Biodiesel Project

Our biodiesel project was outstanding in my opinion. We made a cartoon video that had a different characteristic for every letter in biodiesel. For example, B stood for biodegradable. Our video was short, sweet and to the point. Hopefully we will get more people to use biodiesel and get some moolah.

Lecture Supplements

The chemical bonding was somewhat difficult. So many tips and tricks to find the chemical makeup and the small little exceptions to every rule that we have to know. So that is a little tricky to determine when to use each rule and when the exceptions apply.

New Unit

Starting off a new unit, and putting the entire third quarter behind me. I began the third quarter with an incredibly rough start. It's so bad that we don't need to discuss it. I ended strong though with an 80% on my last test! Which is incredible for my standards. 

This unit's first lecture was about Lewis' structure and how to draw electron dot diagrams and show bonds and lone pairs. We also learned the Have, Need, Share method to draw and figure out electrons.

Unit Test

I wanted to do a post about the exam of this unit, but the results weren't very "good". My test score was close to the freezing temperature of water in Fahrenheit. I think that's enough said. I'm going to go cry in a corner and do better on the next test.

Vitamin C Lab

This lab was a blast. It was very cool to be dealing with household liquids rather than a bunch of chemicals that I don't know. We had to take a variety of liquids like:apple juice, V8 juice, pear juice, and grapefruit juice along with starch and determine which one had the highest and lowest vitamin C concentration. It was one of the more enjoyable labs, hopefully we will have more like this one.

Locating Electrons and Electron Configuration

I am loving this unit so far. The less math and calculations, the better. In this lesson we learned about how to locate electrons and I understood it with ease. First you would locate the principle energy level, which is basically which row it was in going across the periodic table. Then you would find the sub-level it is in. There are four sub-levels: S,P,D, and F. After that, you simply counted the number of elements into that sub-level to locate your beloved electron. All of these components were used to make an electron configuration. For example: Oxygen has an electron configuration of 1s^2 2s^2 2p^4. The lesson was enjoyable and easy, what a blessing.

Wavelengths and Energy Calculations

This lesson had something very rare. It contained some information that I had prior knowledge about. I cannot remember a lesson where I could recall knowing something that I had previously learned before. This information was the basics of wavelengths. The good ole spectrum that listed the wavelengths in order of smallest wavelength / most energy to the least energy / longest wavelengths. It was quite refreshing to see something familiar, but with that came many new things. Calculating energy and wavelength with frequency didn't seem to difficult, but all of the equations got confusing and could sometimes be hard. In conclusion, this is still my favorite unit, and it is still fairly simple.
