High School Life Science
Carrying Capacity and Population Dynamics
Count a population until it hits its limit.
Students grow brine shrimp on algae and count them over time. They change the food or the oxygen and see where the population levels off.
How the lab meets it
What students do that satisfies the standard
NGSS HS-LS2-1
Standard: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
What the kit does: Students graph population counts and use the curve to explain what limits carrying capacity.
NGSS HS-LS2-2
Standard: Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales.
What the kit does: Students change food or oxygen, collect new counts, and revise their explanation from the data.
