smell lab

this week we didn't do much, because there was just 3 days of school, 2 days of class.
we did a lab with drawing the molecules.
we also had a worksheet for hw involving the lewis dot structures.
i finished in class, so no hw for me in chem.
we also did something where we smell different things and record what they smelled like.
some were fishy, some were sweet, and some were minty.
i couldn't really smell it out.
i just smelled them and most of them were disgusting smelling.
that was the two days of class.
today is thanksgiving and i'm gonna eat some turkey!

lewis dot stuff

we did a lab on the lewis dot structure.
we made bonds with balls and sticks.
we also had to draw it.
gilbert newton lewis's element symbols are based on the # of valence electrons.
honc 1234!
some elements from lone pairs, but not carbon and other elements in group14.
group 14 elements can form 4 bonds, the maximum number of bonds that an element can form.
now i'm gonna go do a molecule web page.

i got vanillin.
now i have to work on it.
