We didn’t plan on running any holiday programmes in March this year, but a group of parents requested for it, so we came up with the idea of combining water rockets with micro:bits. The micro:bit is used to measure flight acceleration, and can also be used to measure flight time.
In the morning, the kids learned about how rockets work and tested different stabilizing fins designs. Then after lunch, they constructed their rocket, programmed the micro:bits, and drop-tested it before the actual launch. We didn’t have time during this one-day programme for everyone to construct their own launcher, so we used one that we’ve built the day before.
