"he Trans-Canadian Research & Environmental Education (TREE) program helps students explore the environmental history of their communities by analyzing trembling aspen tree cores and soil samples. TREE engages in science, technology, engineering and math (STEM) topics as well as social studies with Indigenous perspectives. The program was originally written to connect with Grade 8 curriculum but is easily adaptable and connects to concepts in grades 6-12."

This 2 day lesson includes a review on the twelve soil orders found on our planet and common soil testing procedures. Students will learn how to perform a soil ribbon test to determine the soil type, and measure the water holding capacity of a soil sample.

This final lesson in a sequence of lessons about tillage, agricultural practices and soil chemistry will combine all of the unit's content into a cohesive presentation that will prepare them for their summative course assessment. Course project soil data will serve as the foundation for the presentation.

Students investigate what types of materials biodegrade in the soil, and learn what happens to their trash after they throw it away. The concepts of landfills and compost piles will be explained, and the students will have an opportunity to create their own miniature landfill in which the difference between organic and inorganic waste will become clear.

Episode 3 of SARE’s “What is Sustainable Agriculture” video series provides an animated outline of the basic principles of conservation tillage. This is a basic explanation of conservation tillage and its benefits in agriculture.

The best way for students to understand how groundwater flows is to actually see it. In this activity, students will learn the vocabulary associated with groundwater and see a demonstration of groundwater flow. Students will learn about the measurements that environmental engineers need when creating a groundwater model of a chemical plume.
