Type of Resource



In this lab activity, students use brine shrimp as a proxy for krill to study how environmental factors impact behavioral responses of krill in the unique environment of Antarctica.

Performance Expectations

HS-LS2-6   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.

MS-LS2-4   Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
