17. What I Want to Know About Sharks      10 Points
Most of the time someone teaches you something, you wonder about the other things that they didn't tell you.  This activity is to help you design an experiment to find out something about sharks you haven't learned yet.  The point is NOT to actually do the experiment, so you don't have to worry about how much money you need to spend or what equipment you would need.  Just think about something you would like to know about sharks that you could find out by doing an experiment.  Use the What I Want to Know About Sharks Lab found at:
