Smarter Than a 5th-Grader?

The television show Are You Smarter Than a 5th Grader? pits adult contestants against fifth-grade students to see how much adults really know about the subject matter covered in that grade.

The students on the show can help the adult contestants when they're stumped on the answers and their quest to win the top prize of a million dollars. Adult contestants can make use of three features: peek, in which they can look at the student's answer and decide if they will use it; copy, in which they have to use the child's answer; and save, in which the contestant's answer is incorrect and the student's is correct and the student saves the day.

Here is WebMD's version called "Are You Smarter Than a Fifth-Grader in Health?" We talked to teachers, skimmed fifth-grade health texts, and peeked online at fifth-grade curricula to put together our quiz.

See how you fare. Answers are at the bottom. Test anxiety? Relax. You get one "save," but sorry, no "peeks" or "copies" in this online version of the game.
