This is the website for the Environmental Science Activities for the 21st Century (ESA21) Project. You will find activities here that seek to engage individuals about environmental issues through investigating their impact on the environment. The activities are textbook independent, which means that the background material needed to understand them is either provided in or as a link from the activity. The activities rely on a mixture of hands-on, field, and Internet based experiences to give you a deeper understanding of the issues.
The links at the top and left of this page will allow you to access the activities in a variety of ways. The Activities link will take you to a listing of all of the activities that we have created. The Modules link has the activities grouped together around a particular topic, such as nuclear energy or wastewater, while the Pods link groups them around a much larger topic, such as energy or air. There are also links that go to ancillary products, such as instructor materials or assessments.
