PHYSICS: So you’re on the lake fishing, when all of a sudden you think you see a snake jump into the boat with you. When you abandon ship and jump headfirst into the water, does the water level in the lake rise, fall, or stay the say? And why? Great topic for discussion! 
Here’s the lecture from Monday – the rest of Archimedes’ Principle. And if you want the solution to the problem at the end, a short, short video clip with just that is right below.

CHEMISTRY: We;ve almost made it! So why can bugs walk on water? Be sure to be able to describe the types of van der Waals forces, but also make sure you can apply concepts to answer questions just like this one. Like…..tomorrow on the paper chromatography lab!
PHYSICS: AWESOME, AWESOME, AWESOME! Awesome job on the King of the Hill competition! I don’t know that we’ve ever had a better one at SBEC. Thank you for stepping up and taking charge of your cars! I posted the pics and videos that Britteny took on Flickr – they’re in the badge over on the left of the page, and there’s also a sample one below. El Diablo was the fastest over the line, but the Mauve Avenger was more powerful and forced it’s way to victory! Taylor – I need the video you took, if I may (along with your play-by-play!). My SD card ran out of space before we got to the finals and I’d like to see/use what you filmed. Or do you call videoing with your phone, “philming”? I’m sorry, it’s late.
Congratulations, Nicole, on being King, or rather, Queen of the Hill! Also, congrats to Olivia and Trey for winning the distance and speed races. And congrats to the TNT Team of Tyler, Nicole, and Trey for garnering the most points to win the team competition. I’m very proud of all of you!
And speaking of winners, it’s occurred to me that I need to announce the winners of the Light Bulb Drop Project. I say winners, because – no, I’m not being indecisive, it’s because so many of you did so wonderfully well that I’ve decided to hand out several awards and appropriate prizes. Really!
Overall Winner and Most Creative Presentation – Nate W.
Most Creative Packaging – Taylor M.
Most Ingeniously Simple and Creative Design – Olivia W.
Smallest and Most Efficient Packaging – Austin W.
Largest and Most Layers of Creative Packaging – John Bailey C.
Best Use of Natural Resources – Micah D.
CHEMISTRY: So did it seem like we chased a lot of rabbits on Friday? Just wait til Monday! You did a great job applying the concepts you learned about dipoles and the rule “like dissolves like”. Why can you use peanut butter to get gum out of your hair? Why is it a bad thing to get water in your gas tank? And what about this one – so how do lava lamps work? Well, speaking of Monday, I really believe we need to spend the whole day talking about and exploring intermolecular forces. So……… I think I’m going to change things up a bit. We’ll move the lab on paper chromatography to Tuesday, review for the test on Wednesday, and then have the test on Thursday. I think this will also help all of you who are in the play. I know, I know, you’d rather take it Tuesday, but sometimes you’ve gotta do what you’ve gotta do! Love ya!!
CHEMISTRY: Hey guys, can you believe we’ve almost made it to the end of chapter 6? Here’s the lecture from Friday – intermolecular forces. (Don’t forget they’re called van der Waals forces!) Tons of application on these, everything from bugs walking on water to little fishes breathing dissolved oxygen (we’ll do that on Monday). Good luck as you begin studying for the test – I’ll be praying for you! You can do it!
CHEMISTRY: Do you need help with Lewis structures, molecular geometry, ionic bonding, etc.? Don’t forget about the help session tomorrow morning, 7:15 A.M. Don’t blow away tonight!!
CHEMISTRY: Just drawing arrows, right? Well that’s the last part of drawing dipoles. First, make sure you can draw Lewis structures, then draw the correct molecular geometry, then all you do is draw the arrow over the bond in the direction of the element with the largest electronegativity. Easy, huh? But man is it important. And it helps explain a lot. More tomorrow…
