Mrs. Lau's 7th Graders visit PCHS Lab!!!


Winning CARTESIAN DIVERS:  Karson (overall winner), Devyn, and Caitlyn
Chemistry Club students recently helped Mrs. Lau's 7th graders create Cartesian Divers that would sink and float to the top of a water-filled pop bottle when you squeeze the bottle. The concept demonstrate Boyle's Gas Law where increasing the pressure on a gas lowers its volume. It also shows how density affects the diver's bouyancy. Amazingly, you can use a Heinz ketchup packet as a diver as well! Here are the winners of the diver races and some pics of students making them in lab.
