How Can We Stay Safe On A Changing Earth?

How Can We Stay Safe On A Changing Earth?

How Can We Stay Safe on a Changing Earth? is part of Smithsonian Science for the Classroom, a curriculum series by the Smithsonian Science Education Center. It is designed to address a bundle of grade 4 standards. In this module, students:

  • Investigate weathering and erosion processes and explain the roles these processes have in changing the landscape and revealing fossils.
  • Obtain information about the hazards associated with tsunamis and landslides and ways humans minimize hazards caused by such Earth processes.
  • Explain differences between typical ocean waves and tsunami waves, including their causes and the patterns they follow.
  • Design solutions to prevent landslides on a mountainside after a wildfire destroys plant life.
  • Develop a tool to evaluate sites for landslide risk to propose a location for a mountain-themed amusement park.

Below are digital resources that support teaching of this module.

Natural Hazards Viewer
This website allows you to search for several different types of natural disasters. To prepare the site for the Lesson 7 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.
