Activity Overview

Students will use a Colorimeter to compare the rates of photosynthesis for plants in different light conditions. They investigate the role of chloroplasts and light on photosynthesis.

Key Steps

Comparing boiled and unboiled chloroplasts in the light with chloroplasts in the dark over 20 minutes, students study the process of photosynthesis.
Linear regression is used to find the rate of photosynthesis.
