Girl With BalloonsMy name is Joy Walker and I teach at Truman College in Chicago. I've been teaching chemistry since 1978 when I began as a laboratory teaching assistant for General Chemistry taught at Kansas University located in the lovely town of Lawrence, Kansas. I remember how much fun I had in laboratory making potions and exploring the variety of chemical changes I could produce. This is a subject that will always be relevant and promises no less than to reveal the secrets of anything that matters, well that is to say anything that is matter.

I believe that chemistry should be experienced through the senses and in this way we can recognize that we are not just surrounded by chemicals and chemical change but we are chemicals. As we learn about the secrets of matter and examine its behavior at the atomic layer a new revelation occurs. There are still mysteries waiting to be discovered.
