This is my new blog. I have started this because I wanted a place to share information I receive from colleagues with students, information from students with other students, information from students with colleagues, and (break into the “Circle of Life” song from Lion King to get the full effect) learn more myself!

Cool blog!
Thanks for your help in getting this started. I hope I can make you proud!
I realy like how you want to help kids! Its a great thing you are doing.
-rock on-
Thanks, Amanda. I hope that we can make this really useful. We’ll see how it goes. Thanks for checking it out!
This is really cool. I will have to add this to my favorites…..
Just in case I ever need help…..
Glad you liked it and thanks for visiting! Let me know if there is anything you would like to see here that would be helpful to you in the future (like if you find any good chemistry sites while surfing the web). Have a great weekend!
I’ve said it once, twice, 3’s a charm (something like that) but you really have a gift at helping us understanding things even for us “visual” people. Keep up the great work Mrs. B ! I’ve been looking for some Chemistry sites, and I’ve found 1. It’s really awesome. Search “Virtual Chemistry.” You can make compounds, weight stuff, measure stuff, and all that jazz. Well, see ya later.
HH PLEASE!!:) (Applied Chem) (per.7)
Ok, in the book on page 129. Problem # 3
“Mark the zeros that are significant figures in the following numbers.”
letter C. 1000 (no decimal)
I’m know not sure what zero is significant or not significant because there is not a decimal. Are those zeros considered “place holding” zeros? I can already tell this chapter might be a doozy. I’m willing to do another worksheet and have you check it for NO credit. Just extra practice kind of thing. ( Doesn’t help grade or lower it) and other question was I’m not understanding “writing out the number and circling zeros.” I remembered it in class, but now I can’t. I know you explained it once, but if you could explain it again that would be so awesome!
Thanks much,
Carrie A.
Carrie,
You are correct that the zeros in 1000 are placeholders. If you cover them up, the one would be in the ones place instead of the thousands place. Therefore, these zeros are not significant. For number 3, just write out the number that they give you in the book. Then, circle or put a box around the zeros in the number that ARE significant. IF they are not significant, leave them alone. Then, in #4, use the same numbers from question 3 and count how many total numbers were significant, zeros and nonzeros. I hope this helps.
Check back at the top of the A. Chem page because I posted some links for Significant Digit help. Try those and let me know if you need more help tomorrow.
This is a really cool website!!! i like it!!
