Curated OER
Law of Superposition
Students identify the law of superposition and it states that beds of rock in a series are laid down with the oldest at the bottom and younger layers on the top. They construct a legen for a block diagram and construct a block diagram...
Curated OER
Biomes: Extreme Climate
Pupils discuss the causes of global warming. For this earth science lesson, students examine how global warming is connected to the arctic and world climate. They write a paragraph about their interconnection.
Curated OER
Date a Rock!
Pupils figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.
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.

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
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.
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...
