Thursday 11th November 2010 – Year Five Moving Toys

Filed under: DT,Year 5 @ 7:58 am

Year Five have embarked on a challenging DT project, designing and constructing moving toys using cams.  Today, we were creating prototypes to gain a clearer understanding of how these mechanisms work.  In pairs, children had to construct a cardboard frame, and make an off-centre cam, a snail cam, and a pear-shaped cam out of thick cardboard.  These cams needed attaching to a drive shaft in order to convert circular motion to linear motion.  We will be using our learning from today to help with the designing of our final products.
