9/25/08 Today we were finding the mass of different object but we only got to the silver block and the copper cylinder. The copper cylinder was 55.05 grams. We also found out that the silver block was 25.95 grams.
9/26/08 Today we were finding out the mass, height, width,length,and volume of the silver colored block.
10/1/08 Today we finished figuring out the mass, height,width, length, and volume. We also figured out the density for the silver colored block.

10/15/08 Today we are discussing what happened to the cans in the experement. The pressure of the air crushed the can because the pressure inside the can was less then the pressure of the air pushing down on it. Today we are also measuring the mass of one piece of paper, and then the mass of a clump of clay.
10/16/08
Today we are measuring the half ball of clay.

Today we were doing a warm-up that helped us find the density of liquids, then to list them in order from highest density to the least density. It was cool how they seperated into different layers.

States Of Matter
Phillies are solid because they have a strong attraction and the shape doesnt change, and the Phillies are consistant.
Dodgers are plasma because they have no attraction and they move fast and can catch on fire, and the dodgers were hot at the end of the season.
Nationals are gas because they have very little attraction and the nationals move fast so there is no teamwork.
Rays are liquid because they have an attraction but not really strong, for example fighting with each other and have no shape since they are inconsistant. 11-17-2008

When we waved the fan in front of the thermometer the temperature didn't change. For every test the temperature stayed the same, because of this the average was the same (21.5) for every test. Fanning doesnot affect the temperature of the thermometer. As the fan speed increased the temperature stayed the same. The mean temperature with one fan wave is 21.5°c.

Five saftey rules
I No baggy sweatshirts or sleves.
II Tie your hair back.
III Wear saftey goggles.
IV Put the wire to the temperature sensor behind the pegboard.
V Hold the match up so you don't burn yourself.

we learned that wood has chemical potential energy. when a book falls to the ground it has kinetic energy. the batteries have chemical energy that can be used to light a lightbulb.

In our observaion of day two, we discovered the steel wool tube had a slight bit of rust lodged in it. The water level also increased by 10 mL. The control stayed the same amount of water.
4-1-09
The amount of rust didnt change. However, the waterlevel rose 5 mL. The control didnt change.
4-2-09
the controled test tube water level went up by 5 and the steel wool test tube went up by 10.

the the amont of rust still didnt change even after 5 days of observation. the amount of water did change in both of the test tubes.
