This year students from stage 3 participated in the NSW Aeronautical Velocity Challenge – a competition designed to encourage STEM skills across bottle rockets and model planes for all ages and education sectors.
The winners were getting upwards of 125m in distance, which is very impressive. Mt Ousley PS has spent quite some time over the past few years using rocketry as a way to hook kids into loving science, maths and all things space. So it was great to join in this event.
While model engine rockets have a place in my program after visits to the Honeywell Educators@Spacecamp program, I also love bottle rockets for the relative simplicity of teaching elements of design, maths and physics. With variables including fin and nose cone design, rocket mass and balance and air/water fuel balance, the opportunity arises for many iterations and tests to obtain maximum flight.
Our team ran with a simple 1.2L bottle, foam core fins, a weighted nose cone and a decorative mission patch which is a terrific way to incorporate elements of human endeavour, art and symbolism. Not the most evolutionary but a sound starting point for their first competition.
One of the best aspects of sharing in these days is getting to see how other teams approach the design process. Many primary and secondary schools were using 3D printers to design fins and nose cones. There were also quite a few jigs and spacers being used to carefully hot glue on the various components. Our team came away excitedly planning how they might approach future builds.
When it came to what mattered – the launches, they were a mix of long and impressive flight, some mid air collapses and a few with wayward direction due to design flaws with balance, fins, weight etc. Rocketry is a truly engaging STEM activity that offers wonderful design opportunities and a visible result as to success or otherwise.
Of course it’s always fun to launch, fire or blast a rocket and both teachers and students enjoy the experience. Importantly rocketry can be done safely with some basic attention to cutting and tool instruction and well considered launch and recovery procedures. Always learning!
