volume. After having ran the experiment for all metals the students calculated the net 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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
