| Earth science projects are an amazing way for kids to | | | | probably won't win the science fair, but will fascinate |
| become interested in science as well as the earth | | | | younger students while allowing them to observe |
| around them. There are a lot of "earth sciences", giving | | | | swirling currents. (We bet you'll get a kick out of it, too!) |
| kids lots of cool possibilities for experiments and | | | | 4. Measure the amount of oxygen that is in air. Put |
| demonstrations. Here are five down to earth ideas for | | | | duct tape on a hand warmer, activate it, and quickly |

| 1. Find out if salt affects the boiling point of water. Using | | | | the mouth into a pan of water. As the hand warmer |
| distilled water, measure the temperature at which | | | | heats up, it will use up the oxygen in the glass, causing |
| water boils with different amounts of salt added. This | | | | the water level to rise. If you're traveling to and from |
| easy experiment can be done fast - in under an hour! | | | | the mountains and compare the amounts of oxygen, |
| 2. Test types of insulation to see which works best. | | | | this is a great experiment. Otherwise, it's a cool |
| Freeze bottles of water, insulate them with various | | | | demonstration. |
| building materials, and see which one stays frozen the | | | | 5. Compare brands of toilet tissue to see which is |
| longest. This is science project is great for students | | | | most biodegradable. Weigh samples of different |
| concerned about our environment. | | | | brands of tissue, place them in water and allow them |
| 3. Make a tornado. Simply half fill a clear 2 liter soda | | | | to break down. After a day, 'flush' the samples through |
| bottle with water, and swirl it until it makes a tornado. | | | | a funnel, then weigh what is left. Your results may |
