Simple Harmonic Motion

For simple harmonic motion, which is periodic motion where there is a restoring force proportional to the displacement (like a spring, F = -kx), there are several videos.  These are for the basic derivation, small angle approximations, and how to solve initial conditions problems.  A fourth video is an application to a simple 1-D quantum mechanics problem, which shows where quantum numbers come from!  Have fun!

E&M - Circuit Analysis

In 4 Chem-Phys, we are looking at circuit analysis for resistor circuits.  We have our rules: Ohm's law, V = IR; Series and Parallel resistances (add in series, add reciprocals in parallel and flip over); and Kirchhoff's 2 rules (in series voltages add to that of the battery, in parallel the currents add to the total).  A video for applying all this is here.

Clean Tech Competition

There is a contest sponsored by the Center for Science Teaching and Learning, called the Clean Tech Competition. This one seems really interesting, where a team can identify a pollution problem in their community, or in any location in the world, and develop a clean energy solution for the problem.  If you are a finalist team, they will give a stipend to actually build the device, and you present your work.  There is a $15,000 prize.  Check out the site here.  Ms. Fitzpatrick will be the sponsor of a team if there is interest!!

Let Doc V know if you are interested.

Open-Ended Problem/Contest Resources

Just wanted to re-post the link to the article with info and links to helpful resources regarding the technical writing involved with presenting solutions to open-ended problems, as classes are working on project papers and teams are working on the COMAP contest.
