The Dynamic Density Kit is a density experiment used to teach children how to measure volume and introduce the concept of density in an easy and fun experiment.
Density is the amount of mass an object has per unit volume at a specific pressure and temperature. In determining density, it is necessary to calculate mass and volume as well. Mass is the amount of matter in a particular object. It is measured in grams. Volume is the amount of space an object occupies.
The volume of a solid is measured by determining how much water an object displaces. To calculate the displacement subtract the beginning volume in the cylinder from the final volume (volume with the object in the cylinder).
To determine density, mass is divided by volume. Since the purpose of the density experiment is to determine the density of different metals, the experiment will require determining the mass and volume of several objects and using simple arithmetic to determine density.
