This week we did a lot. This week we had a sub and a quiz on the same day. This test was on reading topographical maps. I hope I did good and if I screwed u hopefully you let us correct it. We also went outside and walked along our tributary. We saw were the two streams met. We also notice there were lots of rocks. You told us how the rocks cot here and how its a wash up zone. On Friday we did a experiment on how acid would affect chalk which is like a rock. When we broke the chalk there was a bigger reaction.
