In AP Biology, we continued to work on lab reports. Rough drafts are due Monday, October 13th. The introduction section for your semester-long project is due on Friday, October 10th.

In Physical science, we did a lab concerning chromatography. Chromatography is the separation of pigments depending on their ability to dissolve in a given solvent. In this case, we were looking at the effect of alcohol, acetone or water on different types of markers. Some cool pictures from our results are shown below.
