Performance Expectations:

HS-LS2-1. Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.

  • Science & Engineering Practices

    Using Mathematics and Computational Thinking - Use mathematical representations of phenomena or design solutions to support and revise explanations.

  • Disciplinary Core Ideas

    LS2.A: Interdependent Relationships in Ecosystems - Ecosystems have carrying capacities, which are limits to the numbers of organisms and populations they can support. These limits result from such factors as the availability of living and nonliving resources and from such challenges such as predation, competition, and disease. Organisms would have the capacity to produce populations of great size were it not for the fact that environments and resources are finite. This fundamental tension affects the abundance (number of individuals) of species in any given ecosystem.

  • Crosscutting Concepts

    Scale, Proportion and Quantity - Students use algebraic thinking to examine scientific data and predict the effect of a change in one variable on another
