Today we finally started on our Lab 2E
-Determining the thickness of Aluminum Foil

-We calculated the thickness of a sheet of aluminum foil and expressed the answer with the correct significant figures and scientific notation

-We used 3 pieces of different dimensions of aluminum foil

-Measured the density, the length and width

-From the information and using the formula V=M/D we were able to identify the thickness of the pieces of aluminum foil
Volume song!:


-We learned how to calculate experimental error in %:

(Your answer - Accepted answer)/Accepted answer x 100

Here is a link to a page where it describes this in more detail



REMINDER! next class there is a quiz on this lab so STUDY!

Here is a extra exercise on the Lab we did today:
