Layer By Layer
Have your class learn about the formation of the Grand Canyon using this lesson. After listening to a variety of stories about the Grand Canyon and erosion, learners complete worksheets related to the geology of this area. What a...
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...
Curated OER
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...
Curated OER
"The Site Every American Should See"
Students research the natural wonders of the Grand Canyon. They write a descriptive paper about the Park. They also write a speech about why the Grand Canyon should be preserved.
Curated OER
The Grand Canyon
Learners act as scientists investigating the damming and experimental flooding of the Colorado River by the Glen Canyon dam that took place in 1996. They write a proposal as to whether or not more experimental flooding should be done on...
Curated OER
Erosion: Natural or Unnatural
Students explore how water has the power to erode, how developing the land (building roads, buildings and parking lots) increases the amount of water reaching our rivers, and how this greater quantity of water increases erosion. They...
Curated OER
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...
PBS
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
Erosion in Freshwater Ecosystems
Students explore the concept of sediment pollution. In this erosion lesson, students discuss the process of erosion and determine how sediment pollution affects animals that live in freshwater ecosystems. Students respond to questions...
Curated OER
Plop! Plop! Fizz! Fizz!
Fourth graders study physical and chemical weathering. They explain how the processes of weathering and erosion change and move materials that become soil. They create a K-W-L chart to show what they know and list what else they would...
Curated OER
Weathering and Erosion: Some Ways the Hydrosphere Affects the Geosphere
Students explain the causes of erosion, describe the effects of erosion, and devise a method of preventing erosion. They model the before-and-after-effects of erosion.
Curated OER
Bryce Canyon National Park: Hoodoos Cast Their Spell (64)
Students explore the natural wonders of this once remote area in Utah and explore how it became a popular tourist destination in the early 20th century. They examine how the region was used by Mormon settlers, scientists and the government.
Curated OER
Rocks
Learners examine how sedimentary rocks are formed. In this rock instructional activity students research different rock formations and different types of rock.
Curated OER
Let It Rain
Students study the effects of water erosion on soil by gathering and analyzing data during an experiment. They decide on appropriate units of measurement to apply in problem solving.
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
Using Cause and Effect to Write in Science
Fifth graders brainstorm processes or forces that cause Earth's surface to be changed.
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...
