    Hi everyone
    I love the glue-ball idea for the first day of chem class. I've also
    done a similar activity with cornstarch and water demonstrating change
    from liquid to solid depending on whether you are slowly stirring it or
    sharply hitting it. Also another good observation first day is
    mothballs in a tall graduated cylinder with CaCl_2
    and HCl ...then have the students oserve what happens ...good
    observation vs inference!
    I've been watching for postings but havent seen any new ones since the
    last class in Jan.
