Boys and girls in Years 4 and 5 were asked to design a new piece of apparatus that could assist in medical surgery for organ transplant procedures.

Children had a budget of 150 Faraday to purchase resources for their structures including wood, plastic, adhesives and craft decorations. Wood, as well as bolts and string were classed as limited resources, so teams had to bear this in mind when designing their pieces.

By the afternoon, teams built their apparatus and were able to practise using them in a surgical theatre-like scenario. Using a clothed-screen with one access hole, children tested how their new tools were easily (or not so easily) inserted, assessed how successful the grip mechanisms worked in taking hold of two different sized balls (used to represent a heart and kidney), and attempted to remove the balls through the same hole.
