Brush Monster Class Kit

Brush Monster Class Kit

A cross-curricular STEM class kit for 30 pupils working in groups of 3 to design, build and test vibrating brush monsters.

Pupils will apply their knowledge of simple series circuits to make a working model. The pupils will construct a switched motor circuit which rotates an offset weight, causing vibrations.

They will mount their circuit on a dustpan brush, so that the vibrations are transmitted down the bristles, causing the brush to scuttle across the floor. The brushes are then decorated and raced. Here is a quote from a teacher: “The activity was fantastic and the children definitely bought into the fun, purpose and challenge of the session. What an excellent idea from such simple components!” Created by mechanical engineer Caroline Alliston. Supporting literature includes a lesson plan, PowerPoint, pupil worksheet and ‘how to’ blog.
