Researchers designed two classroom experiments focused on the use of biochar as a soil amendment to improve soil health. The activities are aligned with the Next Generation Science Standards at the middle school level but can be adapted to high school classrooms (NGSS Lead States, 2013). Biochar serves as an ideal case study for students learning fundamentals of soil and plant interactions because it is easily accessible, connected to global environmental issues, and is the focus of ongoing research. Studying biochar also supports students in engaging in authentic science by discussing data variability and interpreting contrasting research results.

This detailed project report includes templates for teachers to develop their own classroom experiments with biochar.
