Four Winds - October

Mrs. Corrigan and Ms. Rebecca visited us today to teach us about the agents of erosion. 
A favorite is always the puppet show! 

Our first experiment that showed us that one drop of water can cause erosion. We got to use baby bottles!

Our next experiment was to have a control group of rocks and water that we didn't shake and another that we each got to shake 10 times. Look at the water from both below. The rocks eroded! 

Then we got to go outside to use a bicycle pump to show how wind is an agent of erosion. 

Then we tried to build up our hillside so it wouldn't erode. We learned we would need a lot of boulders and trees. 

What great experiments!
