## “Oh, you think you have a rule? See if you can wreck it.”

I'm noticing that more kids are gaining confidence in looking for patterns, forming hypotheses and then seeing if they can make the hypothesis fail. The phrase that seems to be gaining ground when it comes to hypothesis testing is "wreck it" – as in, "Oh, you think you have a rule? See if you can wreck it."

There are two things I love about this:

- The phrase "see if you can wreck it," and the toddler-knocking-down-a-tower-of-blocks spirit of destruction it conveys.
- The fact that
*you*are supposed to wreck*your own*conjecture. Your conjecture isn't something you're supposed to*protect*from your peers and your teacher as though it were an extension of your ego. It's*supposed*to get wrecked. That's okay! In fact,*you're*supposed to wreck it.

**BTW**. When David Cox finds a free moment to blog, he makes it count. Now he's linked up this spherical Voronoi diagram that shows every airport in the world and the regions of points that are closer to them than every other airport. "Instead of having to teach things like perpendicular bisectors and systems of equations," he says, "I just wish we could do things like this."

Of course you need perpendicular bisectors to *make* a Voronoi diagram, so David's in luck.
