Todays' class was relively easy. We started out class by quickly changing seats and getting new lab groups. Then people signed up to do the blog for the next two weeks. Also Mr. Henderson mentioned we will be starting a new unit thursday. Then Mr. Henderson explained the homelogic issue where the final grades were very low and wrongly posted; they are now fixed. There is also a 5% curve on the final grade.

We then talked about signing up for courses next year as well as science electives that we are elegible to take. Mr. H explained the 5 electives; Medical Technologies(which is for people who are looking to go into the medical field, a little like house), Forensic Science(which is for people that are interested in CSI), Horticulture ( which is about plants, and anyone with a pulse can pass with an a), Brain Studies(which i for people who would like to be in the counciling and psychiatry fields of medicine) and last but not least astronomy (which Mr. H reccomends we take senior year after physics).

After that talk we went over a new topic that we have a webassign as homework tonight on, Chapter 9 states of matter. Mr. H explaines mostly the names of the changes in matter, liquid to gas, solid to liquid ect. but he also mentions that gas has no orderly arrangement, has translational and vibrational motion and no intermolecular forces. Which basicly means we can walk through gas without even feeling it and one gas particle can go from one end of the room to another without a problem. Liquid also has no orderly arrangement, it has as well translational motion and vibrational motions but, differently from gas, it has a weak intermolecular force. That means that even though it shapes to its container it almost always comes together, so if we so a karate chop through it, it will come back together. Solids are a whole different factor, they have a vary orderly arrangement of particles, NO translational motion(only sometimes vibrational) and they have strong molecular forces. That means that solids are one shape and if we do a karate chop through it, its going to hurt.

After our quick lesson Mr. H gave us a data sheet and we were sent off to the computer lab to do graphs based on the data he gave us. That is lab TC9 and i will provide a picture of all the nessesary objectives we need to do and answer.

At the end of class Mr. H gave us a print out of our semester one grades. That was the end to a very lovely chemistry class.
