Pond Ecosystems and Climate Change


As an Undergraduate Biological Sciences teacher, you can use this set of computer based tools to enable students to develop a comprehensive understanding about the structure and function of an ecosystem, with a focus on hydrological ecosystem, and biotic and abiotic components of the ecosystem. You can do this through a study of ponds and pond ecosystems and its comparison with freshwater and saline water ecosystems.

In this lesson plan, students will learn that increasing temperatures may alter the patterns of several ecological roles performed by ponds such as – water storage, habitats for plants and animals, water quality (filtration), groundwater recharge, and shifts in cycling of nutrients (biogeochemical cycles). They will learn about the correlation between climate change and reduction of biodiversity in pond ecosystems, through an activity that focuses on dissolution of carbon dioxide and its impacts.

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 . 

Learning Outcome

The tools in this lesson plan will enable students to:

  1. Learn the core concepts of ecosystem, biotic and abiotic interactions in ecological pyramids, more specifically in the context of hydrological ecosystems.
  2. Understand the importance of pond ecosystems in maintaining ecological balance
  3. Critically analyze pond ecology, and the impact of human activities in altering the aquatic ecosystem. They will also learn effective measures for the recreation of a pond ecosystem.
  4. Further discuss the role of pond ecosystems in food security
