View Resource Teaching Exponential and Logistic Growth in a Variety of Classroom and Laboratory Settings

Ecology and conservation biology contain numerous examples of populations growing without bounds or shrinking towards extinction. For these populations, the change in the number of individuals generally follows an exponential curve. On the other hand, limited resources may keep population numbers in check and help maintain the population at the environment's carrying capacity. These...

View Resource The Sustainable Use of Fisheries

The Evolution of Sustainable Use is a flash-based game that allows multiple players to simultaneously exploit a model fishery. The game presents a fishery as a metaphor for any communally-exploited resource. This imaginary fishery is scaled down so that the actions of 2-8 players influence the sustainability of the system. In the game “boats” represent the unit of fishing effort, and ea...

View Resource A Bird’s Eye View of Changing Landscapes: Using Google Earth to Explore Changing Landscapes

Students use Google Earth and satellite imagery from the United Nations Environmental Programme’s Atlas of our Changing Environment to discover ways in which landscapes change over time due to human actions and natural forces. By analyzing patterns in current and historical satellite images from locations around the world, students explore various types of landscape change and predict potentia...

View Resource Agapostemon sweat bee

As global food demand increases, farmers are increasingly relying on single, managed bee species (often honey bees) to pollinate their crops. However, honey bees are not the best pollinators for all crops, and honey bee colonies have recently been experiencing health problems, notably colony collapse disorder. Recent research has shown that promoting a diversity of wild insect pollinators – suc...

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...
