Lab: Predator-Prey Density: Venus Flytrap


Lab: Predator-Prey Density: Venus Flytrap

Purpose: Determine effect of prey density on capture rate in Flytraps.
Materials Provided:
    2 Potted Flytraps
    2 clear cover domes
    wingless fruit flies
    Student directions and data sheet
Grade Level: 4-5 elementary, middle school, high school, undergraduate.

Flytraps are amazing carnivorous plants. They have fast moving traps that are effective at capturing their prey, but only one meal at a time. Flytraps generally have several traps open at any one time.

In this inquiry investigation, students investigate the how crowding of prey affects the capture of prey. Students make observations, collect and graphically analyze data, make inferences, and draw conclusions. They end with a good understanding of venus flytrap prey capture in greater detail than simplying reading about it.

This series of carnivorous plant lab investigations is based on scientific inquiry standards of the National Science Education Standards, and are consistent with State Learning Objectives. Students have the opportunity to think and act like scientists during these investigations. Written and classroom tested by Michael Szesze, Awarding Winning Science Teacher.
