This interactive shows the extent of the killing of lodgepole pine trees in western Canada. The spread of pine beetle throughout British Columbia has devastated the lodgepole pine forests there. This animation shows the spread of the beetle and the increasing numbers of trees affected from 1999-2008 and predicts the spread up until 2015.

This activity was developed to give participants an understanding of Earth's water cycle by completing a WebQuest and building a model of the water cycle.

Several activities that introduce students to the concepts of earth as a series of systems that are all connected. All of the activities reinforce the idea that water, air, soil, and living things all interact in the Earth system. There are several components that educators can choose to use: a book, a play, two activities, and two coloring pages.

This video documents the challenges that climate change presents for four specific Arctic predators: polar bears, Arctic foxes, beluga whales, and walruses.

This demonstration shows how water absorbs more heat than air. The corollary that is made is that the oceans are absorbing a lot of the heat related to climate change. The video tutorial shows an engaging demonstration that teachers can do live in their classrooms as part of a larger lesson/discussion about global warming. The video itself also includes an animation of how greenhouse gases contribute to global warming and concludes by mentioning simple solutions for students.

Students model the effect of greenhouse gases on Earth's atmosphere. They find that greenhouse gases, such as carbon dioxide and methane, are uniquely shaped to catch and pass on infrared radiation, and so they are responsible for the warmth we enjoy on Earth. The children discuss how the addition of greenhouse gases by human activities leads to further warming and what steps we can take to slow it.

This short video features the Alaska Lake Ice and Snow Observatory Network (ALISON project), a citizen science program in which 4th and 5th graders help scientists study the relationship between climate change and lake ice and snow conditions.

Students investigate how sea levels might rise when ice sheets and ice caps melt. By constructing a pair of models, students can observe the effects of ice melt in two different situations.

This classroom resource is a combination of 3 visualizations and accompanying text that illustrate how 3 key natural phenomena - cyclical changes in solar energy output, major volcanic eruptions over the last century, and El Nino/Nina cycles - are insufficient to explain recent global warming.

Students observe, sketch, and describe clouds on their own before learning to identify cloud types by comparing photos of different clouds to their sketches.
