Tuesday October 19 2010, Mrs Dressel's grade4 class went out to do a sand erosion experiment.
We went in groups of 3, 4 and 5. We made a mountain out of sand then we got a straw and blew through it to see what would happen if we did. Then we got a cup and poked a hole in it and put water in the cup to see what would happen if we put water on our moutain.
