Reason For Learning
Some materials like lead, gold, granite and steel are very heavy for their size. Other materials like foam rubber, cork, balsa wood and feathers are so light that huge piles don't weigh much at all. Density measures how much matter is packed into a space. Density determines how heavy a handful of a substance well be and whether it floats or sinks in water.
Learning Intention
At the completion of this lesson students should be able to explain what density is in terms of mass and volume and how it determines how different substances will arrange themselves when mixed together. They should also be able to calculate density of matter.
