I use this short PowerPoint on the first day of psychology class to introduce what psychology is by relating psychologists to reality television viewers. Psychologists "watch what happens!" just like Bravo's slogan.
You could start off the lesson with a little 4 corners activity. Ask students which reality TV show or social media outlet they prefer. Give them four choices, designated 1,2,3 and 4. Students answer by going to the corner that corresponds with their answer. I do this a few rounds before I start the mini lesson.
