The purpose of this lesson is to have students understand the effects of certain chemicals or drugs on organisms by using Daphnia as a model organism. This level 5 inquiry activity was developed by a K-12 science teacher in the American Physiological Society퉌Ís 2010 Frontiers in Physiology Program.

This laboratory exercise is an experiment to test the size-selective predation hypothesis. Bluegill sunfish are placed in an aquarium containing a range of sizes of a crustacean, Daphnia, and fish stomach contents are examined to determine which size range was eaten. (less)

Using Esteem-style models to study two-species and three-species interactions in comparison with an in vitro situation

TWO ESTEEM-STYLE MODELS. ONE LOOKS AT TWO SPECIES THAT CAN BE MUTUALISTS, ... (more)

TWO ESTEEM-STYLE MODELS. ONE LOOKS AT TWO SPECIES THAT CAN BE MUTUALISTS, COMPETITORS, OR PREDATOR AND PREY. THE OTHER LOOKS AT THREE SPECIES THAT CAN INTERACT IN VARIOUS WAYS:CURRENTLY THERE ARE TWO CHOICES: A MODEL OF THREE COMPETITORS, OR A MODEL OF ONE PREDATOR CHOOSING BETWEEN TWO PREY. TO INCORPORATE THE COMPUTER MODELS INTO A WET-LAB, STUDENTS ARE DIVIDED INTO SIX GROUPS, EACH GROUP SETS UP SIX VIALS CONTAINING DIFFERENT COMBINATIONS OF CHLORELLA, OSCILLATORIUM AND DAPHNIA, THREE GROUPS ADD NITROGEN TO CULTURES. PREDICT WHICH VIAL WILL HAVE THE GREATEST POPULATION GROWTH FOR EACH SPECIES. OBSERVE POPULATIONS AFTER A WEEK. EXAMINE COMPETITION AND PREDATION USING ESTEEM-STYLE MODEL TO SEE IF DAPHNIA ACTS AS A KEYSTONE SPECIES IN THIS SITUATION. THE MODELS CAN BE ADAPTED TO OTHER ECOLOGICAL SITUATIONS AND PROTOCOLS.
