In this challenge, you must successfully cross a river and land as close to the target on the opposite shore as possible.  You will have two minutes to successfully land as many boats as possible.

Here is an html5 virtual environment to look at flow rate, continuity of flow, energy conservation and Bernoulli's principle.  All of these can be taught by having students examine the behavior of water in an ideal siphon.  I suggest having students compare this behavior to real siphons after they finish the virtual lab.

These look like really good simulations.  Thank you for sharing.

I have been working to create virtual environments for my students to use in AP Physics 2.  I have just finished one dealing with the distribution of different wavelengths of light for stars of different temperatures.  Just click the star to change to a different temperature star.

Here is an html 5 simulation dealing with monatomic gases in a piston.  The simulation will allow you to examine isothermal, isobaric, isochoric, and adiabatic processes.  It will also allow you to see how mass and temperature affect the average velocity of the atoms in the gas.

I still need to run tests to the program and make sure there are no hidden bugs, but I figured I would put out the link to this program now so that I can get feedback while I am still working on the finishing touches.  So if you see any problems or things that could be enhanced, leave comment in the space below this post.

Just did a complete rewrite of my magnetic field from a wire simulation to turn it from a qualitative lab only to a lab in which students can study the field qualitatively or quantitatively.  

Students can change amount of current, the location of the probe, and the direction of the current.

All comments and suggestions are welcome.

An html5 environment that allows students to examine the relative motion of a toy boat crossing a waterway with a current.  Students can change the width of the river, the speed of the boat, the speed of the current, and the angle at which the boat is launched.

A virtual environment where you can look at the acceleration of a metal bar that is carrying a current through a magnetic field.  The mass of the bar, the resistance of the bar, the voltage and direction of the battery making the current, the strength and direction of the magnetic field, and the distance between the rails can all be varied.

+Peter Vogel, I agree about the fraction of a mm.  I was silly to display the rail separation that exactly.  I don't want the timer to stop automatically because I feel this will make the students less active.  I want them to be focused on the rate of motion of the bar and I feel that having them trying to stop the timer on their own will better accomplish this.  

+Colin Mckay, I use the randomly generated values instead of a slider because I want to make sure that every student does the lab on their own (especially if I assign it as homework) and that they don't just copy the numbers from someone else.  When the program loads, numbers for all the parameters are randomly generated and there is no way any two students are going to have the same data.  I wish I didn't have to do this, but I have seen too many students over the years try to take the easy way out when doing assignments and I want to make it so the easiest way is the right way.

I just finished an html5 game where students learn about the different stages of an internal combustion engine.  They must open and close valves at the proper times and fire their spark plug at just the right moment to speed the engine up.  Each cycle they go through will speed the pace of the engine.

I have tested the program pretty thoroughly, but I would love to have others run through it and let me know if they run across issues.  I have had a few other people run through it and the record for the most cycles is 12.  My personal best is 2.

What courses or physics topics would you like to see on the internet?

I want to make a physics course series. it will be video and other resources (like animations, simulations apps, and games). It will be  on topics that don't  already have a lot of  resources, and with people in need for them.
I'm a theoretical physics graduate student in my last year of graduate school.

In our high school district we do a lower-level introductory physics, AP Physics 1 and 2, and AP Physics C (calculus-based mechanics and E&M).  We are an iPad district, so anything we use has to be HTML5 browser-based.

Maybe pick something that you think you can do really really well?  The simpler and clearer the better.  I suspect you might be better off focusing on making one or two great resources, rather than a site full of mediocre ones.

Here is an offshoot of the gas law lab.  It shows students the Maxwell Distribution of Speeds for different gases at different temperatures.  Students can store up to 6 plots on the screen at a time so they can compare one gas to another or one temperature to another.

PURPOSE OF FOURIER TRANSFORMS.....
(1) Why sin(30) = 1/2 ?
(2) i ^ 2 = -1 = rotation by 180°
(3) Transpose [A] = Rotation by 180.
(4) Diagonal of a matrix = Its axis of rotation.
(5) Why A x B = ABsin( )??
(6) Why Log(A x B) = Log(A) + Log(B) ???
(7) What is the purpose of curl and divergence??
(8) Purpose of differential equations.
