  1. Density Why some things sink and others float

  2. Rainbow Lab

  3. Rainbow Lab

  4. Rainbow Lab

  5. What if I finish early? Calculate the density of the cubes on lab station #8 using the equation: Density = Mass Volume

  6. Rainbow Lab Analysis Red Orange Yellow Green Blue

  7. Density How much “stuff” is in a certain space.

  8. MISCONCEPTION ALERT Density Weight

  9. Which object weighs more? Which object is more dense? Density of water = 1.0 g/cm3 Density of gold = 19.3 g/cm3

  10. Density How much matter (mass) is in a certain volume m d V

  11. d V Think about your knowledge of fractions from math class Let’s see what happens when we change one variable m

  12. If mass gets bigger… 40 kilograms 20 kilograms What happens to density? …and volume stays the same

  13. …and mass stays the same 20 kilograms What happens to density? If volume gets bigger…

  14. If mass gets bigger… 40 kilograms 20 kilograms …and density stays the same What happens to volume?

  15. What happens to mass? 10 kilograms 20 kilograms If density gets smaller… …and volume stays the same

  16. Sink or float?

  17. Sink or float? Water has a density of 1.0 g/mL. Therefore, any object with a density of LESS than 1.0 g/mL will FLOAT in water. Anything with a density of MORE than 1.0 g/mL will SINK.

  18. Layers Why did the colors in rainbow lab work when we used the same materials for each color?
