View Resource 4DEE Activity - Estimation of Animal Population Size

This activity is a lab exercise that teaches students how to estimate animal population size. It covers two main techniques: Mark and Recapture (MR) and Capture Per Unit Effort (C/UE). The MR methods include the Lincoln-Petersen and the Schumacher-Eschmeyer approaches. Three approaches for the C/UE method are also included. This exercise is aligned with the Ecological Society of America's Four...

View Resource Effects of Intraspecific Competition on Plants

This lab exercise examines the effect of density on the survival and growth of plant populations. Students examine a variety of parameters in experimental populations of radish plants grown at different densities. They evaluate their findings against the Law of Final Constant Yield and the Reciprocal Yield Law. This exercise follows the Four Dimensional Ecology Education (4DEE) framework...

View Resource How do Lake Ecosystems Change with Increases in Dissolved Organic Matter (DOM) and Reduced Water Clarity? Long-term investigations in lake ecology

Water quality is a significant issue affecting our lakes. While the effects of nutrients on water quality has received much attention, light availability also has strong effects on water quality in lake ecosystems. Light availability has been changing in many lakes with changes in water clarity. Many lakes are undergoing “browning”, where waters become darker and less transparent due to increases...

View Resource Redlining and Environmental Justice

In this lesson, we explore the inequity that exists in environmental health and nature because of changes we, humans, have made in our environment. Typically, people who have access to nature are generally healthier and have reduced incidences of respiratory illnesses (e.g., asthma), decreased blood pressure, and decreased chance of depression. Unfortunately, highly urbanized areas have higher...

View Resource Climate, Weather and Anthropogenic Activity

This module presents a science-based story to demonstrate how climate determines the global, long-term, large-scale distribution of living organisms; whereas, weather determines the local, short-term, small-scale ecology of living organisms. Life thrives within specific, often narrow ranges of temperature and precipitation – two main players in climate and weather. Using a systems-based approach,...
