PHYSICS: Good review today, are problems and concepts starting to come together? So here’s a look at some of the concepts and a problem from chapter 8. And don’t forget about the hollow ball! And lift!
Below that is the very short review we did from the Bernoulli worksheet – #5 & #6 and Alex’s look at the lift problem.

Bernoulli Worksheet
CHEMISTRY: Lot of numbers today! Here’s our discussion from today. How are you doing on writing nuclear symbols and hyphen notation – and we added ions? Can you can now use them to determine the number of protons, neutrons, electrons, etc.?
Now go forth and practice. 🙂

HON CHEMISTRY: Wow check out this awesome example of the photoelectric effect – a giant solar flower in Buenos Aires, Argentina! It moves as it follows the sun. Click on the link to learn more. There’s also a link below the vodcast. Giant Solar Flower
Great job role playing electrons today! Hey what about other applications of the photoelectric effect?
CHEMISTRY – Chocolate chip cookie dough model of the atom? That’s what Thompson thought the atom must look like! Here’s our discussion of how scientists began to determine the structure of the atom and the existence of subatomic particles.
For each, make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries. Wow, that’s a mouthful!
As we continue the explore the discovery of the structure of the atom, here are some video clips that I want everyone to watch that will help make things a bit clearer. Click here for the video on the Cathode Ray Tube Experiment that Thompson did, and also for the video clips that I want you to watch on The Discovery of the Electron and The Discovery of the Nucleus. All of these will be great tools in studying for the test!
Great brainstorming and discussion today on the Lost in the Chris RudgeBull Pass project. Here’s the recording from today. Good stuff!

CHEMISTRY: Here’s the our discussion on how we ended up with the atomic theory. Had you ever heard of Lavosier, Proust, and Dalton?
Pretty impressive little theory that Dalton came up with, huh? Were you surprised as you made comparisons with the Modern Atomic Theory? Could you now take it a step further and show connections between the three laws we discussed today and Dalton’s atomic theory?
PHYSICS: Were you amazed at the effect of change in surface area on the velocity of water, and especially the pressure of water, flowing through a tube? Thaaaaat explains how a calm ride on a lazy river can turn crazy in just a few seconds!
Today we concentrated on quantitative applications of Bernoulli’s Principle and a few practical applications. After ExploreZone we’ll begin taking a look at the problems and a couple more cool ways to apply Bernoulli!!
Welcome to a great adventure! You’ve learned so much this year – not just concepts, but skills, and you’re still learning! I can’t wait to see how you are going to apply it all!
Here’s the place where you can post your questions about the “Lost…”. First answer – the due date is Tuesday, April 15.
A really useful hint? Go back and re-read the project again – this time with a highlighter. It’s amazing how much I miss the first time I read something. So what’s your next question?
Do you need a copy of the project? Check under the Project tab.
DUE Saturday, March 22, 11:59 PM. This first worksheet is due for ALL 23 the items on the list. Submit Google Doc to your Chemistry Shared folder. Make your own copy before you start filling it in: FIRST Lost… Project Research Sheet
PHYSICS: Did you realize that fluids could produce that much force? Make’s you wonder at the awesome way God designed those beautiful under water sea creatures to withstand so much pressure, doesn’t it? This little creature is a lionfish from the waters of Lembeh, Indonesia.
Here’s the lecture on Pascal’s law and hydraulics and the like.
PHYSICS: So when you were floating in the pool this summer, did you enjoy your fellowship with buoyant forces? 🙂 From Wednesday – Archimedes’ Principle.
Great topic for investigation! Speaking of which – what did you find? When the kid jumped out of the boat, did the water level rise, fall, or stay the same? Hmmmm…..
