Well, I'm glad I got home safely. Got a friend's bday tonight so I'll get to enjoy the night and relax (or party hard) a bit. My biology test today was rather easy. A classmate told me that he makes it easy so it'll keep students from dropping. Something about being able to drop the class should the first midterm performance be poor. Odd but interesting concept.
My bio lab class afterwards was interesting. This was going to be a long lab but the teacher split the class into four big teams to cut down the time. I joined the electrophoresis group since I've never done that stuff before. Easy but fun stuff with preparing and watching things move towards the poles. The other groups were doing column and paper chromatography. The groups that did the paper chromatography messed up. Instead of using pencil to mark the level they used markers. lol. So it ended up with the marker oils being sporadic and all over the place. LOLOL.
Since I'm talking so much about school I have another story from this week. Gen chem II lab was frustrating. Easy lab but frustrating partner. Tweek is his name, as you may know. We're doing simple acid v. base titrations. When I read the procedure it mentioned about the accuracy of the volumetric burets to be to the 0.10 ml. I mentioned that to Tweek and he refutes that because the hundredths digit would be uncertain. I murmur "that's the point".... moron.
On to what did frustrate me. I did the first titration to show him how to work it. Our indicator was phenylphaline, which goes to pink as a indicator (just reminding). We did three initial trials and the measured volumes of NaOH used came out to be: 5.2 ml, 4.7 ml, 4.9 ml. He got worried because the first trial took more amounts to titrate than the rest while actually being a lighter pink than trial 2 and 3. One of the possible reasons that I gave was that we used top loading balances that could easily be affected by air current. He just wouldn't accept the first trial.
So I just did another trial to shut his blah blah mouth. When weighing the solid, I demonstrated the errors that come from top loading balances and blew my breath onto the balance and showed him that the balance can give off a wrong reading. Then after titrating that fourth sample, the volume titrated came to be 4.3 ml. Tweek says let's keep that one and throw out the first trial. (Anyone see something funny here? ) I told him that we should keep all trials. We began arguing, and it ended up being stupid and pointless so I just let him be. He even ERASED all his first trial data. Sigh*. Of course, the average of the trials with calculation of the sig figs ended up both of us having the same results.
Upon cleaning up there was some NaOH left in the buret. He took it while I took the E. flasks. He was about to dump the NaOH into the original NaOH container. Of course, Super Beeho steps in and tells him not to for ethical reasons. He decides to still do it since he just saw someone else do it while I was ordering his dumb ass not to. What's worse is that the teacher told others to do the same. LOLWTFBBQ. I don't like Tweek. Of the four labs classes I have, this is the worst.
However, I really like my elem gen chem lab class. My partner is a cool guy named Jeremy. He's open minded and really wants to learn how to do things right in the lab; asks me lots of valid questions and we enjoy and learn from the mistakes we make. And he's very opposite of Tweek so not all is bad at SLCC.
That was a long read, I know. But you're just bored at work, aren't you? So I don't have any guilt from typing this. I hungry. BYE.

4 lab classes? Damn...
I have just 1 (well 2, if you count the anatomy part of the anatomy class)... and I hate it. Having 4 sounds insane.
i miss lab :(
