Getting a Grip on It

Have you ever stayed in the bath or pool so long that your fingers turned wrinkly? Why does this weird thing happen? Scientists asked people with dry fingers and people with wet, wrinkly fingers to pick up and move wet and dry marbles. The wrinkly-fingered folks could move 9 marbles in the time the dry-fingered folks could move just 8. Long ago, these puckered fingers may have helped cavemen catch fish more easily. As for you, it'll help you grab that rubber ducky.

Read the story. Talk through the numbers. Kids do best when you do the math together!
