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!"
