Life Science
Tell the students that when they are told to go, they will:
• Pick up a red chip at either “Lung Station.”
• Run to the “Heart Station.”
• Make a loop around the room towards the “Organ Station.”
• Drop off the red chip and pick up a blue chip at the “Organ Station.”
• Run back to the “Heart Station.”
• Then run to the “Lung Station,” and drop off the blue chip in the bucket.
• Pick up a new red chip, and start the course all over again.
• After the students have a few minutes to run through the course, bring them back together for a brief
discussion.
