Overview

As a high school or undergraduate Biological Sciences teacher, you can use this set of computer-based tools to help you in teaching photosynthesis, factors affecting photosynthesis, and the impact of increasing levels of atmospheric CO2 and some climate-related factors on photosynthesis. This lesson plan enables students to understand the process of photosynthesis in plants and the various factors that influence it. Students will explore how changes in climate related factors such as CO2 levels, temperature, water availability can influence photosynthesis, thereby impacting plant growth and agricultural yields. A hands-on lab activity will enable students to assess the change in the rate of photosynthesis when CO2 concentration changes.

Thus, the use of this lesson plan allows you to integrate the teaching of a climate science topic with a core topic in the Biological Sciences.
