CHEMISTRY: One man’s rust is another student’s lesson in chemistry! From Wednesday – here’s the lecture on oxidation numbers. Now go out and apply them! Need help? Don’t forget the practice at sciencegeek.net. Go to sciencegeek.net. Also – help session tomorrow morning at 7:15ish A.M.
UPDATE: Homework change – do the book work, make corrections to Chemical Formulas worksheet 1, and bring Worksheet 2 to class but don’t do it yet.
How have you been doing on the polyatomic ion quizzes? What about the pre-test MONDAY? For the pre-test you need to have memorized (and be able to use!!): polyatomic ions, monatomic ions (but you can get these off the periodic table), acids, prefixes, the chemical names and formulas of common substances, and the oxidation rules.
That’s a lot, but you can do it! And make double dog sure you are working hard at memorizing it all now!!

Watching the lesson on the screen without you teaching us in person was different, yet I felt like I learned the same information the same way.
I agree with Morgan – but I did miss the student interaction with the teacher!
im glad im doing well on the quizzes
The whole idea behind oxidation numbers seems really easy. I hope it really is once we start using them.
Had fun learning about oxidation numbers this week!
I enjoyed the chalk activity today. I never thought that my name could be measured!
Thanks for the help sessions! Is our text on Monday or Tuesday? 🙂
Rachel – Pre-test is Monday!
I think I finally made a break through today
Practicing writing formulas in class yesterday helped tremendously. I feel like I understand it much better.
Do we really have another help session tomorrow morning?
John – Yes! And I was glad to see that you were able to come! 🙂
Working on the chemical formulas worksheet in class today really helped me.
Im glad we worked on the chemical formula worksheet in class it helped. I think i am getting this a little more each day.
On our syllabus it says the test is Monday but on this post it says Tuesday. Which day will it be?
Lindsay – Sorry – typo! The pre-test is Monday!!
Does our science in the news need to have chemical compounds or chemical formulas in it? Can this include a molecule?
Sidney – Either one is okay!
I’m understanding the chemical formulas much better now!
i am understanding how to write chemical formulas way better now! Thanks for all of the help!
Getting worksheet 1 checked in class and being able to correct the ones we missed was very helpful!
Thank you for letting us correct out formula worksheet.
Once you understand chemical formulas it is easy to write them.
Thank you for showing me what I missed on the chemical formula worksheet so I could fix it.
Thank you for helping me understand chemical formulas better it helped a lot on worksheet 2.
I was finally able to understand the formulas on Worksheet 2! Thank you for helping me catch a few mistakes(:
I enjoyed working on worksheet 2. It really is starting to make since.
I really like all the practice we have been getting on ionic compounds.
Are there any cases where the oxidation number is different from the charge?
Thank you for letting us have another help session the other day. It really helped a lot!!
After the help session the other day, I was able to write a chemical formula better.
I am glad that I have been able to write chemical formulas better!! Working on the sheet in class Thursday really helped!
thanks for the extra formula practice. this will help a lot for the test mon
The sheets on chemical formulas helped me understand how to write them more.
I am finally starting to understand the material did some much needed studying tonight!
Thank you for your help on chemical formulas. It has helped me out a lot!
Thank you so much for the extra practice with chemical formulas! it helped me out a lot!
