4. Organs Activity
What do you know about the body’s internal and external parts and how they work together?
In groups of 2-3 make a list of all the body parts that you can think of, both internal and external. Write each one on a post-it. Try to figure out how they work together to keep you alive.
Once your group has decided the pattern, create a concept map showing how the body parts are linked.
