We had a science session at the library which I ran.. I had a few ideas ready but decided to wing it depending on who came along. Initially a few children started a game of chess, others joined in helping with advice on tactics etc, then when that finished I offered the science idea.
It went well (these things don’t always)
I got each child to be an H or an O and then we had O2 molecules or H2 molecules. Then we did H2O molecules with the H children holding hands with the O children and acting out how things worked. We talked about elements and molecules and the periodic table and then we built some molecules with a kit I have.
This led on to talking about carbon and carbon chains and organic chemistry, and diamonds and graphite. The session went really quickly and the kids were all engaged.
A couple of friends then came back to play, but we also did a bit of algebra because they’ve been doing some at home and so have we, so the kids showed each other (and parents) what sort of methods they’d been looking at. We’d been looking at working out the nth term. They’d be looking more at factors, so it was a good swap of ideas.
There was then lots of playmobil play, and some time playing in the garden as well.
