The Chemistry students began "cleaning" their water sample today. They had a plastic cup, 2 pieces of filter paper, activated charcoal, sand, a needle, an eyedropper, a beaker, a graduated cylinder and a funnel. Using all of this, they can make their water sample pretty "clean". We'll finish cleaning tomorrow.
The AP Biology students worked on their own experiments involving cell respiration. Most student groups chose to look at other species besides germinating peas. One group used live crickets! We'll do some data analysis tomorrow and put the finishing touches on the Cell Respiration Lab.
