It proved to work very well at my school (Dartford Science and Technology College) where groups of mixed ages and across different key stages enjoyed what was for most, their first encounter with many of the instruments provided. The overwhelming sense of achievement was summed up by the unanimous and spontaneous applause the whole group erupted into at the end of the session. It provided an opportunity for mixed groups to work together and it was very interesting to watch the positive reactions of some of the more usually disaffected students. We only had time to sample a few of the many different techniques and exercises that can be tailored to suit different groups. The sessions are entertaining and will be something we hope to repeat at a later date.
