Hello and welcome back. I hope your thanksgiving day break went well and you all ate heaping handfuls of food and good cheer. Though, I know you can't really eat cheer.
Today in class we finished off our Chemistry Notes Part 2. Looking at covalent bonds and the wonderful properties of water, I showed a couple of demo's the helped solidify how chemical bonds are formed and broken. We should have understood that energy is needed to make or break chemical bonds, and often times, when you use a small amount of activation energy, we can often get out more energy than we initially used. This is the case with the human body's breakdown of glucose molecules for energy.
Refer to the last post on where to download the powerpoint and note sheet if you weren't here for either.
Tomorrow, we're going into the lab to look at the cohesive properties of some chemicals and then we'll test on Friday.
I repeat: TEST ON FRIDAY!!!

Monday/Wednesday, November 22 and 24th.
The date's a little screwy because we had a snow day.
Today in class we started talking about valence electrons and the types of bonds atoms form. It's important that we know and understanding molecular bonding, because that affects a lot or our bodily processes and will great increase our understanding of cellular actions.
The key to understanding bonds is valence electrons. Remember, valence electrons are the outer most electrons in the outside shell. The group (column) on the periodic table tells you how many valence electrons an element will have. this will in turn tell you what type of ion it'll form when we're talking about ionic bonds.
Covalent bonds a different because instead of an electron being transferred, the electrons are shared with amongst the atoms.
Download that powerpoint notes here: ICB Atoms, Valenece Electrons and Bonding.
You can download the second note sheet here if you weren't in class: Second Note Sheet for Atoms
We're going to dive (no pun intended) into water chemistry to really understand the cells and how they work.
Until next time, have a great Thanksgiving.

Wednesday/Thursday, November 17/18th
Today we warmed up our brains with a few logic puzzle brain teasers.
We then looked at Isotopes and how to find the number of neutrons in certain atoms of certain types.
We then went over our notes, which you can download here: ICB NOTES FOR ATOMS: PART ONE
We then did an Atom worksheet for practice, involving locating elements, atomic numbers and atomic mass/weight on the periodic table. You can download the sheet HERE.
If you didn't do the worksheet in class, you should really download it and work on it at home.
Understand that Isotopes are different types of the same atom. The only thing that's different is the number of neutrons in the nucleus.
Friday remember is a short day with only 20 minute periods.
Until next time,

Monday/Tuesday, November 15th and 16th
Welcome Back! I hope everyone had a wonderful little break. Now it's time to get back into SCIENCE!!!
Wednesday was fun looking at the different reactivity (how quickly an element will engage in chemical reactions) of the different period 3 metals (Aluminum, Sodium and Magnesium). We saw a nice fire and explosion with our Sodium/Water reaction.
Today we talked about what was happening. How Sodium was losing an electron and its similarities to the other alkali metals. We watched This Video, explaining how each alkali metal becomes more reactive with water as we move down the periodic table.
Of course, this is the exact opposite of the halogens. The group 7 (or 17) halogens get more reactive as you go up, with Fluorine being the most reactive. That's because it is the most aggressive electron taker.
REMEMBER, it's the electron configuration that will tell how a chemical will react.
I then collected your Elements II lab, so, if you didn't turn it yet, do so as soon as possible. Grades come out this week and I need everything in.
We then dove back into our notes about basic atomic structure and how they're are arranged on the periodic table.
We looked at the Atomic # and saw how it was different from the Atomic Weight or Atomic Mass. We made answered questions about how many protons, neutrons and electrons would be found in certain elements.
You can read all this again if you missed Our notes the first time by clicking this link.
We're going to next look at valence electrons, ions and water. These three key concepts will make understanding the chemistry of the cell much easier.

Short periods today.
We finished off our Element Lab with Station Number 9, where I showed you similarities and difference in the alkali and alkali earth metals.
We put Calcium (Ca) and Sodium (Na) into water to watch them catch fire, and we compared how Aluminum (Al) and Magnesium (Mg) burn or don't burn.
Next week we're going to continue our exploration of the periodic table and its periodicity.

Monday/Tuesday, November 8th & 9th
Hello and I hope your weekend went well.
Today we finished up the lab we started on Friday, exploring elements. You should have all 8 stations filled out and the lab should have been turned in today.
We came back in to the classroom and I gave you your HOMEWORK; a 5 page packet reading about the periodic table. If you didn't get in class, you need to see me after school to pick one up. We will have a reading quiz over the reading next class period, Wednesday.
If you weren't in class to receive the packet, you can get the same basic information from this wonderful website: http://www.chemicool.com/ Check it out, a lot of really neat and great information.
We next went on to the crux of our unit, learning about the atom.
I handed out the first notesheet for this unit. You can download it: Atom Notesheet One
And, to go with that wonderful notesheet, download the powerpoint presentation as a .pdf right here: Atom Notes, set one
That should get you a lot of the information you need.
Tomorrow in class we'll do a fun demonstration to show how atoms are related in the periodic table and, if there's time left over, talk about what makes chemistry so cool.

November 4th and 5th, Wendesday/Thursday!
TEST DAY!!!! Wooohhooooo. Today we tested over our latest unit, Cosmology and Star evolution. Hopefully you all studied and were met with success on the test. We'll find out when I hand them back tomorrow.
Our next unit is ATOMS and Chemistry. It's a biggie, with a lot of information to go over. It'll be important to stay focused and take good notes.
Remember, atoms are small and they're everywhere. We can't really see them, so scientists have to create models that we use to find out about them. So far, the models we've been using have verified all our observations and predictions.
You'll get to know and love the periodic table over this unit. Here's a quick picture of one and how to read it:
click on it to see it bigger.
Tomorrow we're going to do our introduction to elements lab. Basically we get to explore elements and certain elemental properties.
See you then!
