The AP biology students completed the data gathering for Activity B in the Osmosis and Diffusion Lab. We took 4 containers of water and placed therein a dialysis bag containing a different concentration of sucrose solution. We measured the mass of each bag before and after submersion in the freshwater. We will analyze this data on Monday.
The Chemistry students continued work on the Measurement Lab. We also introduced the concepts of mass and volume and how to measure volume of an object mathematically, if possible. We also looked at what pressure can do to an aluminum can, if applied correctly.
