Cross Country Decomposers

Elementary, Middle

Description

This lesson help students understand, examine, and identify factors related to the process of decomposition. Students will learn that there are different rates of decomposition depending on environmental factors and the quantity of organic matter through a series of activities and by discussing with counterpart schools in another country.

The lesson is divided into two in-class lessons and 2 group assignments. The first lesson is a 45-minute brainstorm activity that will set the context and introduce the process of decomposition. Students will be observing and analyzing materials that will decompose and others that will not. This assignment will take up to 4-5 weeks.

The second lesson is another 45-minute in-class lesson, which will allow students to share and discuss their observations and findings. The final assignment is to create an article or photo story on a subject related to waste/litter. Students will be able to research their chosen topic and share their learning to create awareness.
