Visualize how our atmosphere has changed with this hands-on model!

Earth's atmosphere has dramatically altered since the planet formed 4.6 billion years ago. From its formation as a molten planet to the emergence of life the atmosphere has evolved. Your students will actually visualize these changes as they construct their 3-D model.

First, your students make their models of the atmosphere at different times. Then, they use it to make comparisons at how it has changed and what has caused this to happen. The model covers the time from Earth's primordial atmosphere through different stages as volcanoes, comets, meteors, water and life played their part.

The Atmosphere Evolution Model Making Kit includes enough materials for students to assemble up to 5 paper models working cooperatively. The comprehensive Teacher Resource Guide included provides illustrated readings, activities, key vocabulary and an assessment, along with teaching opportunities for students to Engage, Explore, Explain, Extend and Evaluate their understanding of the concepts presented.
