Composting Matters

Composting Matters is an engaging, hands-on unit that was designed for third-grade students. This unit was created with the intention of developing a deeper connection for students and the earth’s natural systems while introducing the theory and practice of composting and the important role that it plays in resource management and garden health. Students will be exposed to the process of decomposing and biodegradable materials through vermicomposting.
This curriculum is still under review by faculty. Units identified as Under Review have been submitted by educators. While they are available to view now, they are currently being reviewed by our curriculum committee for addition to this site.

Community Partner(s)

This unit would not be possible without the support from Kōkua Foundation (ʻĀINA In Schools) and Grow Some Good. Community partnerships play a vital role in the delivery of this unit, by adding value beyond the classroom in a meaningful and culturally appropriate way. Families will also be involved in actively supporting their children’s development and learning.


Essential Question
