| Call it project insulation. | | | | to pick up. Let one jar uncovered so you can measure |
| Here is what you will need. | | | | the temperature in it. |
| - Gloves | | | | Carry the tray with the insulated containers on it |
| - Wool sock | | | | outside or in a garage where it is cold or cooler. |
| - Cotton sock | | | | Leave the jars for a set amount of time, let us say 15 |
| - Aluminum foil | | | | minutes. You can make it shorter if it is really cold or |
| - Leaves | | | | longer if you wish. |
| - Soil | | | | When the time is up bring the containers inside and |
| - Plastic foam | | | | remove the lids from each and take the temperature |
| - Other kinds of clothing | | | | of the water inside of each one. |
| - Fiberglass insulation (make sure to have your parents | | | | Record your findings on the graph paper. |
| help you with this and use gloves because fiberglass | | | | Also test the degree of the H2O cup that was not |
| can bother your skin) | | | | covered. It should be the coolest. |
| - Baby Food Jars with lids | | | | Compare all the jars. Which insulator worked the best |
| - Hot Water | | | | for this short time period? |
| - A thermometer | | | | Now do not dismantle your project just yet. Do the |

| Get hot water and pour into each glass. Quickly use | | | | What you will learn from this science project. |
