Product Description

By: The Flinn Staff

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.
