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.
