On Monday, we learned about electronegatively and ionization energy. Their trends are the same, they go from the bottom left corner of the periodic table to the top right! Electronegatively is electron-greediness, while ionization energy is the amount of energy it takes to remove an electron.
For homework we had a study guide with over 50 questions to help us review for the test. It was due on block day, Tuesday. After taking the IsATest, which was pretty easy since this is about the 3rd or 4th time we've done this, it was FUN TIMEEEEE!! I've always been fascinated by dry ice because of the effects it give off. Bubbles were blown into a tank and big bubbles were formed from a container having dry ice in it. Who knew carbon dioxide could be so cool?

ATOMS!
Well this week we focused on learning about atoms. Atoms are really really small. We saw a video on powers of 10 which really showed us how small atoms are (and also how big the universe is). There was the Simpsons parody of it that we watched today; that was pretty cool and funny. Earlier this week though, we learned how to tell how many protons, electron, and neutrons are in an atom. The atomic NUMBER shows the number of protons which is equal to the number of electrons. Also, the atomic MASS is the total from adding the number of protons to neutrons! We learned about ionic compounds and what the different groups in the periodic table tell about the elements that are in that column. We did a lot of notes, review questions, and worksheets on all of this.

Because the Units Are So Key
There wasn't any school on Monday, yay! On Tuesday, the classes made a video for the converting units song. That was really fun and we got to watch the video today! I think I looked weird, but the video was really funny and entertaining =) We watched I think it was 4th period's and someone told me about Mr. Olson throwing the eraser by accident but I missed it =( I'm glad we're making another one next week for Milli and her 9 Brothers. We also got little cards of different elements in the periodic table and had to put them together into a chart that made sense and had patterns in it. It wasn't the funnest thing to do, but it wasn't too bad. Today we did something else with those cards, except this time they were all put together in one chart. Chantel and Jessica L were at cross country so it was just me and Jessica G =P We just had to answer a bunch of questions on a worksheet. Until next time!

IsaQuiz and MORE
I didn't get to do my blog post when we were at the library because I ran out of time since I was one of the last people to get tested on measuring mass and volume, but I thought the quiz was okay...a couple of problems stumped me =/ or just one...I registered online for my science book
Yesterday, I missed a lab because of my first cross country meet! The lab sounded really cool and interesting, so I'm sort of sad I missed it, but it's okay I think I'll live =)
