207 Chemistry Laboratory Welcome to the Detroit Local Section ACS Laboratory Hello, I am Dr. Zhi. No, I am not a medical doctor, I just went to college for a very long time so I can teach chemistry. That is what I am doing here today. I have volunteered to help a group called “Kids and Chemistry” teach some kids. But I think they are playing a game of hide-and seek on me. They are in the laboratory, can you help me find them. Just click on an item in the laboratory and if they are behind it, they will come out. Click on the door to begin the game. Organic Chemistry
