| Did you know that earthworms are some of the most | | | | layer of soil |
| important and useful animals? They are very important | | | | 6. Take the dark construction paper and wrap it |
| to human life and here is an experiment to see how | | | | around the jar to make sure you keep out all light. |
| they survive and why it is useful to us. Please handle | | | | 7. Secure the construction paper with the sticky tape |
| the earthworms with care and make sure you do not | | | | to keep it in place |
| harm them at all! | | | | 8. Now you have to check the soil every now and |
| Here are the supplies you will need for your | | | | again to see what happens |
| earthworm science project: | | | | 9. Remember to replace the dark construction paper |
| - A large and wide-mouthed, clear glass jar | | | | every time and of course you have to take a photo |
| - Gravel and small pebbles | | | | every time for your display |
| - Soil | | | | 10. The idea is to observe the behavior of the |
| - A tin can | | | | earthworms for a while and once you are done, you |
| - About 6 earthworms from your garden or anywhere | | | | have to place them back safely in the garden, they |
| you can find them | | | | are very precious |
| - Dark construction paper | | | | 11. Make very sure you do not harm them in any way |
| - Sticky tape | | | | Now, why did you do this experiment or project and |
| - A camera | | | | what did you see? |
| Now this is what you have to do: | | | | The earthworms feed on the soil by taking it through |
| | | | their bodies. In this way the worms form tunnels that |
| 1. First of all, the camera is to take photos of your | | | | aerate the soil. This aerated soil provides the plants |
| experiment, every step of the way as you go. | | | | with the oxygen they need to grow. |
| 2. Place the tin in the middle of the jar | | | | This is why they are such an important part of the |
| 3. On the bottom of the jar place a layer of gravel and | | | | animal world. Without the earthworms many plant |
| pebbles of about half an inch | | | | species will not be able to survive and we will not have |
| 4. The layer of gravel and pebbles needs to be | | | | enough food. |
| between the can and the glass of the jar | | | | The conclusion of our easy earthworm science |
| 5. Now you fill the jar with garden soil up to the height | | | | project is that earthworms aerate the soil and is vital |
| of the tin can and place the earthworms on top of this | | | | to plant life. |
