Algae in the ocean fixes more carbon dioxide than all the plants on the land.

Eutrophication and Nutrient Pollution

Add fertilizer and watch the water turn green.

Students add different amounts of nutrients to algae cultures and measure what happens. They see a bloom form and track nitrate as the algae use it up.

How the lab meets it

What students do that satisfies the standard

Grades 9-12

NGSS HS-LS2-6

Standard: Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.

What the kit does: Students test whether a nutrient change pushes a stable culture into a new state.

Grades 9-12

NGSS HS-ESS3-3

Standard: Create a computational simulation to illustrate the relationships among management of natural resources, the sustainability of human populations, and biodiversity.

What the kit does: Students use their bloom data to reason about how land use and runoff affect water quality.
