As a high school or undergraduate Biological Sciences teacher, you can use this set of computer-based tools in teaching about plant physiology, abiotic stress in plants, climate related stress factors and their influence on plant growth and development.
This lesson plan discusses abiotic stress in plants and their effect on plant physiology. Students will learn about plant stress responses like acclimation and adaptation to environmental changes due to climate change. Thus, the use of this lesson plan allows you to integrate the teaching of a climate science topic with a core topic in Biological Sciences.
The tools in this lesson plan will enable students to:

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.
Video lecture (~27 min)
Use this video lecture, “BIOPL3420 – Plant Physiology – Lecture 28: Plant Stress Responses”, by Associate Prof. Thomas Owens, Cornell University,to explain what plant stress is and to define abiotic stressors as the external factors that affect plant physiology. Then, list the factors that may affect plant growth and development by perturbing its physiology. Further, discuss the types of responses shown by plants due to changes in their environment like immediate responses, acclimation and adaptation. Use this tool to explain phenotypic plasticity in plants that enable them to extend their range or region of optimal growth. Finally, use the lecture to distinguish short term phenotypic plasticity from evolutionary adaptations exhibited by these plants in response to long term environmental changes.
Note: Following this introduction, teachers can choose to use either one or both of the following tools to discuss plant responses to abiotic stresses due to climate change related factors.
Laboratory activity (~105 min)
Use this laboratory activity, “Changing Planet: Withering Plants- Stressing Over Lost Water”, by Missy Holzer, Jennifer Bergman and Roberta Johnson of the NESTA/Windows to the Universe team, to enable students to explore the role of stomata in plants in regulating leaf temperature and controlling water loss from leaves under different environmental conditions. This includes a complete laboratory activity plan with background information in the form of a reading and links to other relevant readings and videos. A materials list and a link to download student worksheets is also provided.
Follow the directions, as mentioned in the laboratory activity plan. This will firstly, enable students to gain background information- through a reading and a short video- about the climate related factors like high temperatures and low water availability due to changing precipitation patterns, that can affect plants. Then, the students will prepare slides and microscopically observe the stomata in leaves and study their differences in plants grown in diverse conditions of temperature and water availability. Students can use the data from their observations to represent and compare the distribution of stomata using graphs, in different plants of the same species but grown under varying environmental conditions. Finally, discuss other plant physiological parameters that may be affected by climate related factors.
Video lecture (~18 min)
Use the video lecture, “Lecture 4c- Vegetation Response to Climate Change”, by Dr Lawrence Venable, University of Arizona, to summarise plant responses to climate change by discussing their impacts on native vegetation in Arizona. Reinforce student understanding about observed climate factors that could affect vegetation growth such as increased CO2 levels, higher global temperatures and changing precipitation patterns.
Then, emphasise how plants respond to such environmental perturbations in the short and long term by showing phenotypic plasticity, acclimation and adaptation. Encourage a discussion on how these climatic factors nudge vegetation growth in other regions than where previously found and therefore, cause a ‘range shift’. Finally, discuss how climate change can cause changes in phenology and affect percentages of different species in a population by influencing plant growth and development.
