The Chemistry students began an activity on making their own Periodic Table - what fun! That Russian guy, Mendelev, was super intuitive when he created the Periodic Table for the first time. He even left blank spaces for elements that had yet to be discovered and when they were, they fit perfectly. He was cool!
The AP Biology students did a quick activity on enzymes and chemical reactions. We modeled an enzyme using our hands and toothpicks as the substrate. We calculated rate of reaction by timing how many toothpicks were broken using our hands. We even made a Andrew cross his fingers to model denatured enzymes. I think he got about 17 splinters.
