Here we tested tons of different objects from around the house to see if they would sink or float. Everyone got three turns testing. We always guessed before if we thought the object would sink or float. We learned that heavy things sunk and lightweight things floated. The Q-tip sunk because it absorbed water so quickly.

Then we learned that shape matters too. We tested two balls of playdoh that were identical in weight. (We made sure to measure on our scale) One ball we left as a ball and it sunk. Then I made the other into a boat and it floated. Then they all got turns seeing if they could make a boat to float.
Of course we needed to play in the water after our experiment because it was so fun. We even made some bubbles.

Today we learned about water pressure and did some fun experiments using water pressure. We learned that water pushes in all directions and tested that with cups and a hole punched in the bottom or side. We really tested water pressure with putting the cup IN the water. I realized afterwards the all the pictures I took are of them with their cups OUT of the water. Oh well...it was fun.
