Computer Interfacing

Experiments


Several experiments that make use of computer assisted data collection are described below. Although these are copyrighted materials, feel free to copy, modify, and use them in your classroom with your students.

Experiment 1

  • Catalase Enzyme Activity: This experiment measures the rate of enzyme activity in organisms containing either catalase or peroxidase. The pressure sensor is used to monitor oxygen production as hydrogen peroxide is destroyed. This experiment fits well with studies of enzymes and cellular metabolism.
  • Teacher's Information for Catalase Enzyme Activity: Find tips, directions for making solutions, sample answers to questions, sample data and plots here.

Experiment 2

Experiment 3

  • Transpiration: This experiment determines the stress various environmental variables have on the transpiration of water through the leaves of plants..
  • Teacher's Information for Transpiration: Find tips, directions for making solutions, sample answers to questions, sample data and plots here.

These experiments are from Biology With Computers, © David Masterman, 1996, distributed by Vernier Software.
