I saw a great article over on Forbes by Chad Orzel, a physics professor and author. He reported on the idea of not just talking about science with kids, but actually doing science with your kids. He gives the example of his daughter who read that a person is about 1% taller in the morning than in the evening…so they experimented and measured Chad a.m. and p.m. And guess what! It’s true! They were able to determine a 0.73% difference. He comments,

I mention this not because it’s a particularly impressive experimental achievement, but precisely because it’s not a particularly impressive experimental achievement. It needed a tape measure, a stepstool, and remembering to re-measure my height the next morning. But both of the kids were really excited by the whole idea.

It’s just one example of taking opportunities to measure and experiment with simple things. Noted–a “weird science facts” book for 7 year olds can be helpful. See the full article.
