Design and build a wind powered garden decoration/whirligig

A resource I designed and made for year nine or ten product design. Students study the basics of motion, mechanisms and force to produce a crank driven garden decoration. It isn’t a heavily prescriptive resource but offers opportunity for interpretation, differentiation and varying degrees of sophistication in terms of outcome. It contains lots of mini focused practical tasks to produce the key components for a complete, functioning garden whirligig. It contains a wealth of information to help analyze existing products, conceptualize and develop a working solution. I’ve also attached a complete production plan for the whirligig shown in the video.
