Chemistry 11:  Thanks Ms. Pynn for running today's class!  Lab 3A was handed in today.  We began with a Mini Review of Density, then we did Lab 2D, which taught us about paper chromatography as well as gave us good practice with significant figures.  At the end of class we did another Measurement and Sig Fig quiz, just like Friday last week.  For Tuesday, have Lab 2D finished (all questions, follow-up questions, no conclusion).  Also, you are encouraged to come with me on the Discover UBCO Field trip next Wednesday - sign up in the office and get a permission form.
