This is a fun-science activity for children to understand what worms do and how they help to mantain the soil rich and help the flowers and plant grow.
You need:
- a glass jar
- some sieved soil
- dead leaves
- earth warms
- a dark cloth
1) hunt for some worms with the children (they must be big mature warms!), 4 or 5 should be enough
2) put them in a container with the soil you found them in
3) get your jar
4) fill the jar with one layer of about 3cm of soil, then spray some water and fill the jar with another 3 cm of soil, spray some more water, leave only about 5 cm from the top
5) put your warm in the jar
6) cover them with the leaves
7) cover the jar with the dark cloth and put it in a dark place
After a couple of days go and observe the jar. there should be worm tunnels, you should see some leaves dragged into the soil.
When you have finished the observation relise the worms in the garden...the soil they where housed into will be very nutritious for your flowers!
