This 2-day activity includes almost everything you need to know in an entertaining, visual format. Designed for 8th graders, but advanced enough for high schoolers, both the content and experiment will keep your students engaged. I included a link to a live version of the experiment I did in class, which will help you greatly in doing it on your own. While the material included is relatively simple, it's one of my favorite lessons of the year! Your students will laugh and learn a lot very quickly about Classical Conditioning!
