Worms:
For young kids: Math: counting, size comparison, volume measurement, time: How long does it take the worms to eat a slice of banana vs. a slice of apple.
Science: Comparing worm growth based on types of feed given, temperature. Research regarding how worms reproduce.
For older kids: comparison between standard composting and vermicomposting, More research regarding reproduction, comparison of temperature in vermicompost vs. standard compost. comparison of plant growth with and without worm castings added to soil. Kids could come up with their own questions and hypothesis regarding the goings on in the bin, and plan their own experiments.
For kids of all ages: sensory integration, and an appreciation for life cycles.
