This model-making lab can be done with the model kits or with paper-made atoms. I use this lab after I have lectured on macromolecules in Biology, but it could be used for organic Chemistry too. Students bring their models up to me for a stamp, but you can walk around and stamp them that way also. After students make these molecules they really understand their structure much better. You will have to make sure they have access to pictures of the molecular structures either from a textbook, lecture notes or internet.
