In this activity, students consider how engineers build the hull of lifeboats so that they are light and strong. Students are challenged to construct a beam using cheese crackers, wafers, paperclips, bridge supports. They can consider building beams using a wider range of materials such as aluminium or wood beam theory could be introduced, testing how a given weight would deflect each beam, and how changing the depth or section of the beam alters its load carrying capacity and deflection characteristics.
