Class activities ideas for nervous system?

[michelangelo]

I am planning a class activity for 12th graders. The ideas I'm covering are involuntary reactions (particularly to stress and the release of endorphins) and parts of the brain.

For parts of the brain, I plan to do a charades like activity where certain groups will have to act out a word/ idea use only words, pictures actions etc which will correspond with the respective parts of the brain.

However, I do not have ideas for the involuntary responses to stress. Any ideas?

Well it's a school setting so that limits a lot. Most often, people react involuntary to physical threat or when they are surprised. Perhaps you can fake giving a quiz or a test randomly, or gear towards something more physically based but make sure not to cause any physical harm to your students!

Or maybe, you actually give a quiz and make them think its legit. Then when it's done tell them it was all a front to prove your point.
