I took out family season ticket 6 months ago and have visited 3 times during school holidays, attending both workshops on each occasion. I think the unique feature of this museum is that by attending the workshops, you experience science being taught in a comfortable setting where you can take it in. One doesn't always get this at other science events or fairs, that I have experienced. In others, I have found that the brightest or most confident children can take in the demonstration, by taking initiatives or huddling close or asking questions, and that the unengaged come away non-plussed. Not so at these workshops. The seating is equal. The lighting is appropriate. Everyone can see and hear. The speech is clear. The demonstrations are visual, visible and engaging. It is pitched so that there is new knowledge for most people. The leaders manage time well. Questions are handled affirmingly. The only disappointment we experienced was the Bubbles workshop, which was fun for the very young but had little to tell older children. We attended one workshop a second time (the sponsored talk on space / telescopes etc) and found it worthwhile coming back to it. All of us were fully engaged the second time because there was so much in it and the participation by children in turns was well-managed by the leader. Outdoors, the play area is very good and suits teens as well as little ones. The availability of a café, the freedom to bring a picnic, the proximity of the canal, the swans to feed and the view combine to make it a complete and enriching day out. Yes, one has to pay, but it's a non-profit making trust and the price tries to be gentle. I think, well done them.
