Unit exam and rockin party

The unit exam was a fairly easy one compared to others. The large amount of study sources helped with that. Along with the fact that this unit itself was an easier one. Many of us did quite well on the quiz and i hope this transferred into the test. There were only a couple of questions that stumped me completely.

Today was Mrs. Frankenbergs birthday (pretty sure she's turning 27). We had a rockin party that comprised of ha on doing scholar bowl while everyone looks at him dumbfounded. It was a good relax day for us to recharge on brain snacks. Hopefully this next unit won't be hard. 

This week (so far)

Starting off with a Couple more lessons this week was the follow up to the quiz on Friday. Letting everyone fill up on them brain snacks. Two lessons happened which we will need to memorize for the unit test. Also we have had to do two different periodic tables (fake). To study for this test i will be going through all of the online quiz's, and doing the large packet with all the questions. The second periodic table made no sense to me at all. Some better explaining could have been useful there.

Weekly quiz.

This quiz was (as frankenberg said) not too hard. Most of the information was common knowledge by time for the quiz. Some of the simple rules are the ones i forgot (Hunds, Pauli exclusion, etc..). Some big tings that were Incorporated were the wavelength formulas and the different forms of them. I cant do a lamda symbol so just pretend its there. C=_F, E=hF, E=h(c/_). Overall the test could have been a lot worse. Going over the online quiz's helped me study and the note supplements from class are amazing.(keep using those).

spectroscopic analysis lab

Today we did a lab that used spectroscopes to tell us the affect in transmittance that two different elements had at certain wavelengths. The elements were cobalt and copper. While we were testing the transmittance we also tested for absorbency. The spectroscopes( not telescopes ) were machines which you put a vial of water in and set the wavelength at its proper setting and had the transmittance for water at 100. Then you change the water vial out for the cobalt or copper vial and check for transmittance and absorbency. Making sure the vial has no fingerprints or else the data will be bad.

Flame test lab

Today we explored the realm of FIRE (very little songs about ice though). We Took samples of certain liquids on popsicle sticks and put them over an open flame. Many of these samples turned into a variety of colors varying from orange to green and even purple. The part that was the most confusing was the blue cobalt glass. The flames where we had to look through the glass to see them were not showing much change.

New unit info

According to Mrs. Frank this will be a quite easy unit. "Easy" is a relative term so we will see how that turns out. Very quickly we have gotten into a couple sets of notes. All of the notes so far relate to waves. Luckily i took physics last year and some of this is relate-able. The idea of a wave is a set amount of energy is put outwards through a medium. Traveling infinitely in a perfect system. The most common wave we experience is the light wave. Other waves we encounter are radio and microwaves, and ultraviolet rays give us a tan. Most of the information we have learned thus far is pretty straight forward.
