MARSHMALLOW MAN CHALLENGE!!!

Chemistry I students competed for a smarty pants point this week, building a marshmallow man that would expand when put in the vacuum chamber to demonstrate Boyle's Law.  The winner, representing 5th hour, was Jon Underwood with his "Incredible Hulk" marshmallow man.  Runners up included 5th hour's Bryce Markins and 1st hour's Sarah Powers.  Sarah's Marshmallow Man's eyes popped off and that was way cool!

CARTESIAN DIVER LAB!!!

Chemistry I classes created Cartesian Divers that would sink and float to the top of a water-filled pop bottle when you squeeze the bottle.  The concept demonstrate Boyles Gas Law where increasing the pressure on a gas lowers its volume.  It also shows how bouyancy and density can affect the diver.  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.

ALKALI METALS CHEMISTRY I LAB

ALKALI  METALS  LAB

Recently students dropped three alkali metals into water to watch as they produced flammable hydrogen gas and a base.  The base was indicated by turning bright pink in the presence of phenolphthalein.
