Density

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

A physical property of matter.

Density

More dense

Less dense

Ex: iron Ex: aluminum

• More dense = SINK• Less dense = FLOAT

Oil

Water

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.

DENSITY = MASS Volume10 cm

10 cm

10 cm

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 mLM = 30 g

D = 3 g/mL

D = M V

D = 30g 10mL

Answer on your DO NOW handout. The diagram below shows one beaker with oil and water and another beaker with oil and a cork. What would happen if the oil, water, and cork were all placed in one beaker. Draw and label a picture of this. Explain your picture using words like “more dense” and “less dense”.

Homework Density Practice

Density LabTask: Identify an unknown substance using density.Instructions1. 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/volume6. 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 soundsfun!

Marshmallow Man Stations

At each station, complete the task to the poor, poor innocent marshmallow man.
