Notes for teachers which can be adapted to support Computing projects from Key Stage 2 through to Key Stage 5. The pdf document “Rocket Science with STOMP and Scratch” derives the mathematics behind projectile motion using a very simple numerical example which is explored with spreadsheets and the free GeoGebra software, leading to a simple graphical animation in Scratch. More sophisticated methods using basic algebra and trigonometry are explained and explored. The ideas can be built into a variety of projects such as a simulated golf game in Scratch. The ideas bring together historical developments such as Galileo’s theories and Babbage’s mechanical computers in a cross-curricular exploration based on science experiments and mathematical theory. Ardent rocketeers can also design and build their own air-rockets in D&T. The supporting resources include Excel, GeoGebra, Scratch and Tracker files as well as video clips.
