1. Tomorrow will be a lab day, so please dress for it. We will discuss your homework (on molecular formulas) as well, and we may possibly introduce chapter 12 at the very end of class.
2. Tuesday will be quiz day for chapter 11. This will cover mole conversions (single and double step), molar mass, % composition, and empirical and molecular formulas. Need some practice? Try this review sheet! I will release the key over the weekend. We will start chapter 12 after the quiz.
3. Regarding your research projects: Please remember to refine your experimental designs and begin gathering materials and taking data. Again, keep in mind that you should be aiming for around 10 different trial types (iterations of your independent variable) and at least 5-10 trials of each. If a trial does not produce viable data, do not count it as a trial; refine your technique and try again (and remember to record everything!).
4. Your research project lab notebook should be separate from your in-class lab notebook. It should contain the same introductory information as a normal lab (table of contents, header, objective, materials, procedure, etc., to be updated/edited as necessary), but most of it will be data. Date every page. If you would like reassurance that lab notebooks do not need to be works of art, check out the lab notebook kept by Robert Millikan for his famous oil drop experiment. The important thing is that EVERYTHING is in the lab notebook, and that it is relatively legible and organized; nobody cares if it's a little messy or has a lot of cross-outs.
