8. Density Definition: The amount of matter (mass) packed into a given space (volume). A physical property of matter.

9. Density More denseLess dense Ex: ironEx: aluminum

10. More dense = SINK Less dense = FLOAT Oil Water

11. Source: http://gulfblog.uga.edu/ BP Gulf Oil Spill: If the oil leaked from a pipe near the bottom of the ocean floor, how did it end up at the surface? Answer: Oil is less dense than water so it floats.

12. DENSITY = MASS Volume 10 cm Volume = 10cm x 10 cm x 10 cm= 1,000 cm 3 Mass = 2,000 g Density = 2,000 g 1,000 cm 3 = 2 g/cm 3

13. Another Example: V = 10 mL M = 30 g D = 3 g/mL D = M V D = 30g 10mL

18. Density Lab Task: Identify an unknown substance using density. Instructions 1.You have 4 different substances on your tray. 2.Find the mass of each substance using the triple beam balance. 3.Find the volume of the cube using your ruler. (length x width x height) 4.Find the volume of the cylinders using water displacement (Archimedes’ Principle). 5.Find the density of each substance using the formula: Density = mass/volume 6.Use the density chart to find the identity of each substance.

19. WILL IT FLOAT? The density of water is 1 g/cm3 Anything with a lower density will float; anything with a higher density will sink Add an “S” or “F” to your data chart to guess if the object will sink or float, then test your hypotheses. Will it float?
