Hi, I am really struggling and wondered whether anyone could help me. May I apologise in advance for any spelling errors - I am typing on my Mum's computer and some of the keys seem to be sticking. Anyway, we are going to be learning about "gases" and "changing state". I have looked into Eureka and Magna but neither seem relevant. I am in the north of the UK about an hour from Leeds, two hours Manchester, 90 minutes Sheffield. I really wouldn't want to travel much longer than this - does anyone have any suggestions?
