In the past, I have shied away from the physiology that goes along with psychology because in many cases I did not know what I was talking about or I did not know an interesting and helpful way to teach it. When I started teaching AP Psychology I could no longer side step it, I had to at least "cover it" in class. My methods were not always the most sound, but I have come a long way. Here are some tools that I use when teaching about these very important concepts.

This final video is an Animaniacs clip of the Brain Song.
Several of my students told me that songs like these really help them remember.
