What Is Our Evidence That We Live on a Changing Earth?
What Is Our Evidence That We Live on a Changing Earth?
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
Below are digital resources that support teaching of this module.

Natural Hazards Viewer
A website with which you can search for several different types of natural disasters. To prepare the site for the Lesson 3 extension, select the Reset All Filters button on the lower left side of the viewer. Then select the check box next to Significant Earthquakes, Significant Volcanic Eruptions, or both. Use the search button for each of these hazards to limit the search to one year, possibly the year most of your students were born. Select specific events and access the information for students or prepare to show the viewer to the class and have them guide the selection.
