This lesson is designed to help students use appropriate tools and techniques to gather, analyze, and interpret data; develop descriptions, explanations, predictions and models using evidence; develop an understanding of the Earth as a system by understanding that global patterns of atmospheric movement influence climate, including local weather; and understand that internal and external processes of the Earth system cause natural hazards (volcanoes) that can change or destroy human and wildlife habitats, damage property and harm or kill humans. Students will demonstrate numerous cooperative learning strategies in response to a presentation of basic concepts. They will also collect, analyze, and interpret data, and make predictions based on its synthesis. The lesson provides detailed instructions as well as worksheets, charts, internet access, and publications.
