September 10


First grade continued their study of matter with several gas (air) and liquid (water) experiments.

We placed a tissue in the top of a cup. Then we plunged the cup straight down into a tub of water. After we lifted the cup straight up, we discovered the tissue was still dry! What kept the tissue dry?

We placed a note card over the top of a glass of water and flipped the cup over. The water didn’t fall out and the paper stayed in place. Wow, air pressure is strong!
