Two things I learnt, a) Scratch is much more fun if you have sound on b) if you use the drawing example from session 1 it might be better to start with a Scratch base where the default sprite is a pencil, rather than the cat.
I think as a "taster" you need to combine some element of demoing what is possible with some simple DIY things. Without a demo of what is possible I don't think there will be a motivation to go and try it at home.
Have fun and ask if anything is not clear.
I saw Jim's blog post. It's really useful. Thanks also for your additional tips. The point about demo plus DIY is great.
I'll let you know how we get on.
