We are 1/20th of the way done with school. Is that good or bad? You decide.
AP Biology completed the first lab activity of the year, the Diffusion and Osmosis Lab. It took awhile but I think we learned a lot. Water potential was the main topic today. Water potential, if I could simplify it, is a measure of the tendency of water to diffuse from one area to another. Fresh water has high water potential compared to, say, a 0.4 M sucrose solution because of the presence of the dissolved sucrose in the solution. Fresh water would diffuse into this solution. Wow, sounds complicated doesn't it? Not really. I think all the students got it today.
Chemistry got a little messed up today because a fire....................just kidding. It was weird today though because the 10th graders were called out of class for what must have been a super important meeting because it was unannounced. And it was! The Josten's ring guy was here selling rings and stuff like that.
As a result, our first assessment of the year will now be on Tuesday, September 3rd. We did use the limited class time to put some finishing touches on the Measurement Lab which is due tomorrow at noon. Students are encouraged to submit it electronically if possible.
Oh yeah, I almost forgot. Congratulations to Kodi Kumpula for winning this week's prize for correctly calculating her age if the age of the earth was 24 hours. Kodi is only about 3/10,000 of a second old. She seems older though, doesn't she?
