Area Builder gives students the opportunity to build any shape and explore the relationship between the area of a shape and the length of its perimeter. The “Game Screen” contains two kinds of challenges: Build a shape and Find the area. There are different levels of increasing difficulty. The teacher notes give...

With this simulation students can move objects on a seesaw to learn about balance and test what they have learned by trying the Balance Challenge game.

Sample learning objectives include:

*Predict how objects of various masses can be used to make a plank balance.

*Predict how changing the...

This simulation allows students to arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. They can plot equipotential lines, discover their relationship to the electric field and create models of dipoles, capacitors, and more!

Sample Learning...

This simulation allows students to build circuits with capacitors, inductors, resistors and AC or DC voltage sources, and investigate current and voltage.

Sample Learning Objectives include: *Build circuits from circuit diagrams. *Use an ammeter and voltmeter to take readings in circuits. *Discuss basic...

Circular motion: ball on tether released (vertical plane)

Circular motion: horizontal ball in a hoop (Tim holding)

Circular motion: vertical ball in hoop (Tim holding)

This simulation allows students to use an air hockey table to investigate simple collisions in 1D and more complex collisions in 2D. Students can experiment with the number of discs, masses, initial conditions, and can vary the elasticity and see how the total momentum and kinetic energy changes during collisions...

Collisions: inelastic collision top view

Collisions: inelastic little spin

Collisions: oblique collision

Collisions: rebound (v-t)

Collision: small mass into large mass

Collisions: equal mass straight (x-t)
