Year 5 have been working hard this term designing star catchers. They came up with some designs and then explored mechanical components and how they worked. Most opted for their design to include a pneumatic element. They carefully drew their final design making sure all drawings were clear had enough detail so they could build them. Then came the fun part of making them. Afterwards the machines were evaluated according to how effective the structure was, how attractive it was, how sturdy was it and finally was it fit for purpose.
