Quantitative Analysis for Kids

My Oldest:  How many licks does it take to get to the center of a Tootsie Pop?

His Buddy:  170, My brother tried it.  It’s 170.   (pause)  But I told him he needed to do it again to make sure.

My Oldest:  Yeah, we should do it a lot of times and take the average.

And hopefully the standard deviation, so they can report the error in their measurement!  Fourth graders concerned about certainty in their measurements?  It’s an analytical chemist’s dream!
