salt crystals and finals

this week, we looked at our salt crystals from the lab last week.
i got extra credit!
it is also finals week.
i'm gonna have to study a lot, even though i don't want to.
it's only tuesday.
i'm posting this blog today because i won't have time to do it later in the week.
today we are in the computer lab, because we have to study for the chemistry final.
i heard it was pretty easy, but it think i'm gonna do bad so i gots to study more!!!
i'm not gonna blog too much this week because i need more time to study.

mole stuff!

we did a lot of stuff on moles this week.
we did worksheets.
yesturday, we weighed hole punches.
hole punches were everywhere!
all around the school!
they were very colorful and pretty!
the group that got the closest to the amount given got extra credit!
i didn't get the extra credit.
we also looked at power point slides.
to learn about the mole, we watched a video with mr. olson and his friend curtis.
it was a fun video!

attractive molecules lab

this lab was about polarity of different liquids.
there was water, acetic acid, isopropanol, and kerosene.
we charged up the wand with some wool.
then we saw if it reacted.
everything reacted besides the kerosene.
the water would move left of right or in whichever opposite direction of the wand.
yesturday we read a comic and have to answer questions.
it was polar bears and penguins.
today, i am posting this blog.
that was mainly the entire week.

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.

properties of metals lab

we did a lab this week about bobby pins.
we burned it, then dipped it in water to cool it.
then we looked at the result.
some broke and some stayed the same.
the lab took two days.
today, we are going to create a molecule web page.
i got vanillin.
now i have to work on it.

spectrum stuff

this week, i remembered that we did a lab with a machine thingy.
we had different colors in test tube and we put it in the machine.
then we record the number.
during this lab, we also looked at the color of chalk as we changed to number on the machine.
we had to take notes and do worksheets this week as well.
we looked at power point slides too.
that's all i remember. it was a long week.
