What Is Our Evidence That We Live on a Changing Earth? is part of Smithsonian Science for the Classroom, a brand-new curriculum series by the Smithsonian Science Education Center. It is aligned to a group of grade 4 standards. It has a focus on Earth and space science with a secondary focus on engineering. In this module, students:

• Analyze models of Earth, maps and globes, identifying patterns in the locations of major topographic features and occurrences of earthquakes and volcanoes

• Obtain information about the hazards associated with earthquakes and volcanoes and ways humans monitor such Earth processes

• Explain differences between wind-driven ocean waves and tsunami waves

• Design and test models of earthquake-resistant buildings

• Investigate weathering and erosion processes and explain the roles these processes have in changing the landscape

• Use fossils and structures found in rock layers to explain the appearance of former landscapes

• Propose a Smithsonian exhibit on Our Changing Earth that answers the module question
