I have fun hands-on first day activities for all the other science I teach; I have yet to find something similar for my A & P class. I just want them to be doing, not listening to the 'expectations of the course'. These first days are often shortened periods; I'm searching for something that runs anywhere from 15 minutes to longer that involves the class' content, not one of those 'get to know you' games...my kids know each other already. Ideas?
