What happens when worms are under the ground? Make a mini worm farm and see exactly what happens. Make your predictions and watch as it unfolds before your eyes .Science experiments are all about observing so watch and learn with science.
What you need
- large plastic bottle
- earthworms from the garden

- cling wrap
- dark/black paper
- a pencil
- Cut the top off of a large plastic softdrink bottle.
- Fill the bottle with layers of soil and sand.
- Add 4 teaspoons of water to the soil and put dead leaves at the top of the soil.
- Dig around in the garden outside and try to find 2 or 3 earthworms and add them to your soil.
- Cover the bottle with cling wrap and poke some holes in the top with a pencil.
- Sticky tape the dark paper around the sides of the bottle.
