How Do You Make An Observation Worm Farm?
You can make an observation worm farm to show children exactly how useful worms are for composting. You need to use a container that is narrow enough to force the worms to show you their underground environment. Any container that is too wide will allow the worms to hide from the light. Worms are easy to keep for a short time and need little care. This project should take between three to six weeks to allow children enough time to observe the different stages of composting. Modify your aquarium by placing the Plexiglas sheet in the aquarium, so your worm farm is about 3 inches wide. Duct tape the sheet in place if needed. Fill the farm with soil. The best type of soil to choose is from a healthy garden, preferably one rich with worms. Make sure soil is moist, but not saturated in water. Add worms. You can buy worms, dig them out of compost or harvest them from your garden. Red wigglers are the worms used in indoor compost bins. Garden earthworms are not used to living in small places.
