Two students in the second semester of general chemistry meet with their teaching assistant in a 7th floor write-up room. Every lab has a connected room to work up data and talk to labmates without wearing protective equipment. The walls and windows are all writing surfaces.![Several people lined up working at a lab bench](https://news.wisc.edu/content/uploads/2022/04/07Chemistry_Building22_5828-1024x681.jpg)
