January 16, Day 3

62/ Cartesian battleship. Tomorrow; cartesian bingo.

62/ Intro to molecules. Great lab from the American Chemistry Society. I made the following changes: After the water drop activity I showed the water balloon bursting video. More powerful this way. Then drew the various shapes on the board. Gave out more tasks verbally, did not use the lab write up as written by the ACS. Drop 5 drops on wax paper then observe shape and recall/redo the water drops on a nickel then draw the shape (curved versus straight edges) then cut the blob in half (requested the halves be equal in size) then cut those halves in half to give quarters and then remerge them and then tip the paper and observe the shape change as it races around then drag it around with the stick and then observe shapes and properties and then cut off the smallest drop possible and then the water drop race and then the unite the drops activity right away instead of as an extension. The kids were tripping out about water at this point. Focus disintegrated so I called it and went to clean up mode. When they get restless it means that it was a good lab. Tomorrow; atoms of water and hot and cold molecular movement and food dyes in water.

61/ Gym
