Stoichiometry Week 2 Post #3

Today was test day, and I actually felt pretty good about it. I walked into class feeling pretty prepared  because I did a lot of practice last night with the practice tests and I studied the weekly quiz. Overall I've felt pretty good about this entire unit because I've understood it from the get go, which made it easier when we built on it with more complex concepts. I hope I did as well as I think I did, but I'll just have to wait and see.

So last week's quiz went okay, I was feeling really good about it when I walked into class but during the quiz I kept getting answers that were just slightly off from the multiple choice answers, which was frustrating. After the quiz I was unsure what my score would be, but it ended up better than I thought it would be, which was good. Last week I went over the quiz to see which questions I got wrong and why and it was really helpful, so I hope I don't make those same mistakes on tomorrows unit test.

Last week on Thursday, we started the Cu (II) Chloride Lab. From reading over the lab beforehand it seemed pretty simple, and both my lab partner and I made in into the lab pretty easily. The lab was really fun because we got to react a nail (Fe) with CuCl2 in a baby food jar, and then after the weekend we came back and got to see what exactly had happened. It was also interesting because Mrs. Frankenburg had told us that Iron would either react with a 2+ charge or a 3+ charge and it would be totally random which charge of iron our nail would react like.

I haven't had this feeling since, like, the first unit. This feeling of actually understanding the lesson. I was afraid this unit was going to be pretty difficult, but so far it's going well. I'm really happy and proud of myself for actually understanding this. I just hope my knowledge doesn't go straight out the window, when I take the quiz tomorrow. I'm hoping I can at least keep it together until then. These are some helpful links and videos I found:

Test Day. The two most dreaded words. I was extremely nervous for this test because I had done so poorly on the last one and I couldn't afford to fail another test. Going into this test I felt more confidant about my knowledge and understanding of the material and I'm hoping my score will reflect that. I will admit there were some questions that I didn't know how to answer but I gave it my best shot and moved on to the questions I did know how to do. I'm nervously awaiting the day when our tests are put in the grade book, wish me luck!

Yesterday we got to do the metals lab. It was actually pretty fun and easy, all we had to do was put 6 different metals in six different well plates and then add a solution to the well plates and watch for a reaction. Sometimes it took as long as 10 minutes for the reaction to take place, but not all the metals reacted each time. The only metal that reacted every time was Calcium. Then once we had seen all the reactions we created our own activity series based upon the reactions of the metals. Overall I liked this lab and it was fun to see what metals would react and which ones wouldn't.
