I apologize for not updated more last week. Wednesday and Thursday we finished did a lab looking at the cohesive (COHESIVE: Property of a liquid that causes it to stick to itself) properties of water, alcohol and vegetable oil. The lab was a basic one, involving adding small drops to a penny and counting the number of drops it took until the liquid spilled over the side of the penny.
It's fairly basic lab that asked you to initially make a hypothesis about what liquid you thought would be most cohesive. You should have found that water, with it's strong polar molecules, was the most cohesive. There were a lot of sources for error in this lab if you weren't careful. So, next time make sure you're very clean and careful with what we're doing.
On Monday/Tuesday, we started our introduction into BioMolecules. Download notes here: Biomolecules Power Point.
You can get a note sheet that goes along with the notes here: BioMolecule Notesheet
USE THESE documents to make sure you're successful on the test.
Tomorrow, we're going into the lab to explore Starches a little bit more indepth, so make sure you're wearing the proper lab attire.
