General Physics

Physics 2000 web site at Colorado University. A very good, accessible site that covers a lot of different topics. Worth checking out!

Balancing Chemical Equations

http://misterguch.brinkster.net/eqnbalance.html. From Mr. Guch. The method described on this site is similar to both our textbook and the method I present in class.
Interactive Balancing Equations Tutorial. From Dr. Yue-Ling Wong at Wake Forest University. This is an excellent interactive web-based tutorial on balancing chemical equations. It uses methods similar to what was taught in class, in the textbook, and in the web site above.

Word Equations Practice sheet. From Mr. Guch. A practice worksheet with answers.
Interactive Balancing Equations Exercises. From Dr. Yue-Ling Wong at Wake Forest University. This is a collection of practice problems for balancing chemical equations

Overview of chemical bonding, both ionic and covalent. This page from Anthony Carpi (site is hosted at the City University of New York) includes a couple links to some very nice Flash animations on ionic and covalent bonding, as does the updated version of the page.
An online quiz on chemical bonding. Try it... I promise I'm not grading it!

Chemical Reaction Types. From Mr. Guch. Note that on this web page, the author lists six types of reactions. (Acid-Base is listed as a separate type: later, we will study acid-base as a special case of the double-displacement reaction.)
Chemical Reaction Types. From Utah State Office of Education. On this web page, the author lists only four types of reactions. (Combustion is omitted.)

Tutorial on Isotopes and Nuclear decay (Physics 2000 site at Colorado University). Note that the format for nuclide notation shown on the CU site differs from what is taught in Mr. Y’s class (and in the textbook used at WHS). Both are acceptable.

This applet shows some of the various stable and unstable isotopes. For unstable isotopes, it shows (very nicely) what they decay into.

Tutorial on Nuclear Decay (Australia)
Applet that shows effect of decay on number of unstable nuclei. (Half life demo)
Video of Nuclear Fission and Chain Reaction (time: 0:24)
Animated GIF of Nuclear Fission (short)
Animated GIF of a Chain Reaction (short)
Video of a lab demo with ping-pong balls of a chain reaction (time: 1:16)
Animated GIF of Nuclear Fusion (short)
Video of first ever hydrogen bomb test in the USA. (time: 2:18)
Video project on the Science Behind the Atomic Bomb (time: 19:06) by Nigel Fong. This video covers a LOT of material, and Mr. Fong speaks with a bit of an accent, but the information is pretty good.

From Dr. Dan Russell, PhD at Kettering University, Flint, MI. http://www.kettering.edu/~drussell/demos.html. Many demonstrations and visualizations for waves.
From the Nondestructive Testing Resource Center: some interesting flash animations showing how transverse and longitudinal waves move through matter.
Applet showing the superposition principle of waves. (National Taiwan Normal University) This is a superb Java applet that shows how the superposition of waves works. It also allows the user to modify the wave characteristics so that you can see how the beat phenomenon is produced.

The principle of Quantum Superposition is a little different from the superposition of waves. This video discusses quantum superposition.

This applet is used to show the Doppler effect. (Davidson University) It’s simple and elegant, and does what images on paper cannot show: the movement aspect of the Doppler effect.
This video discusses the particle-wave duality of electrons rather nicely.
This Microsoft Excel document shows the superposition wave forms for the fundamental and all overtones for several musical instruments.
