A lesson for Students Grades 9 - 12 in Biochar:
This is an interdisciplinary activity for grades 9 – 12, revolving around use of biochar to mitigate climate change and promote sustainable agriculture / horticulture. It involves climate science, plant science, and chemistry. Advanced students will also encounter some elementary combustion science and thermodynamics, soil science, and botany. The activity includes hands-on construction and use of a device to make biochar, as well as planning and conducting a controlled experiment to test the effects of biochar on plants in their native soil.
