I used this quick and easy lab page with my 5th Graders to introduce organic and inorganic matter.
Each student received a plate with soil from our garden. They spent 15 minutes sorting through the soil with their hands, tooth picks, and magnifying lenses. Every time they found something in their soil they wrote it down on their paper.
Students loved playing with dirt!
At the end we wrote down our own definitions of organic and inorganic.
Hope you enjoy!
