Chemistry Labs (INS 2006/07)
spring quarter labs will be from 8.30-11.30 a.m. and 12-3 p.m.
Lab assignments will be posted here. It is your responsibility to print your lab write-up and complete the pre-lab assignment before attending the lab. You will not be admitted to the lab unless this is done.
