The AP Biology students began the first lab of the year, the Osmosis and Diffusion Lab. The students learned that, yes, molecules do indeed move from an area of high concentration to low concentration. If the opposite was true, no one would smell anything besides what is already inside their nose. I'm pretty sure that's true.
The Chemistry students finished the Scientific Inquiry Lab today and in doing so they learned that a lot of people misuse the word 'theory'. If someone says "well, that's only a theory", they A. don't know what the word means and B. they are probably obnoxiously stupid. I also showed the students how to make a simple cannon out of their Mom's turkey baster, alcohol and a ping pong ball. Awesome chemistry knowledge was totally dropped today.
