weight by subtracting the tare weight from the gross weight. The net volume was also
calculated by subtracting the intial volume from the final. These calculations were then
used to calculate density by dividing the net weight by the net volume. The densities
obtained for each solid measured was recorded as using the “Volume Displacement”
method. The second part of the experiment was to use the “Direct Measure” method to
find the density of two solids. The students chose to use the glass beads and the
aluminum granular. They measured as accurately as possible the dimensions of each.
Then using the dimensions and the equations of volume for the solids’ shape the students
were able to calculate the volume of each solid. The students weighed each single piece
of the solid and recorded the mass. Once they had gathered both the mass and volume the
students had enough information to determine the density. In order to find the density of
each solid the students divided the mass over the volume. The third part of this
experiment, the students were given a set of pennies. The students recorded the date and
mass of each penny in the table provided. They recorded the mass of each penny to the
thousandth place. After having done this for all pennies, the students took the oldest and
newest penny. The dimensions of these two pennies were taken and using the dimensions
the students were able to calculate the pennies volume and then its density. Then using a
larger graduated cylinder than that used in the first part of the experiment the students
used the “Volume Displacement” method again to determine the density of the density.
The students chose their intial volume to start at 35.0 mL and then after placing the 15
