| this accurately. | | | | For fun lets use eggs to test this. They are so useful |
| Lets get some ingredients: | | | | for so many things. Put the egg into the glass with just |
| - Glasses | | | | water. The egg should sink to the bottom of the glass. |
| - Water | | | | Record this on your graph paper. You may want to list |
| - Salt | | | | all the ingredients on the bottom of the graph paper. |
| - Sugar | | | | Now remove the egg with a spoon and dry off with a |
| - Powdered laundry detergent | | | | paper towel. Lower the egg into the next glass and |
| - Baking Soda | | | | see what happens. Record if the egg went to the |
| - Flour | | | | bottom, floated or was somewhere in the middle. |
| - Pepper | | | | After each cup is experimented, remove the egg and |
