Chemistry teachers will tell you that there is an experience they have all had many times. Someone will ask them, "What do you do for a living?" and when they reply, "I'm a chemistry teacher," the all-too-common response is: "That was my worst subject!" Why is that? Is high school chemistry just so intrinsically difficult that only students with great intellectual gifts are capable of succeeding without heroic efforts? The Easiest Class in School Professor Frank Cardulla doesn't believe that for a moment, and he will hopefully convince you, as he has thousands of high school students, that "chemistry is the easiest class in school."
