Science 4 Inquiry
Let's Get Moving
Rivers top the list of causes of erosion over time. Scholars experiment with wind, water, and ice reshaping sand. They connect the simulations facts about erosion and deposition to understand unique landforms such as the Grand Canyon and...

The Grand Canyon
Fourth graders study the Grand Canyon. They research the Grand Canyon and locate the Colorado River on the map of Arizona. They discuss erosion and read how sedimentary rock was formed. They view photographs of the Grand Canyon and...

The Grand Canyon
In this geological processes instructional activity, students use Google Earth to access pictures of the Grand Canyon. Students look at the layering of rock over time. Students complete 2 short answer questions.

Slip Slidin' Away
Learners investigate mechanical weathering as a form of erosion. In this erosion lesson, students, define weathering and erosion before determining how the Earth's surface is in a constant state of change. They watch a video, access...

Weathering and Soil Formation
A set of 27 slides systematically shows how weathering, erosion, and deposition contribute to soil formation. Both chemical and mechanical weathering are described, as are resulting soil layers and properties. There is no longer any need...

Earth’s Ever-Changing Surface
The Grand Canyon formed between five and six million years ago, but is it still changing? Scholars explore 10 sites in the United States, including the Grand Canyon, to better understand the geoscience processes that formed these...
Curated OER
Go With the Flow
Students experiment with a simulated river bed and examine how erosion takes place faster with a young, fast-moving river than with a slow, older river.
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...
