Hmm...
I never even thought of that Ray. Wow! Teaching chemistry for 39 years.
Bless your heart! I will consider that. It does make sense. They do not
use much of the measurement and sig figs until they get to the mole and
conversions. Thanks!

Subject: [Channel-talkchemistry] Re: starting the year
In response to Jeff Bulgrin's question on how to start the year, I feel that
most all chem texts lead off with the boring stuff like measurement and
scientific method or defining chemistry; yet the kids at the beginning of
the school year are psyched up for something new and challenging [but not
too challenging]. After experimenting with a variety of topics and
techniques for 39 years, I find that by starting on day one with magic
tricks that introduce chemical compounds and reactions we can go right into
writing formulas and balancing equations which is the most interesting part
of chem for kids. The first few labs can deal with formulas and reactions
and some of the most spectacular demonstrations [magic tricks] can be
repeated later in the course [to their delight] with a more in-depth
explanation. This might mean you start with chapter 5, but so what... you
can come back to visit measurement and sci. method when it is actually used.
