Soapbox, it is intended for GCSE students, but I went to the evening one in Manchester last year with DS1 (then 15) and DS2 (then 10); and lilibet and turnupthebass went with their DD (14) DS1 (also 10) and DS2 (7 or 8) - beety arranged for them all, except the youngest one, to be involved in a demonstration on stage which was great fun. (We all met beforehand for a pizza too - a mini mumsnet meetup in fact)
Last year's was about sound and involved musical instruments and recording equipment. It went completely over my head but the kids definitely learned from it!
Beety, thank you for pointing this out -- I've booked the Sadlers Wells one for dd1. Encouraged to hear Jan's ds enjoyed it aged 10, since dd1 is that age, but addicted to the Horrible Science books, so will hopefully cope with it and enjoy it.
In the same vein, can I draw attention to the wonderful free lectures offered by the Royal Institution . These are aimed at school groups, but individuals can attend too, and now don't need to book ahead. They also do good family activities sometimes during half terms.
Thanks so much for pointing this out -- dd1 had a fantastic time! She was on the edge of her seat, and hasn't stopped talking about it since -- was in fact explaining feedback loops to dh at 7.15 this morning over breakfast! Unfortunately we arrived too late to try and find you.
Presumably this is an annual thing, so we'll be watching out for it next year.
