Chemistry 4-25-18 Describing Chemical Reactions

CHEMISTRY: So tell me again – how do you know if a chemical reaction has occurred? Here’s the lecture on the evidences of a chemical change and the intro to balancing chemical equations. Great to be back to chemistry!

  1. This week I rate myslef a 4/5. I retook the test today and I feel very good about it. I am so glad that the project is over. I went to the help session and it helped me a lot. I have learned that I need to not wait till the last minute on stuff.

  2. This week I rate myself a 4/5. I did not do well on the first test so I retook it today and feel much better about it. I feel like I prepare myself better for the retest. I am very glad that the project is over and I feel like I did well on it. The project thought me how to manage my time wisely because I had to stay up on Sunday night and Monday night to make sure I had it done.

  3. This week I would rate myself a 4/5 because I think I did good on my project. I also did good on the test so I didn’t have to retake it.

  4. This week we got the test back. I did not do nearly as good as I thought but I still didn’t do too bad. I decided not to retake the test because my grade can be pulled up pretty easily and I didn’t want to risk doing worse. We also finished the project which I worked really really hard on and I feel really confident about. I would rate myself a 3.5/5 this week.

  5. This week I would rate myself a 4/5. I felt like i could have done better on the test. Also I am glad the project is done.

  6. This week in chemistry I kind of struggled on the project but I came back strong and I think I did very well on the retest

  7. This week I would rate myself a 4/5. I think I did fairly well on the project and did really well on the retest.

  8. This week was an okay one for me. My triumph was getting the project done. My struggle was not doing good on the test but I feel like I did better on the re-test. Overall, I would give myself a 3/5.

  9. This week I was very excited that I finished the project. i feel like I did really good on it because i spent a lot of time researching and put a lot of time into it in general. Also, I was very glad we got to take the test again!!! i really prepared for it. I was kind of confused on a few of the multiple choice but I think I did better than the last test.

  10. This week, I would rate myself a 3/5, because I understood most of the things we went over in the notes, but I had trouble with the problems in our homework that involved making the right side of a chemical reaction, such as knowing which atoms are together and which atoms aren’t. Also, I still have slight trouble with some problems in balancing chemical equations.

  11. This week I rate myself a 4/5. I felt that I did well keeping up with work I just have a busy schedule so I have to work around it
