantages and disadvantages. One advantage that has over the solar oven is you don’t need the sun to be out. A disadvantage is that if the power goes out you can’t use it. Solar ovens can’t cook when the sun isn’t out. Solar ovens also cost no money to operate. Regular ovens you have to pay an electric bill. Regular ovens cook faster than solar ovens. A lot of reviews online say that when you cook something on a solar oven it tastes better than on a regular oven. Solar ovens are a lot cheaper to buy or build. Some solar ovens are in the hundreds. If you build a solar oven it could cost under $20.00. Some regular ovens are in the thousands.

The earliest oven was made of brick and tile and was in 1490. Next came the iron stove 1720. Then came the Castrol stove in 1735. By the 1900’s most people had gas powered interior stoves. It wasn’t until the early 1930’s that electric ovens began to compete with gas ovens. (History ). The first known person to build a box to solar cook food was Horase de Saussure, a Swiss naturalist. The solar oven was made in the late 1700’s (A History of Solar Cooking).

Heat is transferred between substances. Heat and thermal energy are not the same. T hermal energy is usually not visible, but we can feel or see its effects. We use thermal energy for everyday things such as cooking, heating our houses, and to create electricity. “The faster the atoms or molecules move, the higher the temperature, and the more atoms or molecules that are in motion, the greater the quantity of heat they transfer.( Thermal Energy)

The sun’s core is 13600000 degrees C. The sun is larger than anything in our solar system. The sun is 92,960,000 miles from Earth. It makes up around 99.86% of the Solar System’s mass ( Fun Sun ). If the sun exploded right now you wouldn't know for 8 minutes.

A solar eclipse is when the moon covers the sun. The sun’s surface is 5,500 degrees C. The wind blows about 280 miles (450 kilometers) a second throughout the solar system. The sun is 4,500,000,000 years old. The sun is so wide it could hold 109 planet Earths inside of it. (// National Geographic // ) ?? = = = Works Cited =
