RE:
Labs with beads

I
think this looks great.
Hey--I'll bring in the large red beads for the oxygen. Do you
want to use string, or do you want to use the fine wire I used.
I'll bring them in tomorrow, and we can compare.
Perhaps, we may want to mention/ remind/ draw their attention to
(question?) another point about the atoms of different elements--they
are different in size and mass.... the larger red bead versus the
smaller bead of whatever will bring that point home hopefully.
Thoughts?
I agree that we probably don't have much time to really devote to
periodic trends, but I do think that the different sizes of atoms can
be slipped in here (with or without minimal explanation in terms of
shells... which they've seen before in bio and middle school, size
increases going down, decreases going across the same row, or shell)
Thanks for making this up--YOU ROCK!

next
professional development

Hi
John and all,
Alicia and I already have stuff prepared that we would like to tackle
at the next professional development--basically we want to work on
creating a class set (or two) of manipulatives (dice, unit conversion
cards) that would allow students to learn the technique of dimensional
analysis and do unit conversions problems for mass, length, etc.
If it's okay, we'd like to spend the next department meeting working on
those as it will be labor intensive and with all the other stuff we've
got on our plates, I don't think it will get done unless we set aside
time for it. Other people are welcome to help, pilfer ideas,
whatever.
-Grace

development october 13th
We will use the afternoon of the upcoming professional day to evaluate
our current grade 6-12 science curriculum as a department. If anyone
has an idea or suggestion for other topics you would like to address,
please let me know. We have the opportunity to use this time in manner
we feel is most important and productive.

As a result
of sharing ideas with fellow cohort members (Mark Hayden's do nows,
Elinor Graf's alien periodic table, and more), I
realized that I could and should take a more active role in sharing the
good pedagogical resources I encountered and using collaborative
discussions as a way to improve old resources.
This first piece of evidence shows how I shared resources and worked
together with others in my department, specifically the other chemistry
teacher, Alicia Villareale. After recognizing the importance of
helping students "see" the submicroscopic aspect of chemistry (through
readings for my Edu536 course), I found a matter classification
activity involving beads and shared it with Alicia, in addition to
using it in my own classroom. We discussed other possible uses
for the
bead manipulatives, and she in turn developed a mass conservation lab
and chemical versus physical change lab using the manipulatives. We have continued to
work together and have increased our sharing of resources and ideas.
