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.
Use this lesson plan to help your students find answers to:
- What is photosynthesis?
- What are the key differences between C3, C4, and CAM plants?
- How do plants respond to climate change?
- Discuss the impact of increasing global CO2 levels on photosynthesis.
- Is global food security at risk due to climate change? Explain.
This is a Teacher-submitted Lesson Plan.

About Lesson Plan
|Grade Level||High School, Undergraduate|
|Topic(s) in Discipline||
|Access||Online, offline use|
|Micro-lecture (video) (~12 min)||A micro-lecture (video) that introduces the topic of photosynthesis|
|Micro-lecture (video) (~7.5 min)||A micro-lecture to learn about how plants have evolved to respond differently to changing climatic conditions.|
|Reading (~20 min)||A reading to discuss the difference in the responses of C3 and C4 plants to rising levels of atmospheric CO2|
|Classroom/ Laboratory activity
|A classroom/laboratory activity to measure the rate at which photosynthesis occurs and note changes under variable conditions such as elevated carbon dioxide levels, a potential contributor to climate change|
Here is a step-by-step guide to using this lesson plan in the classroom/laboratory. We have suggested these steps as a possible plan of action. You may customize the lesson plan according to your preferences and requirements.
|1||Introduce the topic by playing a micro-lecture (video)||
|2||Discuss the topic further by playing a video micro-lecture||
