Successful energy absorbing Castle roof: Design +Physics + Humanities/ I&S: MYP Design / STEM / IDU

This is slow motion video footage a successful foamboard roof design made to resist the impact of a 25mm diameter steel ball bearing dropped from approximately 11 metres onto a 'castle' roof. The design task here was to use foamboard and hot glue to create an energy absorbing structure to resist or deflect the kinetic energy of the steel ball bearing projectile. In this case a flat honeycomb roof design that was not glued onto the walls was used and this proved effective as the structure collapsed and deformed to grip the projectile and the straight walls underneath the roof acted as a spring to disperse and absorb the energy. The energy was redirected back upwards when the whole roof 'bounced' back into the air. The 'egg soldier' character shown in the centre was created to add motivation and interest as it gave the students something specific to 'hit or miss'.
