This week, we built puff mobiles with a group. A puff mobile is a car made out of 10 straws, 4 beads and one sheet of paper. To make it move, you have to blow on it. After we finished making our puff mobiles, we had a big puff mobile race. The race was in the gym and the whole fourth grade was there. In our class, The Hurricane Mobile and Flamerunner had the first ever "puff off". Flamerunner was the winner of the puff off! The winner of our class race got to go to the finals, but he didn't win. The finals were one puffer from each fourth grade class. Only one car won each race. Then we had a race of girl puffers and a final. Then we had a race of boy puffers and a final.

In writing, we finished our rough draft of our Bio Poems. In science our grass started to grow and we measured it every day. Last week we made our terrariums. We noticed the water cycle happening in them. It was really cool. (Thanks to TP and AJ for writing our class blog this week!)
