It was a great kit to do with a large number of classes coming through – I have it for another week and have two classes using it per day. I’m doing slightly different things for the younger kids – more discussion, wonderings and really honing in on developing their observational skills. The kids were really engaged with it – I was surprised that hardly any of them had seen a Jacob’s Ladder! That’s a classic toy I would’ve thought. Anyway, great stuff and thanks.
