This brief activity uses false-colour images of the Columbia glacier to introduce the idea of using sequences of satellite images to monitor change and focuses on the selection of appropriate data for an investigation.
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.
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.
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.
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.
This uses a motor, a sparkle and a marble to imitate a lighthouse. It can be made harder by incorporating LDRs.
Very simply, this involves making sparkles flash. The challenge is to work out how long a ‘dot’ and a ‘dash’ are, and to successfully code a message in Morse code.
Using LDRs and sparkles, the student learns how to code a nightlight coming on only once it gets dark. Digital switches can also be incorporated into this.
Ideal for a Halloween-themed coding lesson! Using sparkles to mirror a candle in a pumpkin – can you make it flicker or only come on once it’s dark?
Ideal for a Halloween-themed coding lesson! Using sparkles to imitate eyes in a portrait – but can be made harder using LDRs or making the lights fade in and out.
