Darcy Cowan at Sci Blogs has a 28 question science literacy test. Unfortunately, too many of the questions confuse statistics for science*, so it’s more about statistical literacy than it is about science, but it’s still worth a few of your precious minutes.
For what it’s worth, I got 25 out of 28.

* a reliance on induction by enumeration, without reference to causality, about which mere statistics is blind.
