This cross curricular activity includes science content from Year Four of the primary curriculum. It introduces programming and control, linked to the outside world through sensors - in this case, the computer's built-in microphone or a peripheral microphone. Programs are written using Scratch (online or offline)...

Climate Change: It’s In Our Hands is a classroom-based board game which helps pupils in upper key stage two (7 to 11 years) explore and discuss the complexities of the global climate emergency and test out possible strategies to mitigate it.

Over four rounds, groups of pupils invest in actions that...

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...

This series of interactive excel sheets investigate models involving collisions.

The first sheet simulates two particles colliding. Initial velocity, mass and resulting velocity of the two particles can be set, or a...

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)

In this simulation, students create a rainbow by mixing red, green, and blue light. They change the wavelength of a monochromatic beam or filter white light and can view the light as a solid beam, or see the individual photons.

Learning objectives could include:

*Determine what colour the person sees...

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 series of interactive excel sheets aimed at Year Four students look at comparing and ordering numbers. Answers can be checked each time and new questions generated at the click of a button.

In the first sheet...
