Curated OER
Date a Rock!
Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.
Curated OER
The End of an Era
Students explore the American-Mongolian paleontology expedition of Cretaceous fossil beds at Ukhaa Tolgod in the Gobi Desert. They present information about the life forms, tectonics, climate and geology of this time.
Curated OER
Tooth Detectives: Determining the Diets of Extinct Animals
Students study the teeth of living mammals and apply those skills to the interpretation of the diet of extinct animals.
Curated OER
Plate Tectonics: Recycling the Seafloor
Learners classify earth's layers and plates using Ocean Seismicity data. In this plate tectonics lesson, students outline where the plate boundaries are on the world map. They then compare these predicted boundaries with USGS map of the...

Searching the Digital Atlas
Learners become familiar with the tools of a digital atlas. They use a digital atlas of Idaho to located specified information. Students identify national forests, locate butterfly families, find examples of resident fish, and explore...
Curated OER
Natural Hazards
Students evaluate the hazards of naturally occurring events. After watching a video concerning safety hazards, students work in groups to discuss the safety issues involved in taking a trip to a mountainous region. Recommendations are...
Curated OER
Pass the Plate
Students define constructive forces. They describe how landforms are created as a result of constructive forces. Students recognize active volcano areas in the United States. They demonstrate an understanding of Panagea.
