Re: [Channel-talkchemistry] any watched some of the video segments?

I'm working by myself, and there have been times that I would have liked to
share ideas with another person or ask them questions. Like for example,
did you try to access the safety information for working with radioactive
substances described in video 3 (listed in the safety section of Ms. Berry's
activity on p. 111). I was concerned about the use of gamma radiation
sources in a high school lab and was curious about what the state of IL
standards said. However, I was not able to access that web site. Could
(any of) you?

Another question I'd like to throw out there: in the pre-workshop
preparation for workshop 3, it asked us to choose a topic about nuclear
chemistry that we find complex to teach. I always find binding energy
difficult to help the student conceptualize and I wondered if anyone had any
nice analogies/activities/demos that might help?

Also interesting thought, Kathleen, about having students tell us what they
want to "see"...what kind of answers do you think you will get? Should be
interesting!

Thanks in advance!

Kathy

Kathy,

I have watched the first three segments of the videos and completed almost
all of the homework for those three videos. So far I've found most
interesting video number three. I picked up some ideas that I'd like to
use in my chemistry classroom. On the first day of school I might ask the
students what they want to "see" this year in chemistry. That question
can then serve as a spring board to discuss seeing vs. observing
throughout the year.

Was there anything specific you'd like to discuss?

Kathleen
