Our science investigation today helped students figure out what erosion is and what it does.  As mentioned previously, we planted some grass in 2L bottles.  We also made 2L bottles that looked like the river bank near our school and some with just dirt.  We made it “rain” and collected the run-off to compare what the different ground cover (or lack thereof) did to protect the soil.  When we came back in, we drew models to help us continue to Make Meaning of our investigation on Monday.
