CHEMISTRY: Great job with Part 1 of the Spectroscopy Lab using the diffraction grating! Here’s the mini-lecture on the intro to the hydrogen emission spectrum and the lab from Thursday. How are your drawings coming? If you have a question about the lab presentation, this is the vodcast with the instructions. Also, if you’re not going to be in class tomorrow, you can come by any time to make it up. The whole packet, including drawings, is due Tuesday.
