Unit 3 lesson 3
- 1. Unit 3 Lesson 3 Density
- 2. Remember Matter? Matter – anything that has mass and takes up space
- 3. Physical Properties Characteristics of materials Color, shape, texture VOLUME and DENSITY
- 4. Volume Amount of space that matter takes up
- 5. Density If you know mass and volume of an object, you can calculate density Amount of mass in a defined amount of space
- 6. Compare Density of 2 Blocks Wood and aluminum Same size Take up same amount of space Same volume Different materials Different masses
- 7. Compare Density of 2 Blocks Heavier block more dense Greater mass in the same volume
- 8. Compare Density of 2 Blocks Place blocks in water to compare densities Sink or Float If it sinks its LESS DENSE If it floats its MORE DENSE
- 9. Compare Density of 2 Blocks Wood FLOATS Aluminum SINKS Wood is LESS DENSE Aluminum is MORE DENSE
- 10. Liquid Density Column Pour liquids that have different densities Form liquid layers Highest density liquid on bottom Lowest density liquid on top
- 11. Density
- 12. Finding Density Need mass and volume Mass Balance scale
- 13. Finding Density Volume Ruler Length x Width x Height cm 3
- 14. Finding Density Volume Graduated Cylinder
- 15. Density Problem Paperclip has a mass of 9g and a volume of 3mL What is its density?
