Air pollutants act like the piece of glass trapping the sun's energy. This energy is stored in the air and in the water on the earth's surface. Solar Cells Solar cells convert the sun's energy into electricity. These cells are referred to as photovoltaics. Colormetric Absorption Students record the time and temperature in differently colored, water-filled bottles to determine which color best absorbs the sun's energy and stores this energy in the water of the bottle.
Solar energy is free, clean and forever.
This renewable resource is one of our best hopes for an environmentally sustainable future. The utilization of solar science to harness the energy of the sun is a growing and promising field of research and application for the future. Solar energy can be converted to heat or electric energy by a variety of methods. Below you will conduct several experiments to see how you can use energy from the sun. Back at school, students can discuss the results of these experiments and how they can use solar energy at school and at home.
