  1. Chapter 3, Section 3 Pg. 82 Floating and Sinking

  2. How can I figure out if it’s real? What’s this? the water rises when I get in!!! Hmmm… The crown has silver in it and gold is pure! Same Weight and Volume? Archimedes’ Story

  3. Archimedes’ Story • When you place an object in water, the rise in water is due to ______ ___________. • Density depends on 2 things, __________ and ___________. • Density is the reason objects _________ or _________ in fluids.

  4. Volume

  5. Density • To figure out the Density of an object, divide the object’s ________ by it’s __________. • ___________ is how much space something takes up. Density = Mass / Volume

  6. The Density Triangle • Density = mass per unit volume • Per means divide! • Unit means a single amount. M D V

  7. Same Volume Different Mass Different Volume Same Mass Density

  8. Density Does greater volume or less mass make Diet Coke float? How do you know?

  9. Density • If an object is More dense than the fluid it is in, it will _________. • If an object is Less dense than the fluid it is in, it will _________. • If a block of wood has a mass of 200 grams and has a volume of 4 liters, what is its density?

  10. Dive Dive!! More Dense Density Less Dense

  11. Buoyancy (Boy – unsee) • Water exerts a force called the ___________ force on submerged objects. • What does submerge mean?

  12. Buoyancy The buoyant force on a object is equal to the weight of the fluid displaced by the object. If they have the same mass why does one sink and the other float?

  13. Buoyancy • Buoyant force acts in the ________ direction, against the force of __________, so it makes an object feel ________.

  14. Density Review • Why does a balloon filled with helium rise in air? • Why does an ordinary balloon fall in air? • How do submarines dive into and rise out of the water?
