Presentation Transcript

  1. Density

  2. Density • Density – measure of how much mass is contained in a given volume • Amount of ‘stuff’ inside an object compared to how big it is

  3. What’s more dense? • Foam roller or steel bar? • Baseball or hacky sack?

  4. Calculating Density • Density = Mass / Volume (mass divided by volume) • Density = g/cm3 • Density of water = 1 g/cm3 • How do I determine if something sinks or floats in water?

  5. Sink or Float? • If the density is greater than water (>1 g/cm3), object will sink • If the density is less than water (<1 g/cm3 ), object will float

  6. Density of Liquids • More dense liquids sink, less dense liquids rise Youtube Example

  7. Calculating Density • Remember when you found the mass and volume of those 4 blocks earlier this week? Now calculate their density. • Iron: • Brass: • Aluminum: • Lead:
