Pennium lab

INTRODUCTION:
For the pennium lab we were trying to figure out atomic mass and how it was derived. To do so we made our own measure, the CMU, and used it to measure coins. The point of the lab was for us to be able to learn how scientists developed the system for AMU's.

HYPOTHESIS:
Our hypothesis was that we would be able to use all of the materials that we had, and use different equations to make our own unit of measure, the CMU. we also thought that it would come out being a weird thing that didnt work very well... but that it would be a complicated problem to figure out.

MATERIALS:
The materials that we used in this lab include:
About 10 pre-1982 pennies
About 10 post-1982n pennies
A nicke
A dime
A quarter
The triple beam balance, and a calculator

PROCEDURES:
Our procedure was that we first separated the pennies into pre 1982 pennies, and post 1982 pennies.
Next we measured, and recorded the mass of the pennies, bye dividing the weight, by how many there were!
We then measured the mass of the nickel, the dime, and the quarter, and recorded them on our lab.
After that we answered some questions about the lab, and how it worked, and then used the information that we had, and organized it into a table, and used it to calculate the equation for CMU.
After that we answered some more questions about the lab, and that was all....

DATA:
These are the data tables that we made for our lab, on excel, to help us organize the info that we got to help us use the equation!



                                                                                                                  Dimes

Pre 1982	Pre 1982	Post 1982	Quarters
Average Mass (Grams):	3.101	2.49	5.39	2.23
% of Pennies:	45%	55%	N/A	N/A
Relative Mass (CMU):	0.63	0.5	1.09	0.47

DISCUSSION:
Our data tables helped us see what the mass of the pennies, and other money according to the nickel. we could then use the information in the data table to put into our equation and figure out the CMU.

CONCLUSION:
Our hypothesis was mostly right, other than it really wasnt as hard as we thought that it would be, it really worked quite well, and we were able to do what the lab was meant to do! we found that there was a lot of info that we really needed to be able to figure out the CMU, but it really wasnt more than just figuring out the mass of the objects, and simply adding subtracting, multiplying, and dividing. This lab helped us to learn how scientists actually use and find equations. and really helped us appreciate what they do.
