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: large mass into small mass from above

Collisions: oblique collision

Collisions: rebound (v-t)

Collision: small mass into large mass

Collisions: two equal mass head on above (drift)

Collisions: equal mass straight (x-t)

This activity from Subtangent is based on the four colour theory, which is used by mapmakers. Resources include examples of colouring maps correctly, together with additional challenges, which cover a range of ability, for students to try themselves. Solutions for the challenges are also provided.

This excel workbook contains a series of sheets to help students explore different types of composite functions including linear, quadratic and reciprocal functions.

The first sheet allows students to input different...

With this simulation, students build an understanding of solution concentration by varying amounts of solute, solvent, and solution. Experimenting with several different chemicals in solid and concentrated solution form, students can develop qualitative and quantitative relationships.
