Density

Mr. Andersen explains the concept of density, a measure of matter's compactness, using various examples and a PhET simulation. He demonstrates how density is calculated by dividing mass by volume and shows how different materials have varying densities. The video includes practical examples, such as comparing a bowling ball and a volleyball, and uses a PhET simulation to calculate the density of materials like Styrofoam, wood, ice, and aluminum. The video concludes with an experiment using water displacement to determine the density of objects.

What is the significance of the equation density = mass/volume?

Compare the densities of a bowling ball and a volleyball and explain the difference.

What happens to the density of ice compared to water, and why does it float?
