The Physics Classroom
Includes a physics tutorial, a multimedia physics studio, interactive Shockwave files & physics &
direction, & practice vector addition.

Multimedia Physics Studio
Is physics difficult for you to visualize? Do you need to see it to understand it? Then visit the
Physics Learning Site
Includes the basics, vectors, vectors & angles, visualizing motion, uniform acceleration,
projectile motion, & relative velocity.

Yahoo Physics
Links to everything you ever wanted to know about physics.

Amusement Park Physics
How do physics laws affect amusement park ride design? In this exhibit, you'll have a chance to
find out by designing your own roller coaster. You can also experiment with bumper car
collisions.

Circles of Light: The Mathematics of Rainbows
This lab includes a good explanation of reflection & refraction.

Visual Physics
Save your money! Don't buy the simulation software. You can do a lot of simulations from this
site.

Tables of Units of Measurement
From the National Institute of Standards & Technology

Boil Water with Shockwave
Run this experiment -- changing thewater amount, the starting water temperature, & the heating
power. Guess how long it will take to boil the water.

Matter
Learn about the structures & properties of the four states of matter.

Electricity & Magnetism
Learn about static charge, moving charge, voltage, resistance, current, & the properties of
magnets.
