<p>This past week made my head spin. Unit two is all about how.particles move with one another and how their movement affects the system.  I feel the particles were making my head spin. I'm not saying I don't completely understand what were learning  but its hard  to keep all the terms and properties and types if motion. I'm good with facts not terms so I know I'm going to say Something silly on the exam like solids have fluidity or gases have more density than a solid. Okay, back on topic, we learned what makes a liquid driffrent from a gas from a solid. The densest of the three states of matter is a solid which keeps its rigid lattice shape thanks to vibrational motion and they also have the least ammount of energy. Liquids have fluidity and take the shape of their container because the particles aren't connected as closely because of more energy than in solids. Gases have the most energy out of three states because it needs the energy to overcome its barriers and move around. Ok maybe I know.these better than I thought I did. Good thing the assesment is Friday .

W33k 6 ( Wow. cannot believe its been 6 weeks)
W33k 6 Reflection
ChemT3am has reached a milestone. We have completeted chapter one and have moved onto chapter two. I consider it a milestone for everybody and it should be applauded at least because this is validation that we can survive chemistry! ( not that we can't survive :)
We didn't actually start unit two untill later in the week but i think we needed a little transition from one chapter to the next. We started with how particles move in objects and through the air, one of the examples we had was a block of dry ice letting off gas... wait what? how is that possible? because it is made of frozen CO2 and it gets so cold ( cold enough to freeze the water in your hand if you hold it with your hand) that it goes straight from a solid to a gas, skipping the liquid state, or sublimation.The other example we had that day was a bag of popcorn and we raised our hand when we smelled the poporn even though mr abud stayed at the back of the room. The particles moved through the air, but how could we show this in our particle diagrams? We all decided to use arrows to show movement in particles, long arrows for lots of movement, little arrows for less movement.
Another thing we learned this week was how particles in each state of matter ( solid, liquid, or gas)
and that particles are always moving! So its possible, if all the partilces line up right, one could walk through a wall, theroretically, yay science! Another new vocab word we learned was fluidity, or having the tendancy to flow. This can be applied to both a gas and a liquid but not a solid, as solids do not flow, they stay compact and together.
Our first unit 2 assesment is friday, its supposedly 3 hours long, oh boy. wish me luck, im gonna need it.

W33k 4 review chemT3am
W33k 4 Review : ChemT3am,
W33k four was a big w33k for 5th Hour Chem T3am. This week our main goal was to find the density of a person, and furthermore, to find which gender was denser, this turned out to be a very challenging and fun.
On Monday, and Tuesday, we did the planning for the experiment and we figured out how to find the density of a person ( weight converted from pounds to grams, and we used water displacement to find volume, the subjects displaced water in a plastic garbage pail.) We picked subjects ( Maria and Jack) and they were to weigh themselves the night before so we could covert the punds to mass the next day.
Wednesday, oh,boy, that was an eventful day. We actually got to use the emergency shower ( for once) to fill the garbage can that sat in Mr. Abud's plastic kitty pool, which we would collect the displaced water from. Once we had a full ( or as close as we could ger it) 44 gallons we put Jack into the bucket and water rushed EVERYWHERE. I had to take my shoes off and wipe the floor with a lab coat, while this was a nusaince, this was alos a loss of data, which will come up as a point of uncertainty in our conlusion. After the inetial flood, students srung into action, filling two liter soda pop bottles with water to count the displaced water. Jack, in the end, displaced 27, 2 liter bottles, or 54 liters.
Next, we reset the experiment and prepped for Maria to go in to the bucket. Maria, who went in a lot slower, and is a bit smaller than Jack, didn't send water flying out onto to the floor. In the end, she filled 19 and 3/4 2 liter bottles so 38. 5 liters.
Chis Bahr and Harris Bunker recorded this info and put it into a power point presentation, to show the next day.
On Thursday, we all added onto the power point, adding video or pictures, or more information. After we all deemed it complete, we presented our findings, and it turned out ok, ( there were some minor errors) We discussed the success of the expirment as well, even with all of our uncertanties.
Finally, on Friday, we took our second assesment of the year ( andi felt confident about it, hooray)
Whew, big week, but im excited for the next.

W33k 4 Reflection : The week of Two labs
W33k 4
Four weeks, has it been this long already, it feels a lot shorter. Thiss week, per Mr. Abud's suggestion, i will actually really try to expalin, discuss and reflect our two labs this week
On wednesday. we had a sub, so this lab was one we were doing on our own even though Mr. Roberts is a sweet, sweet man. We had to find the thickness of aluminumn foil, of the width of the foil. We concluded as a class that the Aluminumn foil is .0012 cm thick. But what did this mean? was each individual particle that thick, stacked along side one another equally or was it more than one layer? if not, can the particles be any smaller? While these topics are still beign discussed in clas, i predict that while the particles have amaxiumn size they also have a minimum as well.
The next lab we conducted was the lab to figure out the density of a gas. We used the gas created when Alka Seltzer tablets mixes with water. we captured the gas using stange tools but it all worked out in the end . Our gas had a denisty of one g/ ml which was kinda pitiful i believe but the alka seltzer was kidna weak, maybe the gas is really weak?
Together while these labs dont have too much to do with one another i feel that we will tie them together somehow, and relate gas density to aluminumn foil thickness.
While this is not scientific, it is stil lchem related, we voted on shirts this week, i am so excited to find out the winner this week. I really hope it was one of the simplier designs or that we have our names on the back, i think the t-shirts really are like a team. which we are Chem T3am so it fits.
I hope i do well on the unit 2 assesment comming up.
