Earth science projects are an amazing way for kids to become interested in science as well as the earth around them. “Earth sciences” covers a lot of territory – no pun intended – which gives kids a lot of choices for experimenting. Here are five great ideas for an earth science 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! Got more info here: “Does Salt Affect the Boiling Point of Water?
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. Instructions can be found at 24 Hour Science Projects.
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. Collect samples of different brands of tissue, weigh them, soak them in water so they break down. After 24 hours, rinse the samples through a funnel, then weigh the rest. Get the instructions for this earth science project called “A Straight Flush“.
