2nd grade review (March 23-27)

Erosion and Landscape changes

In science lab we have explored how our Earth is sculpted and changed by the power of water. Check out this great on line resources and find a river near you!

Directions:
  • Click on Go To Map, then type your location in the search box on the upper right.
  • Find a nearby river. To see where that river starts, choose Trace Upstream (at the top of the screen), then click on the river.
  • To see where the river ends, choose Trace Downstream (at the top of the screen), then click on the river.
  • For a surprise, search for the Mississippi River and trace it upstream and downstream. The Mississippi is the biggest river in the United States!

Things to notice: Where does water flow?


Next time it rains, look for puddles. Why are puddles in some places, but not in others? What do you think is different about the places where there are puddles?

Look at this hillside. Can you see anything that tells you where water has flowed? 

Draw a sketch of this landform and include arrows where you think the water has flowed. If possible, go outside and sketch other hillsides around you and include where water has flowed. If there hasn't been any recent rainfall, predict where the water would flow!
