Nature Walk -Decomposers

Secondary, Middle

Description

Decomposers are often seen as annoying insects, but we wouldn’t be able to live without them! During this lesson, students will go for a walk outdoors to identify common macro-decomposers in the schoolyard or nearby forest. They will explore and find various decomposers in leaf litter or a pile of compost using a rake and the reference chart. This activity will help students describe and understand the important role they play in decomposition process. After completing the outdoor component of the activity, students sketch and discuss the decomposers they found in the leaf pile.

General Assessment

Weaknesses

The reference chart does not have many examples and should have additional information added in order to help teachers and students see how many decomposers there are in our world. Students could prepare their own chart for their region before going outdoors.

Recommendation of how and where to use it

This easy-to-implement activity provides a terrific opportunity for students and teachers to address science and environmental studies outcomes through outdoor, hands-on experience.
