Good day all! I hope you found your weekend relaxing and/or enjoyable.
Today we came in a took our little test over BioMolecules. It was a 15 question scan-tron test covering our last unit. If you missed it, you need to make sure you make it up, otherwise you'll receive a score of 50%. If you need to download the notes, you can go to iportal.4j.lane.edu and log in and download it, or just look back a few posts here on the blog to download it.
After the test, we answered some questions about the history of Cells and such. Cells; that's going to be our next unit of study. Bill Nye the Science Guy introduced us to them today with an enjoyable episode.
Tomorrow, we're going into the lab to learn how to work with the microscopes including learning how to properly set up a wet-mount slide, focus the microscope and the process of taking detailed drawings of what we're observing.
It's a big lab activity and it should take us through until the break.
Cheers,

Well, were almost done until Winter Break. One week to go.
To was a crazy Friday with the short periods, so we weren't able to get much done, but I think we got enough.
We started with our Brainteaser warmup, handed back your Starch Labs from the other day and then jumped right into finishing our notes.
Today our notes took us over Proteins, really hitting on how wide a variety there are and how important they are for every, day-to-day cell function through Nucleic Acids, the masters and lords of the cell processes.
DNA and RNA are both really cool molecules and we'll be looking at them a lot closer during our Cell unit, which is the next unit up.
Monday/Tuesday we're going to have a test of this MacroMolecule stuff, so be ready by opening your notes over the weekend and re-reading what you wrote.
Have a great weekend,

Wednesday/Thursday, December 8th/9th.
Today we started off by watching THIS video about the dangers of making a panda angry. We then refreshed our memories about what a starch is (long polysaccharides, or long chain of sugar molecules) and then went into the lab to test for starches using iodine. There were about 13 materials for you test and look for a chemical change in the color of the added iodine. The lab was due today. If you didn't finish it, or need to do it, see me after class.
We then came back into the class room and took a few notes about Proteins, the all-stars of BioMolecules. Proteins do a lot of different tasks and there's a nearly endless number of them in all sorts of different configurations, sizes and shapes.
Friday, with our shorter periods, we'll be looking to wrap up our notes with Proteins and looking at Nucleic acids. Then, it's on to cells.
Maybe we'll test first though.

Monday/Tuesday, December 6th and 7th, 2010.
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.
