This last unit was a build up on the unit before. It was pretty much about balancing equations of reactions. It requires you to know charges of atoms and ions. It was pretty much a math filled unit. It is about chemical reactions and how atoms are never lost. They are just converted, so both sides of the reaction should equal out. This unit involves all of the other units in that we use ions and charges similar to unit 6, we use chemical formulas similar to unit 5, but all of the other units were pretty much review. 

This trimester was pretty fun. I think I was strong in all of the units except for the unit that the first test was on. I got an A- on the test, which was pretty disappointing, but I have learned the test material that I missed. I feel like I had very few weaknesses and many strengths. One of my weaknesses was labs this trimester. It was very hard to understand the connection between most labs and the material we were learning. One of my strengths was how fast I was able to absorb the material. 

My grade is pretty good, but what I would have done to improve it is to have aced the first test. I could have studied a little harder and I could have gotten a much better grade on that test. 

I feel like we could have gotten a lot more done without the white-boarding. That took up about half of all our class time. We could have spent that time more effectively and maybe made this class a one trimester course, or we could have engaged in more labs and learned more about them. I liked the review days a lot because it clarifies everything. 

I don't really think blogging was helpful. It just served as a summary for the week but it didn't really need to be thorough. I think we should get rid of the whole blogging idea except for an end of the trimester paper. Those are my recommendations. Overall, it was a pretty nice trimester.

This week in Sg Chemistry 2, we took a test on unit 6 and we also started a lab. This lab, which involved nails in copper chloride, was to show how chemical reactions appear and how we know when they take place. Things such as temperature change, phase change, and color change can show us if a chemical reaction has occurred. We haven't completed the lab yet but we discussed some predictions about what could happen. Mainly, this week was pretty much a time to prepare for the test, and taking the test. Our lab only occurred on the last day of the week.

The test was pretty challenging. It was definitely the most challenging test we have had in this class. I hope I did well but I can never truly predict any of my test scores. The test consists of naming ionic, molecular, and polyionic compounds. It also consisted of examples from the first lab we did. It was the sticky tape lab and it showed diagrams of electrons. Unfortunately, I do not have pictures of the test or its examples. It also consisted of multiple choice about JJ Thompson and his cathode ray experiments. We also had to find how many ions are in a compound and how many atoms are in a compound. That pretty much summed up the test and the week. 

The next thing that happened in class was a lab we did on friday. It was a three day lab and we submereged nails in a copper chloride solution. We will further examine what changes happened on monday. We discussed what might happen before we started the lab. We said that there could be temperature changes, color changes, and even phase changes. Unfortunately there are no pictures of the reaction and its result but that will be included in next weeks blog. 

In conclusion, this week wasn't as informational as other weeks. It was just a test and one lab. Hopefully I did well on the assessment.
