The BBC micro:bit is a pocket-sized computer that introduces students to how software and hardware work together. It has an LED light display, buttons, sensors and many input/output features that can be programmed.
Tape a Micro:bit (with appropriate protection) to the rocket to measure speed and upwards force.
Lesson must include drawing the circuits and then building them, in series and in parallel, before testing the light levels.
Use Morse Code from across the room to send a message
4 students can wave a sheet between the sender and receiver to simulate waves, and the receiver has to try and work out the message anyway
1 button flashes light in a dot signal, the other sends a dash signal, pressing both begins sending SOS
Possible Morse code through time: First have students send messages with light while waves are in between them, then to show technological advancements have them send the Morse code with radio waves. Then if possible they can use walkie talkies and the phonetic alphabet.
Put a sharp light over the light sensor to create stark shadows.
Use Micro:bits to measure the effects on speed on a car with/without tires trying to get up hill / drive down a track. Students can also test different car models/shapes.
3 lights in parallel, depending on the light level the Micro:bit will turn on 1, 2, 3, or none of the lights.
Can possibly adjust the room’s AC temperature by detecting the temperature outside.
The objective of the lesson is to use the Micro-bit to create an anemometer to measure the wind speed, which would reinforce their understanding on wind measurement.
