Density Lab

In the density lab we recorded data of the mass and volume of 4 different sized cylinders of a specific material.  To measure the mass we used an electronic balance.  Then to measure the volume we used graduated cylinders and used water displacement to figure out what the volume of the material was.

Honey has a density 1.432 g/cm cubed, soy sauce has a density of 0.980 g/cm cubed, and olive oil has a density of 0.914 g/cm cubed. (The order of the densities goes from bottom to top) The reason the liquids separated was because after the sauce was left alone, the contents broke down and separated by the densities. Also another thing that could have contributed to this factor was because it was in the fridge which could have speeded the process of separating.

In my opinion, I think that they have done a good job in sealing the gash in the well (from the BP oil spill).  Now that it is closed there is no more oil spilling out in the Gulf of Mexico.  Although, that still doesn't mean that all of the oil is cleaned up yet; 53 million gallons of oil still remain.  And since it is trapped in marshes it makes it harder to clean up.  So overall, I think that they have done a poor job in trying to clean up the spill because they know it is there, so why didn't they start cleaning it right away?

There are so many things that I would like to accomplish this year academically. One thing I want to do is figure out what class excites me the most. This way I can use that class and make it my profession. Another thing I would like to accomplish is get straight A's in all my classes. I would also like to make sure that I take better notes in my classes, so that when it comes back to study for a test I am prepared for it. The last thing that I would like to do is to not be afraid to ask the teacher for help; whether it means to email my teachers or talk to them directly during, after, or before class.
