This month Grade 2-4 have been learning about erosion, weathering and deposition. We did experiments to investigate the different types of each process. Here is Batiste’s account of what happened:

This month Grade 2-4 have done experiments. There were four but we were only able to do three. The first experiment was to take two chalks and two bowls. So then we took one chalk and put it in a bowl. Then we poured water in it. Then we put the other chalk in the other bowl then poured vinegar in it and we found out that the vinegar eroded more chalk than the water. It was very fun.

Another experiment we did was we took a box then we put 5 pieces of sugar in it. The sugar was supposed to be soft rock. So then we took the box and shook it. When we opened in the sugar was kind of broken. Then we put 5 pieces of gravel it then we shook it and the sugar was a lot more broken. So we found out hard stone can break soft stone easily. It was fun also.
