Measuring Matter

Measuring Matter. MFMS. Mass vs. Weight. Mass- a measurement of how much matter an object contains Weight- a measurement of the force of gravity on you What is the difference? Weight will change on different planets, when the force of gravity may be more or less. Mass stays the same.

  1. Measuring Matter MFMS

  2. Mass vs. Weight • Mass- a measurement of how much matter an object contains • Weight- a measurement of the force of gravity on you • What is the difference? Weight will change on different planets, when the force of gravity may be more or less. Mass stays the same.

  3. Volume of Regular Objects • Volume- the amount of space an object takes up • Solids, liquids, and even gases take up space • Length x Width x Height is the formula for rectangular objects • Unit= cm3

  4. Volume of Irregular Shaped Objects • Since “irregular” shaped objects are difficult to measure, you can find their volume by WATER DISPLACEMENT • How does water displacement work? Put the object in a graduated cylinder containing water and measure how much the water level rises. • 1 ml= 1 cm3

  5. Density • Different substances may have the same mass, but they don’t necessarily share the same volume….. • Density-the measurement of how much mass is contained in a given volume • Formula: Density = Mass__ Volume

  6. Density Video Clip

  7. Video Clip Questions • Each kind of substance has its own density. How is this helpful to scientists? • What is the density of water? • Objects with densities greater than water will ________. • Objects with densities less that water will ________.
