Density Lab
Purpose:
The purpose of this lab was to demonstrate different methods of measuring
density both in regular and irregular objects.
Data:
Density Formula
–
D = M/V
Observations:
•
The domino had 12 dots.
•
The dots on the domino are carved into the domino, which changes both the mass
and the volume of each of the different numbers on the dominoes.
•
The formula used to calculate the volume of the domino is the volume formula for
a rectangular prism.
The domino is not a perfect rectangular prism because of its
divots and rounded edges, which causes the volume to be not perfectly accurate.
•
The curves and angles of the gummy bear made it impossible to get accurate data
by trying to measure it with a ruler.
•
The gummy bear sank, which makes sense because its density is greater than that
of water (1g/cm³)
Conclusion:
Density is easily calculated by using the equation D=M/V.
Before
calculating the density of an object, you must first find the mass and volume.
