2. Unit 3 Lesson 3 Part 1 – Density Overview

3. Remember Matter? 0 Matter – anything that has mass and takes up space

4. Physical Properties 0 Characteristics of materials 0 Color, shape, texture 0 VOLUME and DENSITY

5. Volume 0 Amount of space that matter takes up

6. Density 0 Amount of mass in a defined amount of space 0 If you know mass and volume of an object, you can calculate density.

7. Compare Density of 2 Blocks 0 Wood and aluminum 0 Same size 0 Same volume 0 Take up same amount of space 0 Different materials 0 Different masses

8. Compare Density of 2 Blocks 0 Heavier block more dense 0 Greater mass in the same volume

9. Compare Density of 2 Blocks 0 Place blocks in water to compare densities 0 Sink or Float 0 If it floats, its LESS DENSE 0 If it sinks, its MORE DENSE

10. Compare Density of 2 Blocks 0 Wood FLOATS 0 Aluminum SINKS 0 Wood is LESS DENSE 0 Aluminum is MORE DENSE

11. Liquid Density Column 0 Pour liquids that have different densities 0 Form liquid layers Highest density liquid on bottom Lowest density liquid on top
