This is a game I created to get kids up and moving while learning! I teach them the motions to go along with each organelle's function as a whole class, then when I am satisfied everyone has them all down, cards are distributed and we go outside. I usually have a whistle with me too to use to corral them at the end.
I have each organelle printed on a different color paper to make it easy to tell who should be doing what when they are running around.
**I have a version of this for Human Body systems too, so be on the lookout for that!**
