How Can We Stay Safe On A Changing Earth?
This module is currently being field tested and is not yet available for purchase.
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 adventure park.
