Overview
Throughout the week, we did multiple labs and experiments.
 Monday
On Monday, I was absent so I don't really know what we did but I know it involved having a student lay on a trash bag and having other students blow into the corners.

Tuesday
On Tuesday, we did a lab called "Pressure vs. Volume" and we hooked up a syringe to a gas pressure sensor and changed the volume to see how the pressure changed. We also graphed the results.

On Monday we did multiple activities that looked at density. The first thing we did was look at how liquids of different densities settle when combined by adding different food colorings to different liquids and mixing them. We also whiteboarded the problems from worksheets on volume, density, and mass. Also we started a worksheet on applied density.
On Tuesday, after completing worksheet 4, and we did a lab on gas density. We discussed how to find the mass and volume of a gas, and discovered that gas is less dense than water. And because we knew the volume, we can find the mass and density.
On Wednesday, we discovered that the gas from the experiment on Tuesday is 600 times lighter than water. For the remainder of the class, we worked on the worksheet of applying density to study for the quiz on Tuesday.
Thursday we quizzed on applying density. Afterwards we found the thickness of regular and heavy duty aluminum foil.

Last week in class we mostly did stuff on how to use the mass and density to determine the volume or vice versa. We also did multiple worksheets on how to read the mass versus density on a graph and use that info to determine the volume. Although I was gone Friday so I'm not quite sure what we did throughout the entire week but I know what happened Monday through Thursday.

First was a worksheet on using the info on a graph to volume, density, and mass of certain metals. Thursday we had a quiz on what we learned and it was mostly on how to read the info on the graph and how to use that info to find other things.

This week in class we did a lot of stuff involving mass and volume and the relationship between mass and volume. We also did a couple experiments of how cubed centimeters relate to volume.

The first experiment we did was filling a  clear plastic cube with water (approximately 4 in X 4 in) and we had to measure the water in centimeters so that means getting the height, width, and length of the water. The next step was to figure out the volume of the water in cubed centimeters and then use a graduated cylinder to find the exact milliliters of the aforementioned water. After doing the same thing five times with varying amounts of water, we were able to graph the data and see how accurate we were with our math and our measurements.

The second experiment all about the relationship between mass and volume and it started with us taking the mass of five steel rods, five aluminum rods, and five acrylic rods for a total of fifteen measurements and then we took the volume of each of them. After recording all our data, we used the laptops to graph it and it showed us and exact graph that completely cut out the human error factor. Then we printed the graphs and taped them in our notebooks.

Afterwards, toward the end of the week we started working on a packet titled "Mass, Volume, and Density" and it dealt with exactly that, and showed us the difference between the three. It also gave us figures with different sizes, different sized particles, and asked us to compare the mass, volume, and density.
