CPU worksheet

This worksheet is aimed at GCSE students aged 14 - 16. It is best used as a plenary activity at the end of the unit, after the students have been introduced to the fetch-decode-execute cycle and simple assembly code. Alternatively, the resource could be used as a home-learning task or an end of topic assessment....

Fetch-decode-execute-plot

This is an unplugged resource to simulate the fetch-decode-execute cycle in a processor. It is a frantic starter activity aimed at students aged 17-18.

Fireworks

An ideal lesson plan for the lead up to fireworks night! This is about making sparkles flash with random intervals and colours. It can also be made more difficult by using LDRs.

Christmas tree

An ideal plan for a Christmas themed coding lesson! This plan involves a Christmas tree that has sparkles lighting up as the baubles, but it is also possible to use other Christmas-related ideas (for example Christmas cards) that have the same code.

Constellation

Using sparkles to light the night sky. It is possible to make them ‘twinkle’ or use an LDR so they only light up in the dark.

Dice

The dice uses sparkles and a code to make them flash randomly. What is the probability of the same numbers being picked and does that mean it is truly random? It is also relevant here to think about nets and dice shape.

Lighthouse

This uses a motor, a sparkle and a marble to imitate a lighthouse. It can be made harder by incorporating LDRs.
