Students will be introduced to the causes, locations, and hazards of landslides, as well as the role of satellite observations in predicting and studying them. To begin, students investigate the amount of precipitation sufficient to cause a... (View More) landslide in two different mediums (soil and sand), then use their findings in follow-up activities. After the lab, students will think about how rain information can be collected, especially via satellites, to model where landslides will occur. Finally, students will look at areas currently at risk of landslides and research landslide hazards and how to prepare for a landslide event, and create a public service announcement sharing that information. This lesson uses the 5E instructional model. All background information, student worksheets and images/photographs/data are included in these downloadable sections: Teacher’s Guide, Student Capture Sheet and Lab Instructions and PowerPoint Presentation.

Intended for use prior to viewing the Science on a Sphere film "Water Falls," this lesson introduces students to Earth's water cycle and the importance of freshwater resources.
Students will explore how energy from the sun is absorbed, reflected and radiated back into space by Earth. By completing three short labs investigating the effects of surface color, type of material, or cloud cover on temperature change, students... (View More) will begin to consider how various surfaces might affect Earth's overall temperature. Earth's energy budget will then be explored through a video, simulation activity, and an interactive animation. This lesson uses the 5E instructional model. All background information, student worksheets and images/photographs/data are included in these downloadable sections: Teacher’s Guide, Student Capture Sheet, PowerPoint Presentation and three lab sheets.

This activity is a short engineering design challenge to be completed by individual students or small teams. A real-world problem is presented, designing buildings for hurricane-prone areas, but in a simulated way that works in a classroom, after... (View More) school club, or informal education setting. Students are given simple materials and design requirements, and must plan and build a tower as tall as possible that will hold up a tennis ball while resisting the force of wind from a fan. After the towers are built, the group comes together to test them. If there is time after testing, which can be observational or framed as a contest between teams, students can redesign their towers to improve their performance, or simply discuss what worked well and what didn’t in their designs.
