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

Density More dense Less dense Ex: iron Ex: aluminum

More dense = SINK Less dense = FLOAT Oil Water

Answer: Oil is less dense than water so it floats. 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. Source: http://gulfblog.uga.edu/

DENSITY = MASS Volume Volume = 10cm x 10 cm x 10 cm = 1,000 cm3 Mass = 2,000 g Density = 2,000 g 1,000 cm3 = 2 g/cm3

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

AGENDA Agenda Density Cubes/Cylinders Lab Calculating Density Practice Homework Density Practice

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

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?

Marshmallow Man Lab What are we doing in Science today, Mrs. Gaffney? Oh Marvin, you don’t want to know….

Making Your Marshmallow Man Insert a toothpick halfway into the flat side of one large marshmallow to form the body. Stick the second large marshmallow on the remaining end of the toothpick to make the head. Insert four toothpicks into opposite sides of the body to make his arms and legs. Place the small marshmallows on the ends of the toothpicks to make hands and feet. This sounds fun!
