Friday. October 25th

This post is for last Friday's class. Today we did silent labs. My group got to about 3 labs. The first one we did was the heater with the balloon. We were supposed to hold the balloon to the heater for about a minute with out melting it and observe what happened. The first time the balloon started to inflate but then there was also some static and it followed Seth wherever he went. The second time we did it, it floated up a little bit. The next lab was trying to get the egg out of the beaker. This lab was pretty stinky. But we got the egg out! First we had to put the hot water in and swish it around and then dump it out and then put the egg in the flask and tipped it upside down to get the rest of the water out. Then we had to blow on it and it almost came out, and finally with a helpful hint from Mrs. Sorensen to put the flask in the cold water it finally popped right out! And that's what went down in chemistry on Friday! :)

Today mrs. Sorensen showed the class a few videos about triple point which is a point In time where all of the states of matter exist at once (solid, liquid, and gas). Then we discussed how sublimation happens and some examples of it like air fresheners or mothballs. Next we looked at phase diagram. If the point is below100 it is a solid, if it's at 100 it's a liquid and if the point is above 100 it will be a gas. Then we answered a few questions over triple point. Next we discussed where youbwo
uld want to be if u wanted to boil water fast, Colorado or new Orleans

Happy Mole Day!!

Celebrating 6.02 X 10^23!

Happy mole day!!!! :)

Today is October 24th; one day after mole day. We didn't have school yesterday so we celebrated today. we learned what mole is (6.02 x 10^23). We spent the class period coloring pictures of moles and eating cake and brownies. We also listened to Pandora. It was a pretty fun day in chemistry :)

October 20th, 3rd period chemistry

I'm trying to not make this a very boring blog.... Today we are working with the graphs. Also, we answered questions about the vaporization lab. And, its really cold out.. but I'm over it.. Everybody worked on completing the graph with their partner. it would be great if there were more outlets.. my battery is about to die.. I guess the question of the day that is baffling everyone is... "do we have an assembly?!" but nobody knows(<---- creepy voice..) We are supposed to finish up the graph and questions from home... have a great day.

Today we went over the homework assignment about triple point. Then we did the dry ice lab if we didn't finish last time. Last we worked on the vaporation graph on google docs.

Today is my 1/4 birthday! Today in class we learned about freezing points, boiling points, and phases by doing a worksheet. Then we had time to work on a vaporization graph and Quia quizzes.
