Part 1 – Density Overview

Remember Matter?

0Matter – anything that has mass and takes up space

Physical Properties

0Characteristics of materials0Color, shape, texture0VOLUME and DENSITY

Volume

0Amount of space that matter takes up

Density

0Amount of mass in a defined amount of space0 If you know mass and volume of an object, you can

calculate density.

Compare Density of 2 Blocks

0Wood and aluminum0Same size

0 Same volume0 Take up same amount of space

0Different materials0 Different masses

Compare Density of 2 Blocks

0Heavier block more dense0Greater mass in the same volume

Compare Density of 2 Blocks

0Place blocks in water to compare densities

0Sink or Float0 If it floats, its LESS DENSE0 If it sinks, its MORE DENSE

Compare Density of 2 Blocks

0Wood FLOATS0Aluminum SINKS0Wood is LESS DENSE0Aluminum is MORE DENSE

Liquid Density Column

0Pour liquids that have different densities

0Form liquid layers

Highest density liquid on bottom

Lowest density liquid on top
