Product Details

Daphnia magna, also known as water fleas, are transparent crustaceans that serve as an ideal organism to study the physiological responses to various stimuli. In this lab, Daphnia are exposed to both a stimulant and depressant as well as varying environmental temperatures. Students view the organisms under a compound microscope to observe the effect of these conditions on heart rate.

Includes detailed Teacher Notes with helpful lab hints, answers to worksheet questions, and a reproducible student worksheet. Complete for 30 students working in pairs. Daphnia magna and a compound microscope are required and available separately.

Performance Expectations

MS-LS1-3. Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
MS-LS1-5. Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.
MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
HS-LS2-1. Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.
