  1. Write your response in two sentences What makes an ice cubes float in water ?

  2. Proof that water and ice have different densities

  3. DENSITY Density is defined as mass per unit volume. It is a measure of how tightly packed and how heavy the molecules are in an object. Density is the amount of matter within a certain volume.

  4. https://m.youtube.com/watch?v=SimFy9wOMXY Density Explained

  5. To find the density Mass is the amount of matter that it is in an abject. You find mass by using a triple beam balance to determine the (g) of an object. 1. Find the mass of the object ______ g Volume is how much space an object takes up. You measure volume of a solid by length x width x height. You measure a volume of liguid by using a graduated cylinder. To calculate the volume of an irregular shape, use water displacement. 2- Find the volume of the object Formula for density: 3- Divide Density = Mass Volume

  6. Units for Density • g/cm cubed= density of a solid • g/ml = density of a liquid

  7. Units for density g/cm3 or g/ml Formula: M = mass V= volume D = density M = D x V V = M / D D = M / V

  8. To find density: • Find the mass of the object • Find the volume of the object • Divide : Density = Mass - Volume Ex. If the mass of an object is 35 grams and it takes up 7 cm3 of space, calculate the density.

  9. To find density: • Find the mass of the object • Find the volume of the object • Divide : Density = Mass - Volume Ex. If the mass of an object is 35 grams and it takes up 7 cm3 of space, calculate the density. Set up your density problems like this: Given: Mass = 35 grams Unknown: Density (g/ cm3) Volume = 7 cm3 Formula: D = M / V Solution: D = 35g/7 cm3 D = 5 g/cm3

  10. Liquid Layers – Try on your own • Imagine that the liquids on the right have the following densities: • 15g/cm3 10g/cm3 • 3g/cm3 9g/cm3 • 7g/cm3 12g/cm3 • Match the colors to the correct densities

  11. Review • What is the formula for density? • What happens if you pour together liquids that have different densities? • Will the liquid on the top have the highest or lowest density? • Will the liquid on the bottom have the highest or lowest density?
