A lesson plan for Grades 9–12 Advanced Placement Earth and Environmental Science and Earth/Environmental Science
In this lesson, students explore the work of scientist Tyrone Hayes and investigate the controversial issues surrounding the use of a chemical called atrazine.
Students will:
- explain how Hayes's cultural and life experiences influenced his career choice and locations of study;
- explain how studying animals' development may provide insight into environmental hazards; and
- examine the issues around the uses and potential hazards of the chemical atrazine.
Xpeditions provides links to all necessary web resources and questions teachers should use in order to engage students in discussion. This lesson also suggests assessment appropriate assessment and enrichment activities.
