The Chemistry students continued working on the Measurement Lab. Most groups got to Part 2 of the lab which focuses on Mass and Volume. The students learned that we have electronic scales to measure mass, that beakers are not for measuring volume accurately and math can get you out of a jam.
The AP Biology completed the data analysis section of Activity B of the Osmosis and Diffusion Lab. We compiled class data, averaging the percent change in mass of the dialysis tubing that was immersed in different sucrose solutions of varying concentrations. Yup, that's what we did.
