Mrs. Kelly from Stemworks today set Year 5s an engineering challenge: to make a K’nex structure that would lift a block at least 10cm vertically in the air.  Teams of two set off enthusiastically and some amazing structures emerged, all using pulleys to lift a ‘heavy’ block with a small force.  The finished creations were judged with William and Rory going through to represent the school in April’s final.  Amy, Bonnie, Archie and Miles all had a special mention for the creativity of their designs.  Well done, everyone!
