Since I started teaching at Florida Gulf Coast University I've made all my students take a science pre-test. I don't count it towards the students' grades, but it helps me see how much science and math education they have had and remembered... and what I need to catch them up on! Sometimes at the end of the semester I'll give it again for a grade. Anyway, I'm putting the test here on the web so other people can try it themselves, or copy it and use it for their own teaching purposes. Some of the inspiration for and answers to the test can be found in a post on my personal blog: http://jimbodouglass.blogspot.com/2009/12/practical-science-stuff-to-know.html
