Good Morning people of 3rd period! Due on Friday was Pg. 1001 #17-19, 21, 29-35, 40-42. We then went over the homework and Coats-Haan worked out questions on the board. And Coats-Haan introduced the temperature take-home lab. Coats-Haan then talked about if "you are taking an AP Test in the morning and your "brain is fried" afterward then I totally understand if you stay home." Or "if you are taking an AP test in the afternoon and you want to get extra sleep and make a nice breakfast I totally understand as well". Also if you are missing for AP tests you need to talk to Coats-Haan individually. Then after that brief conversation, we talked about Mr. Gleason for a little bit, and then we took out page 223 from our lab manual and watched part of the amazing movie Nova: Chernobyl Video. We will finish up the movie on Monday! There are no assignments or homework for the weekend except to study for the Nuclear Quiz on Monday :(
QOD:
Q: What were some of the key mistakes made at Chernobyl?
A: The key mistake was the kind of reactor system they were using. They were using a less pure Uranium. So when the reactor ran out of water the chain reaction increased in speed and then began to get hotter and hotter until reactor #4 caught on fire.
Another design flaw was the structure of the control rods.

5/1 Vidas
Today was a lovely day in Honors Physics. We began class by turning in the homework questions, which were on pgs. 217-220 in the lab manual. The carbon dating problems were not collected, and we checked them using a key that was on the board. We had a twilight zone moment when Coats-Haan realized that somehow the key had already been changed to say 2012, and she did not do it this morning... *cue creepy alien music*. Next, we talked a little bit about radiation and superfund sites. Which leads us to our fabulous question of the day!
QOD: What is a superfund site and where was the nearest one located?
A: A superfund site is an uncontrolled or abandoned place where hazardous waste is located, possibly affecting local ecosystems or people. This "hazardous waste" usually contains toxic substances, or more often, substances that emit radiation. The nearest one located was Skinner Landfill in West Chester. Luckily, the site was cleaned up, so thankfully no one in our class received any dangerous radiation!!
After we talked about superfund sites, we watched a short video on Yucca Mtn. And when I say short, I mean about 30 seconds... blink and you miss it! Then Coats-Haan set us loose to work on the "Particle Adventures" webquest, on the lab manual pgs. 213-216. Since we did not finish this in class, it will be due at the beginning of the period tomorrow.
