As Mr. Baker collected the assignments near the end of the class, Janelle raised her hand to ask a question.

“Mr. B., this lesson was interesting and all, but it seems like we’re getting more into biology. When do we get into the psychology stuff?”

Mr. Baker nodded. “It’s true, we do focus a bit more on biology at first, Janelle. And it’s possible that you’ve already learned about some of the parts of the body we studied today in biology, or even family life. But you have to remember, every psychological experience we have can only occur within the confines of our physical bodies. Just about every bodily experience we have has a psychological component, and psychological events are simultaneously biological ones.”

“Yeah, I get how that makes sense with the things we were talking about,” Marcos said. “Like when something jumps out and scares you it gets your adrenaline going. But what about when you’re just, like, sad about something? You know, when something’s like, all in your head?”

“But,” Cindy stepped in tentatively. “Even if something is just in your head, isn’t it still in your brain? And that’s part of your body, right? I mean—it has to be happening somewhere.”

Mr. Baker smiled as the bell rang. “I don’t think I could have said it any better myself, Cindy. The biology of the brain, where all of the things that are "just in our head" happen, is exactly what we’re going to look at next.”
