Curated OER
Mini-Landslide
Students explore how different materials (sand, gravel, lava rock) with different water contents on different slopes result in landslides of different severity. They measure the severity by how far the landslide debris extends into model...

Watch Out for Landslides
Students conduct an experiment. In this landslides lesson, students learn about landslides and discuss how they could minimize the risk of landslides. Students complete an experiment to see if changing the slope of the land...

Two Rivers Ran Through It
Sixth graders discover the problems that early Mesototamian farmers faced while developing agriculture in the land between the Tigris and Euphrates Rivers. They design a working model that solves those unique challenges.

Weathering Agent 007
Students are introduced to the concept of weathering. In groups, they use the internet to research the various types of weathering agents and their effect on different materials. Using photographs, they discuss the role humans play in...

Erosion: Slip Sliding Away
Fourth graders investigate the causes of erosion. Through several demonstrations including one using sugar cubes and warm water, they observe the effects of erosion. In groups, 4th graders conduct similar experiments and record their...
