During Special Week, curious scientists in Class 3 built rockets from kits, customising the aesthetic design and choosing the ignition mechanism for the potassium nitrate rocket motors, either using a classic fuse or an electric instant ignition. Students also had to test and confirm that the parachutes functioned correctly before heading to the school fields to launch them. All rockets fired up successfully, but despite successful testing only half deployed their parachutes on the way down, with some returning to the earth fairly abruptly. This activity was an exciting problem solving and teamwork opportunity for Roseans, also utilising their mathematical skills to understand how trigonometry can be used to estimate the height reached by the rockets. A brilliant activity for all involved for a taste of the engineering process from design to construction and from test to deployment.
