Observe and record information about the life cycle of the earthworm. Determine the effect earthworms have on the soil. Investigate the contribution worms make to composting. By participating in this activity students will gain a better understanding of the worm and its role in the recycling of organic materials into simpler forms. Worms can be used to help break down food scraps and other biodegradable products that might otherwise be discarded into landfills.
Worm compost is made in a container filled with moistened bedding and redworms.
Add food waste, and with assistance from microorganisms, the worms will convert bedding and food waste into compost. It is a natural method for recycling nutrients in food waste without odor. The resulting compost is a good soil conditioner for house plants, gardens and patio containers. Before beginning this activity students could research and investigate the life cycle and feeding habits of the worm. Worm research can be done via school or community libraries.
