Solar Energy

Solar Energy This experiment deals with the testing of solar energy and what material holds the greatest amount of heat. Solar energy is heat that the sun gives off. The materials used to determine what holds the heat the longest are rock, soil, water, and stone. The purpose of this project is to see what of the four materials hold the heat the longest. My hypothesis is that soil holds the heat or energy the longest is because soil is black. Black is the number one heat tracker. The procedures I used in this experiment deal with how long a material can hold the heat the sun gives off and how long that material holds it. I got four thermometers and four cork plugs to see if water, soil, stone, and air could hold heat to see what material can keep the heat for solar energy. Ea Continue...

I would think that stone would be the coldest because it is a solid and solids can't hold heat as well as other materials can. The bottle filled with soil got to be the highest temperature of all the bottles. The reason water got to be a 106 degrees is because water can be heated by a surrounding temperature and can be heated by the sun's heat also. Each of the four bottles were tested for four days and all the temperatures differed only slightly. The four thermometers I used in this project were twelve inches long and were filled with red ink, rather than mercury. ch of the painted black bottles were placed in the sun. The choice of the four bottles would be soil. The bottle filled with water hit a temperature of 106 degrees. Soil proved to be the material that holds the greatest amount of heat. Air can't hold or store heat as well as the other three materials used in the experiment. This bottle had just about the same temperature as water. This temperature got to be 105 degrees, one degree lower than water. Some people also build their homes out of soil and rock as a good form of heating. My thoughts on the reason it got to be so hot is that, since the bottles were black and the soil is black the temperature of the bottle would be more hotter. This project could help indicate what materials work best in homes as a form of harnessing the heat also.
