Mark-Recapture Population Sampling

$9.95 – $67.95

How many spiders are hiding in the leaf litter?

How many plastic spiders are hiding in simulated “leaf litter”? Use the mark-recapture population sampling technique to estimate the number of organisms in a population.

  • Capture, mark and release a random sample of spider in your “leaf litter”.
  • Recapture a second random sample of spiders and use a mathematical equation to estimate the total number of animals in the population.

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

    Developing and Using Models - Develop and/or use a model (including mathematical and computational) to generate data to support explanations, predict phenomena, analyze systems, and/or solve problems

  • 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 - The significance of a phenomenon is dependent on the scale, proportion, and quantity at which it occurs.
