Unit 3 lesson 3Presentation Transcript

• Unit 3 Lesson 3 Density
• Remember Matter?
• Matter – anything that has mass and takes up space
• Physical Properties
• Characteristics of materials
• Color, shape, texture
• VOLUME and DENSITY
• Volume
• Amount of space that matter takes up
• Density
• If you know mass and volume of an object, you can calculate density
• Amount of mass in a defined amount of space
• Compare Density of 2 Blocks
• Wood and aluminum
• Same size
• Take up same amount of space
• Same volume
• Different materials
• Different masses
• Compare Density of 2 Blocks
• Heavier block more dense
• Greater mass in the same volume
• 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
• Compare Density of 2 Blocks
• Wood FLOATS
• Aluminum SINKS
• Wood is LESS DENSE
• Aluminum is MORE DENSE
• Liquid Density Column
• Pour liquids that have different densities
• Form liquid layers
Highest density liquid on bottom Lowest density liquid on top
• Density
• Finding Density
• Need mass and volume
• Mass
• Balance scale
• Finding Density
• Volume
• Ruler
• Length x Width x Height
• cm 3
• Finding Density
• Volume
