Grade Level: 4-5 elementary, middle school, high school, undergraduate.
Most carnivorous habitats have several different types of carnivorous plants, and most are located in and among the tangle of grasses and other bog plants. There can be many insects that serve as prey, but do some CPs have better odds over others at catching them?
In this inquiry investigation, students answer this question for Venus Flytraps versus Sundews versus Pitcher Plants versus Butterworts. They set up trapping hoods to control the variables of the investigation and make observations. Data is collected and analyzed. A graph is made, and studens draw conclusions from their data. This inquiry based approach provides a good understanding of the predator prey relationship and how it differs among Venus Flytraps, Sundews, Pitcher Plants, and Butterworts.
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.
