Last week was really fun and really, really busy. We would run off to dinner at about 5, get to the church before 6, get Jet off with his class, and then Tonya, John, and I would set up the classroom and then run three sets of at least two experiments every single evening.
I'll admit that this was the first time I'd ever heard of a science portion to a Vacation Bible School curriculum. And I think all of us really wanted to pull it off and fascinate the kids and make it work so that the parents would be good with us having something like that again. I think it might have worked, as at least five sets of parents said that their kids were happily doing experiments at home to show them and really wanted to come each day in order to do the surprise experiment of the day. *grin*
I think the best one was the "growing your own 'coral reef'", which we did explain wasn't a *real* coral reef, it was a bunch of chemicals, water, and salt that would let salt crystals grow out of a charcoal (we could have used sponge or concrete... weird) base, which would absorb the mix and then wick it up to the "coral". The results were pretty spectacular.
( Here's a small picture of one of them. )
