This module uses the Photosynthesis and Cellular Respiration Kit A ThINQ!TM Investigation Catalog #12005534EDU by Bio-Rad to allow students to observe the relationship between photosynthesis and cellular respiration by observing the change in color of a pH indicator as algae perform photosynthesis.

  • Suitable for General Biology and Environmental Science courses.

Learning Objectives

  • Students will use a pH indicator to detect relative CO2 and O2 in water.
  • Students will use algae as a model organism to observe how organisms influence their environment.
