He was the best chemistry teacher I've ever had. It's always been my worst subject and I've basically hated it in the other chem classes I've taken, but he made it so much more understandable. He's a great teacher. In my opinion, you want him for chemistry no matter what if you can get him.

Great Professor. Relatively entertaining lectures that taught the material well. As long as you paid attention in class (there are easy clicker pts) and did the online homework you could get a decent grade. There are also plenty of resources to study from such as SI and the book problems listed. I did neither, which is probably why I got a B.

I can say with confidence that Greenbowe was by far the best professor I've ever had at Iowa State. He keeps his lectures entertaining yet still relevant to everything that we need to know. He makes topics easy to remember by relating them to real life situations, & puts all of his lectures on BlackBoard which is great for reviewing before exams.

As a person who has taken honors chem in high school, and has little to no interest in chemistry this was probably the most difficult class to take. Be prepared to learn a bit on your own. The professor goes through the lectures fast and glosses over important stuff. Keep a tab with the slide notes open so you can keep up. Nice professor,hard class
