  1. This week was kind of a stressful week with the project and all but I got it done on Sunday so I didn’t have to worry as much Monday night I have struggled a little with chemical equations so I would rate myself a 3/5

  2. I rate myself a 4/5 for this week. I am soooolo glad that I have turned in my chemistry project! what a relief to have it done! I think i’m getting the hang of balancing equations but I need more practice before the test!

  3. this week was ok. im really glad i got the project over with but now im in chicago and that really stresses me out because i know im missing class. looking forward to a good week in chemistry!

  4. This week in chemistry I rate myself a 4/5 I felt like I understood the material and I turned in my project which felt good.

  5. this week of chemistry was great. I really enjoy doing the chemistry project and hope I did very well. I love doing the chemical equations and how to do them.
    I would rate this week 4/5.

  6. i felt like this week was okay for me. the project stressed me out but i’m relieved it’s over and done with. i’m kind of iffy on how to balance chemical equations

  7. This week in chemistry I finally completed the chemistry project and I am so relieved. I have understand balancing chemical equations pretty well and I did good on the cLab. I am excited to finish off this year!

  8. This week I would rate myself a 3/5 because I was very stressed about the project. Also I am very tired because I have barely slept this week too. Another thing is that I am not understanding balancing equations very well yet.

  9. For our homework, part C to be exact, what does it mean by the type of equation? I think I might have found something that matches what we are looking for in section 2 but I am not positive.

  10. This week I would rate myself a 3/5. I give myself a 3/5 because I finally turned the project in, which is good so now i am less stressed but we just started learning how to balance chemical equations and i thought i was doing okay, but turns out i definitely need to practice more and espcially before our next test. I also have a question about the homework on Part C of the C-Lab. What does it mean by type of equation? Thanks in advance and I’m looking forward to another great week in chemistry!

  11. This week was definitely a triumph. I turned in my project on Tuesday and i feel pretty confident about it. The project was a lot of work but i feel like i learned a lot through it. I also kept up with all of my homework but i am kind of confused on the equations.

  12. This week I would rate myself a 4/5, I say this because i believe I did well on my project and i am finally over the stress of it, and also that I previously knew how to balance chemical equations. I found the cLab pretty easy to do. The lab we did on monday was fun and it took me little time to figure out how to do it.

  13. This week in chemistry I would rate myself a 3/5. Turning in the project was very stressful, but I am glad it is over. I am ready to get to work with all the balancing the equation problems.

  14. This week I rate myself a 4/5. I’m really good at balancing chemical equations and I’m so relieved that I finally got my project done.

  15. This week I would rate myself a 4/5 because when we first got introduced to chemical equations i was completely lost, but after the homework practice i caught along. Also the stress of the project is over so this week was good.

  16. I would rate myself a 4/5 this week. I finally got that dreaded project complete and turned in. Phew, what a load off! I can only hope that I got at least a somewhat decent grade on it, I know it’s not my best work… On a brighter note, the material we learned was fairly easy stuff, and I feel pretty confident!

  17. I would give myself a 4/5 this week. I don’t have to stress about the project anymore and I completed and turned in all my homework this week. The video of zinc was cool to see.

  18. This week I rate myself a 4/5. I finished my project and have started to get the hang of balancing equations. I’m looking forward to the next test.

  19. This week I would rate myself a 4/5. I took good notes and understood how to balance the equations. I also got the project done in time.

  20. This week I rate myself a 4/5 I understood balancing equations pretty well. snd It was a huge relief to turn in my project

  21. this week i rate myself a 5/5 i have already learned how to do the balincing equations so thus week was review for me and i think i did good on the project.

  22. This week went very well! I completed the project and can finally relax! I remember doing chemical equations in IPC so it should not be that difficult. This week over all was so a success and I’m excited to finish the year

  23. I would rate myself 4/5 this week cause I’m so excited that this project is over with and I’m doing really well with balancing equations

  24. I would rate myself a 3/5 this week because I did pretty well on the lab and I was able to turn in my project on time.

  25. I would rate myself a 2/5 this week. I was very stressed with this project and I worked a lot on it, but the rest of the week I wasn’t very focused much at all which isn’t good. Hopefully next week I can get back on track.

  26. I would rate myself a 4/5 this week because i think I did good on the project and I watched the videos of the lessons I missed this week.

  27. This week in chemistry, l give myself a 3/5. l conquered THE PROJECT!!!!! l finished it at 4 am..but the best feeling was turning it in!!! Hopefully, my hard work will pay off. However, l did miss a lot of class this week…l need to catch up. l am kinda sad chemistry is almost over…but It’s okay cause l survived in the Don Juan Basin!!! (SOX 2018)!!!

  28. This week I give myself and pretty much everyone else a 5/5!!! I completed the project, and that is such a weight lifted off my shoulders. The project was so much work, but once I finished it I felt so proud of myself. Balancing chemical equations comes easy to me, so this week has been a success.

  29. This week was a 5/5 for me. I’m done. The project is finally over and now I can sleep all I want. I hope that the project brings me a good grade. The next chapter of chemistry isn’t bad so far, but I don’t know about being ready for a test by any means.

  30. I rate myself a 4/5, I was very stressed up until the project turn in date, after wards I felt like I did good on the lab and took good notes

  31. This week was quite busy. From the chemistry project taking most of our sleep on Sunday and Monday to trying to learn more new material. I’d rate myself a 4/5 for the week. I stayed on task except for one little homework slip at the end, but I’m fairly certain I did well on the project.

  32. I rate myself a 4/5 this week. That is because I think I did pretty good on the project and I understand the new material we have been learning. I also stayed on top of my homework.

  33. I would rate myself a 3/5 this week because the project was stressful and I am struggling a bit with balancing chemical equations.I am ready to finish this year of chemistry off strongly!

  34. I give myself 4/5 this week because I feel like I did well on the project and I feel like I understand the material we covered this week

  35. This has been a super stressful week! With the project being due I was really worried about it making sure I had everything together in the right spot. However with the project being done it has been a bit more calm!

  36. I would rate myself a 5/5 this week because I turned my project in whole. I feel like a boulder sized weight has been lifted off my shoulders.

  37. This week I give myself a 4/5. I stayed up later than I should have on Monday night finishing the project, but I’m actually enjoying the new lesson. Some of the equations can take a while to figure out, but overall they aren’t very hard. And I actually think they’re pretty fun.

  38. This week I rate myself a 4/5. The project was a nightmare and a half but now it’s over. All we have left to do is one final test then exams. I posted a question in my previous comment but I wanted to make sure it didn’t get lost. Now it’ss time to get a good night’s sleep.

  39. This week in chemistry I rate myself a 3/5. I got a good grade on my test, so that made me happy! However, I did awful on the first balancing equations worksheet…I think I just rushed through it since I did it late at night which was not smart! Even so, I feel better about the whole concept because we had the help session this morning. Also, I’m ready for the memorization quiz tomorrow and hoping to bump up my score from last time.

  40. This week I would rate myself a 2/5. I did not do well on my test and I should have studied more. I also need to work on balancing chemical equations since I did bad on the worksheet
