Got a Giant Evolution Timeline? Great. Then you've probably seen the scavenger hunt questions on the back.
Yesterday I wrote up a bunch more questions for someone who asked about them, and here they are for you! Just print them out, hand them to your kids, and see what happens. (Keep the answers under your hat though.)
