This is a follow up on how to create a home for Earth worms, such as a terrarium and using the poop from the worm as compost for your garden or potted plants. It’s a cheap, simple and fun activity to do at school with your classroom, or your children.
- One clear plastic two liter bottle for each child with the paper taken off
- Eight to 10 red wiggler worms that can be purchased from any store that sales tackle and bait
- Two handfuls of newspaper cut into small strips
- One small bucket of water
- One bag of potting soil, the size depends on the amount of students that will be participating
- One bag of play sand
- Leftover fruit or vegetable scraps chopped into fine pieces. Do not add any meat or dairy products
- Black construction paper
1. Cut the top off of the plastic bottle
2. Soak one handful of newspaper strips and place it inside the bottom of the plastic bottle
3. Layer soil and sand between one cup of potting soil and one half cup of play sand until you have reached four inches to the top of the plastic bottle
4. Gently pour two cups of water inside of the bottle to moisten the sand and soil
5. Place eight to 10 red wigglers in your container by gently laying them on top, they will make their own way down the soil
6. Add one small handful of the fruit or vegetables on top
7. Soak the second handful of newspaper clippings and place it on top
8. Tape the black construction paper around the bottle because you are recreating what it looks like underground.
You have now created a worm terrarium and reaping the castings is next. The castings are small pellets that will be either stuck underneath the newspaper or as small mounds on top of the soil. It may take two to three weeks to get anywhere between a half cup to a cup full. And that’s about all you need to add to a potted plant. The castings are natural and an excellent source of nutrients in your garden.
