In this activity, Arnold is missing organs from four major body systems. It’s your job to put them back.
On the activity screen, you’ll see an outline of Arnold’s body on the left, and a whole bunch of organs on the right.
When you hit the Play button, the name of an organ system will appear at the bottom of the screen. Your job is to get all of the organs that belong in that system into the body.
But be careful! If you drag in an organ that doesn’t belong, all the organs pop out, and you have to start over!
