We love Spring time at our house. We are enjoying bursts of warm weather by getting outside a lot. We’ve been preparing our gardens for planting and have had fun finding lots of worms. I decided to let my kids explore worms some more with a worm tower. It is a great Spring science activity and a fun way to learn more about nature.
How to Make a Worm Tower:
To make a worm tower you need a 2-liter plastic soda bottle, dirt, worms, and some black (or dark colored) paper.
Cut the top off of the soda bottle and keep it. Fill the bottle with soil and gravel putting the gravel on the bottom and them soil on the top. Add worms into the bottle after filling it about half way.
After it is filled all the way, put the top of the bottle on, but flip it upside down so it is like a funnel. This keeps it closed, but allows you to add water into the bottle to keep the soil moist. Add a little water to the soil.
Cover the outside of the bottle with dark paper so that the worms have a dark place to tunnel through.
Let them dig around for a day or so, then you can remove the paper to see what they are doing in the bottle. There will be worms around the outside of the bottle that you can observe.
To find worms- dig around in your yard. It’s lots of fun to find them and let the kids feel them and watch how they wiggle. We added a whole bunch- I think around 15 worms to ours.
