Year 8 took part in a bridge building challenge for the recent CAD. They had to design and make a structure to span a 400mm gap using nothing more than 100 lolly sticks and hot melt glue. The structure had to be self supporting and support a 3KG mass. In the case of a tie break the winner would be the one that used the least amount of materials.
The students worked in groups for the duration of the day and produced some great results, mostly supporting the 3KG.
