Global Warming School Projects
Carbon Dioxide and Global Warming
- Some global warming theories state that increased carbon dioxide emissions are responsible for the greenhouse effect. Test these theories with the help of three fish tanks and some other items. Set up three fish tanks with about 2 cm of soil placed on the bottom of each tank. Seal one tank with the cover and masking tape to make it air tight. Create a small opening in the second tank and breathe air into that tank through the opening and then seal it off. For the third tank, create a small opening and insert a small rubber hose. Insert the other end of the hose through a small hole in the closed end of a plastic bag, sealing it with masking tape. Secure the bag over the exhaust pipe of a car. Run the car for 3 minutes, allowing the exhaust to fill the fish tank. Seal off the fish tank. Place lamps over the fish tanks to increase their temperature to 32 degrees Celsius. Record the temperature every 10 minutes for an hour. Compare the results for each tank.
Oceans and Carbon Dioxide
- The exchange of carbon dioxide between the ocean and the air is also affected by global warming. Students can see how this works by completing a project on this exchange. Fill two bottles or flasks about halfway with distilled water. Place several drops of indicator solution so that both bottles have the same color. Blow air into each bottle until the color changes in both bottles. Cover one tightly with its cover and leave the other one uncovered. Store the bottles in a location where they are not exposed to direct sunlight and cannot be spilled or knocked over. Monitor color changes in the water in each bottle over the course of several days. Note the changes and how quickly they occurred in each bottle.
Plants and Carbon Dioxide
- Plants are an efficient means of reducing the levels of carbon dioxide in the air. Fill three bottles half-full of distilled water. Place several drops of indicator solution into each bottle so that the colors match. Blow air into the bottles until the color changes. Cut several small sections of a plant, such as cabomba. Place the same number of plant sections into two of the bottles. Cap all three bottles and wrap one of the plant bottles in aluminum foil or black paper. Place all three bottles in a sunlit location. Once the color of the water changes in either of the exposed bottles, remove the foil from the third bottle and compare the colors of the bottles.
- Energy conservation is an important role that everyone can play toward reducing their carbon footprint and help reduce global warming. Students can audit their classroom or their own homes and share the results. Create a draft detector using a paper clip and a one inch by three inch strip of lightweight paper, such as tissue paper. Hold this paper strip by the paper clip near the cracks where doors and windows meet the wall and floor. If the paper moves, there is airflow and the door or window is not energy efficient. The location and settings on the thermostat can also be adjusted to create a more energy-efficient home or classroom. Keeping furnace and air conditioner filters clean and using energy-efficient light bulbs can also help reduce your negative impact on the environment. This project helps you determine areas to work on and identify where you have done well.
