This afternoon, we made an experiment to find out if air is matter. Matter is something that has weight and takes up space. We used a yardstick and put two balloons on the ends. Once the yardstick was balanced, we stuck a needle in one of the balloons and pulled it out so the balloon started deflating slowly. We proved that air takes up space and has weight because the yardstick started tipping to one side - the side that had the full balloon. So that balloon was heavier and it had weight! We love science in room 3. (We also are working in science groups and made funny names for them. That was a hoot.)
