Autumn gets serious now.

Dark.

Dark.

More dark.

Here's something you can do with your children to help them see the world. You need nothing but normal vision and a clear sky.

*Find Polaris, the North Star, at 7 P.M. It's not as bright as you might think, but it's there, and it's special, as your child can discover in just an evening.

*Find Aldebaran, the Eye of the Bull, the Eye of Revelation. 5,000 years ago it rose in March, now it rises in November. This, of course, our child cannot see, so do not trouble her with it.

What she can see, though, is that the eye of the bull moves across the evening sky. In an hour or so, it will have creeped a bit across the sky, following the path of our closest star--she might have noticed even if the adults around her do not.

Now ask her to look at the North Star--it sits stubbornly in its spot, the universe seemingly rotating around it.

She might ask why, she might not.

If she doesn't, don't push it.

She's already gotten more science education in an hour than she may get in my classroom in a week. Or two.

Science starts with observation, and it starts outside. Trying to do astronomy inside is like trying to make gold from tin.

Alchemists were seriously bright people earnestly trying to make a precious metal for all the wrong reasons. Alchemy has since been discredited.

Science teachers may be headed for the same fate.
