5. Density = mass / volume Problem statement:
How does the density of a sphere affect its time to be submerged within quicksand?
Determine the density of your objects using the displacement method.
Weigh each of the spheres to determine their mass; then, insert each sphere into a graduated cylinder that is half filled with water. Measure the distance the water level increased within the cylinder to determine the volume. Use the following equation to calculate density:
Density = mass / volume
