I was wondering if anyone could give me any ideas on an science fair experhyment that I could do on geothermal heating and cooling. Thanks. What I found out was – Some Ideas not exact Demonstrate small scale heating & cooling. Make students aware of closed loop systems, water or antifreeze solution is circulated through plastic pipes buried beneath the earth’s surface. During the winter, the fluid collects heat from the earth and carries it through the system and into the building. During the summer, the system reverses itself to cool the building by pulling heat from the building, carrying it through the system and placing it in the ground. Why use a Geothermal heating & cooling? To help prevent pollution of the environment from Fossil fuels like home heating oil, coal and wood. 5 gallon fish tank 1 inch ID Aquarium Pump polyvinyl tubing Sand stone Reptile Heating mat You will need to form a “V” on both side using the disposable aluminum cookie sheet cut to the outside of the tank. The “V” is to form the Earth outside. Step 1a. Lay down the Reptile Heating mat inside bottom of tank. Step 1b. Put polyvinyl tubing directly on mat close to side to be visible. Step 1c. Put 2″ of dark sand (8 cups) in 5-gallon fish tank. Step2. Place 1 five-pound bag of aquarium gravel on this layer of sand (mix the two together). Step3. Put 2″ of white sand (8 cups) on top of the preceding layer. Step4. Place 2″ of dark sand on top of the play sand layer. Step5. Put 1 five-pound bag aquarium gravel on this layer. Step6. You will now have a total of five layers of sand alternating from light to dark.
