This will address the Utah State core curriculum for 4th grade science, standard 3, objective 2 which is to “explain how the processes of weathering and erosion change and move materials that become soil.”
Content: I will show land features that address wind erosion, water erosion, glacial erosion, and how erosion has damaged ancient Egyptian artifacts.
Pedagogy: I would use the tour as a supplement to our class discussion and worksheets on weathering. I would set it up as a center activity to do with a completion assessment worksheet.
Technology:
Google Earth is a great fit for this topic. Instead of just looking at textbook pictures or at maps, the students can see how the landforms fit into their surroundings. I will also be including links to information web pages.
| Location | Activity Description | Google Earth Content |
| 1. Perito Moreno Glacier | Use the ruler to measure the width of the glacier. Follow the link and write down three interesting facts about the glacier. | Place marker, Ruler Layers: terrain, borders and labels |
| 2.Snake River | Follow the pathway along the Snake River. List three evidences of water erosion. | Place marker, Path tool Layers: terrain, borders and labels |
| 3. Sahara Sand Dunes | Look around at the variety of dunes. How does the wind affect the landscape. Look at the image overlay. What effect does the wind have when there is no vegetation to hold the soil in place? | Place marker, Image overlay Layers: terrain, borders and labels |
| 4.Sphinx | Follow the path through the pyramids to the Sphinx. Follow the link to read about uncovering the Sphinx. Use the slider to look at the Sphinx closely, then use the direction indicator to move around it. What evidences of erosion do you see? | Place marker, Path tool Layers: 3-D buildings, terrain, borders and labels |
