SBEC Chemistry and Physics » Welcome http://tskinnersbec.edublogs.org Use what talents you possess, for the woods would be silent if no birds sang except for the best. - Henry van Dyke Thu, 10 Dec 2009 02:10:56 +0000 http://wordpress.org/?v=2.8.2 en hourly 1 Hon Chemistry 12-7-09 Periodic Trends, Part 2 http://tskinnersbec.edublogs.org/2009/12/07/hon-chemistry-12-7-09-periodic-trends-part-2/ http://tskinnersbec.edublogs.org/2009/12/07/hon-chemistry-12-7-09-periodic-trends-part-2/#comments Tue, 08 Dec 2009 03:40:46 +0000 Ms. Skinner http://tskinnersbec.edublogs.org/?p=1344 HON CHEMISTRY: Happy Monday! Here’s the lecture on a couple more periodic trends – electron affinity, ionic radii, and valence electrons. We’ll for real finish the chapter tomorrow! Make a change on the syllabus – review tomorrow, pre-test on Wednesday, and TEST on Thursday.

Here’s the lecture from Tuesday on potential energy and the conservation of energy. Thanks for trusting me, Arthur! :)

Way too much craziness for me! How was net vertical force? Great job on the problems, but don’t forget things like terminal velocity and the why! And I still don’t know what’s so funny about a fish in an elevator?? :)

Lots of stuff to learn, but make sure you just don’t learn facts. Check out the videos in the VodPod collection below. You can find the cathode ray tube experiment, Rutherford’s gold foil experiment, and others. Be able to explain not only what they did in their experiments, but how Thompson and Rutherford used the experimental results to discover the electron, nucleus and protons. Hey, you’ll see a little of what they felt like tomorrow. Don’t forget your “atoms.” :)

What a lot of theory today! So the smallest thing that can be that thing is an atom. How do we know that? Well, we have to start at the beginning, and that’s Dalton’s Atomic Theory. Great job today comparing it with the Modern Atomic Theory. Keep those examples in mind when you’re studying for the test – especially when it comes to explaining those laws. :)
