Right, number one. I thought this one sounded nice: there'd be lots of activity and it doesn't need too much in the way of equipment.Yes, that's true, but don't you think it's a bit risky to get a group of eight-year-olds pushing each other around a classroom like that?Someone could get hurt. No, I don't like the sound of that one at all! Maybe you're right.What about number two, with the paperclips? It sounds tame enough.Yes, a bit too tame if you ask me. I think it needs to be something a bit more active and interesting than that, don't you?Yes, I suppose you're right. We won't get a very good mark if the children don't actually enjoy the experiments,and I suppose we could turn them off science for good! Well, what about the next one, number three?Now, I quite like the idea of this one.Yes, so do I, but I seem to remember when we did it at high school we had to wait up to a fortnight before we saw any halfway decent results.
