This past Tuesday, 11/16/15, grade 3 had their first STEM class for the year. This is a brand new segment incorporating science, technology, engineering and math with a fun learning based project.
For this class we had an introduction to compost. I brought in buckets of materials and we spread them out over their desks. These materials included banana leaves, plastic wrappers, cardboard boxes, mesh sheets, drink cans, and plastic bottles. Each group of students had to sort the materials into one of three categories: Compost, Trash, Recycle.
We then discussed what makes materials compost. That is, how long it takes each material to break down and what materials release chemicals when they break down.
We then completed a small worksheet to help students understand what materials we use everyday that would be compost, mostly food vs technology.
After this we had a brainstorm session, writing down everything we use during the day from waking up to going home. We separated these materials into four categories: Trash, Recycle, Compost, Re-use.
