Earth science projects are an amazing way for kids to become interested in science as well as the earth around them. There are a lot of “earth sciences”, giving kids lots of cool possibilities for experiments and demonstrations. Here are five down to earth ideas for your project:
1. Find out if salt affects the boiling point of water. Using distilled water, measure the temperature at which water boils with different amounts of salt added. This easy experiment can be done fast – in under an hour!
2. Test types of insulation to see which works best. Freeze bottles of water, insulate them with various building materials, and see which one stays frozen the longest. This is science project is great for students concerned about our environment.
3. Make a tornado. Simply half fill a clear 2 liter soda bottle with water, and swirl it until it makes a tornado. This is an easy elementary demonstration, that probably won’t win the science fair, but will fascinate younger students while allowing them to observe swirling currents. (We bet you’ll get a kick out of it, too!)
4. Measure the amount of oxygen that is in air. Put duct tape on a hand warmer, activate it, and quickly tape it to the bottom of a tall jar. Invert the jar and put the mouth into a pan of water. As the hand warmer heats up, it will use up the oxygen in the glass, causing the water level to rise. If you’re traveling to and from the mountains and compare the amounts of oxygen, this is a great experiment. Otherwise, it’s a cool demonstration.
5. Compare brands of toilet tissue to see which is most biodegradable. Weigh samples of different brands of tissue, place them in water and allow them to break down. After a day, ‘flush’ the samples through a funnel, then weigh what is left. Your results may change your shopping habits! Get the instructions for this earth science project here.
