The lesson I am using for competencies based teaching is the second I taught in Environmental Science last year on Water.
This unit is based on two concepts that students have reviewed on different levels since kindergarten. These are geobiochemical cycles and energy transfers within a food web. The first step would be a pretest to see if students understand these basic concepts. After analyzing the pretests for each section the students will complete work needed to help in the understanding of concepts that aren’t at mastery level.
The students then focus on a specific county in Georgia and look at the pollutants in that watershed. The final project is to develop a presentation on how human activities are impacting that watershed, focusing on the relationships of the geobiological chemical cycles and the energy transfers in that ecosystem.
The outline of the lesson is here. Unit 02 Water Competency Based Instruction
