As part of our design and technology this term we are looking at a range of mechanisms, such as CAMs, pulleys and cranks, in order to make our own moving toy. Before the children can begin making their own designs we need to learn about the different mechanisms. In today’s lesson we looked further into each one, by thinking about how they work, why they might be useful in a toy and the movement that they make.
In order to understand this properly and put them into their own designs we followed some instructions to make prototypes that had one or more of these mechanisms. The whole class worked really hard in their groups and really thought about what the instructions were asking of them, as we have been looking at this in English. They discussed what mechanisms their prototypes had and how they knew, based on what we had learnt earlier in the lesson. We will be continuing to look at and make the different mechanisms during the week before planning our own designs.
