The Physics Classroom: Refraction of Light - Sep 16, 2010
Use this simulation to explore how light waves bend when they go from one medium into another, like from air into water.
Konigsberg Bridge - Sep 1, 2010
If you enjoy solving puzzles, try the seven bridges challenge.
Splash (fluid mechanics) - Aug 16, 2010
Investigate splashes by dropping different-sized objects into containers of water. Also, you can squeeze drops out of a medicine dropper to make splashes on hard surfaces or on water or milk. (Be sure to do this activity with an adult.) To find out what happens if you drop a half-brick into water, see the photograph at the bottom of Splash (fluid mechanics).
Water on the Move - Aug 1, 2010
Using the instructions on Water on the Move, you can create a model with everyday materials that shows how the water moves as a wave passes by. To visualize the movement of all the water in a wave, see the third animation on this Kettering University page.
Soap Bubbles - Jul 16, 2010
Playing with soap bubbles can be fun and educational for people of all ages.
Investigation 4 - Erosion - Jul 1, 2010
The Doppler Effect and Sonic Booms - Jun 16, 2010
Check out The Doppler Effect and Sonic Booms for animations of the sound source moving at various factions of the speed of sound, with related background information and lots of interesting images. For a related simulation, where you control the speed of a supersonic bug, see NASA's Interactive Sound Waves.
Build Your Own Star - Jun 1, 2010
See how the initial mass and composition of a new star will determine that star's fate by Building Your Own Star. Simply enter your desired parameters and watch as the star grows from a cloud of gas and dust and changes over time, condensing billions of years into a minute.
Interactive Plasma Physics Education Experience - May 16, 2010
A tokamak can control plasma using magnetic fields, and it is the most promising design for a nuclear fusion reactor. Check out these Virtual Tokamak applets to learn how magnetic fields act upon plasma and how to start a fusion reaction. (See the help page first-- it explains the simulations as well as the concepts behind fusion reactors.)
Descent to the Mid-Atlantic Ridge - May 1, 2010
At Descent to the Mid-Atlantic Ridge, from the University of California at San Diego, you can follow a submarine descent to the mid-Atlantic Ridge. Also, with this colorful computer activity from the Monterey Institute, you can learn the names and locations of mid-ocean ridges and how distance from the ridges is related to the age of oceanic crust.
