High School, grades 9 through 12
High School Earth and Space Science
Algae do more than half of Earth's photosynthesis. Measure it in your classroom.
Algae sit at the center of the carbon and nutrient cycles, and at the center of the pollution problems that break them. These lessons let students grow a bloom, track nitrate, see plastic inside an animal, and connect it all to climate with their own data.
