This kit explores simple structures and mechanisms such as wheels axles, hinges, cranks, cams and linkages. The kit comes complete with photocopiable work sheets, teachers notes and enough TechCard and mechanical components to construct twenty models - two each of ten different designs.
The Build-it Kit models include a balloon or sail powered vehicle, three different pull-cord powered fairground rides, a working windmill, a draw bridge, scales and a crane as well as a flying bumble bee and hungry frog!
The basis of the TechCard system is a set of pre-cut, scored and punched card components that are simply folded and glued to form an infinitely variable range of girders, beams and bases. The overall dimensions and grid of pre-punched holes make accurate model building remarkably easy, making TechCard an ideal system for developing model making skills, 'design and make' and prototyping.
The TechCard structural components are made from 100% recycled material making it a uniquely affordable and environmentally responsible building system. TechCard components are easily customized by cutting and scoring with scissors or a craft knife and glued together with ordinary PVA glue which is safe and quick to use. The TechCard structural elements are complemented by a complete range of mechanical components including wheels, axles, pulleys and gears as well as pneumatic systems, propellers and much more.
