High School Earth Science
Net Primary Productivity
How much new plant matter does a culture make?
Students measure how fast algae make new biomass and oxygen. They separate gross production from what the algae use themselves.
How the lab meets it
What students do that satisfies the standard
NGSS HS-LS2-4
Standard: Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.
What the kit does: Students calculate productivity from their own measurements.
NGSS HS-ESS2-6
Standard: Develop a quantitative model to describe the cycling of carbon among the hydrosphere, atmosphere, geosphere, and biosphere.
What the kit does: Students connect productivity to carbon taken up from the water and air.
APES
Where it fits: Unit 1, The Living World: Ecosystems.
What the kit does: Students measure primary productivity with a live culture.
