As the year 9’s progress with their mp3 speaker project they have turned their attention to the design of the speaker grill. Using an approach called design rules students were asked to come up with a range of design based on a restricted design vocabulary i.e. A set of design rules.  In one set of ideas this was limiting the design to using only straight lines and circles for example. The purpose of the exercise is to generate a range of ideas quickly and to reflect on whether these limitations help or hinder creativity. Here are some of the results for you to judge for yourself.
