The Mole

This unit began with the highly anticipated mole. I did not expect this lesson to involve this much math and so many conversions. Initially, the whole process seemed like the hardest thing in the world. The Mole Road Map was a huge help in simplifying the process and making it much easier to remember the equation. After doing a few practice problems and memorizing the Mole Road Map, I really got the hang of it. I was now more confident when faced with these mole questions.

Last Meal Party Day

Boy oh boy was it spectacular getting to feast on food two Friday's in a row. All of my friends were filled with jealousy. They were asking me "What kind of class is this that you have a party every Friday!?". Then when I told them Chemistry they questioned why I was having so many parties in Chemistry class and I just smiled. I made brownies as my treat, and my classmates seemed to enjoy them. I was very intrigued by the puppy chow! Two people brought it and I had about 4 bowls of delicious puppy chow. I then walked around selling my brownies to my friends and some teachers which was really fun as well. It was so great to have a day like that following a test. Hopefully, we can have more days like that in the future!

Matter and Measurement Unit Test

Coming into the test I did not have the most confidence. This is mainly due to the poor result I received on the quiz earlier in the week. This unit test had more of the newer stuff we learned compared to the significant number questions on the quiz. I don't know how or why, but it felt as if everything was clicking for me on that test. I'd have to say it is probably the best I've felt on a test or quiz in here all year. I'm awaiting the (hopefully good) results.

Mole Day: Project and Party

My initial thought of this entire subject was "What? Are you serious?". I was wondering why on Earth we were SEWING a mole for chemistry class. My parents were also baffled at the idea. In all, it was pretty fun. I had a fairly good idea being my MoleZOU (A Mizzou Mole) except that I am not the best seamstress, and that resulted in a not so great looking mole. Everyone said it looked much more like a fish than a mole. I spent a lot of time on it for people to criticize my fish/mole. :( Their were some fantastic and creative moles that I saw on Mole Day, and the party was awesome. My friends and I talked about Fantasy Football and ate a whole lot of yummy treats. It was a delightful Mole Day.

Pre Test Thoughts After The Lesson

This time I wanted to combine some of the confusions and unknown information from the pre-test with the new things I learned from the lesson. The biggest topic that came up throughout the test was significant numbers. I was thinking that I could have a pretty good guess at what they were, but once I got to learning what they actually were in the lesson, I found out I was way off. There are many rules to these significant figures making it hard enough, but then you have got to deal with addition and subtraction. That adds a whole new level of confusion to this lesson. Overall, I think I am getting the hang of it pretty well, and I feel pretty good about the quiz on Monday.

Archeology/Half-life Lab

For this lab there was no question. That guaranteed me getting to participate in this one. That being said, we ran out of class time so my partner had to take it home and collect the data. It turns out that I didn't really get to do another lab. Which might've been a good thing since this lab seemed very strenuous. We had to cut out over 500 squares and then my partner had to take those small squares home and imitate a decaying process. He had to dump all of the squares out and count how many landed on the color side. The other ones were decayed in a sense. The lab was a great way to think about half-lives and the decaying process differently. Hopefully the next lab will be more fun.

Beanium Lab

Well this wasn't the best start to the pre-lab questions. I was one of the few who answered incorrectly and ha d to sit out on the lab. I had simply forgotten the formula to calculate the average atomic mass and I had to guess. I guessed wrong and had to pay the punishment of sitting out of the lab. I didn't get the privilege of actually doing the lab, so I had to use data that Mrs. Frankenberg gave us. I am going to make sure I get the question right next time.
