This video documents how scientists, using marine algae, can study climate change in the past to help understand potential effects of climate change in the future.

In this activity, students are introduced to tree rings by examining a cross section of a tree, also known as a 'tree cookie.' They discover how tree age can be determined by studying the rings and how ring thickness can be used to deduce times of optimal growing conditions. Next, they investigate simulated tree rings applying the scientific method to explore how climatic conditions varied over time.

The Electricity data browser allows individuals and organizations to create, download, or view graphs, reports and tables based on energy data sets for 2001-2013 from the US Energy Information Administration. Data sets include generation and consumption, sales, costs and quality. Can choose various ways to represent these data sets. Note: This site is being updated based on feedback from users.

This is a debate-style learning activity in which student teams learn about energy sources and are then assigned to represent the different energy sources. Working cooperatively, students develop arguments on the pros and cons of their source over the others.

This activity examines the impacts of hurricanes and storm surges on coastal communities.

This video looks at the impact of changing climate on animal habitats around the world, showing how different creatures are responding to changing temperatures and precipitation patterns.

This video provides background information and teaching tips about the history and relevance of phenology and seasonal observations of plants and animals within the context of rural Wisconsin.

In this visualization students can explore North American fossil fuel CO2 emissions at very fine space and time scales. The data is provided by the Vulcan emissions data project, a NASA/DOE funded effort under the North American Carbon Program (NACP).

In this short activity, students or groups are tasked to make concept sketches that track the source of electrical power as far back as they can conceive. The concept sketches reveal students' prior conceptions of the power grid and energy mix, and lead naturally into a lesson or discussion about energy resources and power production.

Students go through the design process and the scientific method to test the effect of blade design on power output. There is an optional extension to use the data to create an optimal set of wind turbine blades.
