Density and Flotation
• Task: Given 3 eggs, salt, water, and 3 beakers, make it so that one egg sinks, one egg floats and one egg stays suspended in the middle of the water.
• Objects sink or float based upon density.
• If an object is less dense that water (p < 1g/cm3) it will float.
• If an object is more dense than water (p < 1g/cm3) it will sink.

Object Density (g/cm3) Sink or Float
Aluminum 2.7 g/cm3
Penny 7.2 g/cm3
Gold 19.3 g/cm3
Wood 0.85g/cm3
Sugar 1.6g/cm3
Ice 0.917g/cm3
Baby Oil 0.83g/cm3
Mercury 13.94g/cm3
Will a penny sink or float in liquid mercury?

QUIZ: make an 8 item density column.
7 Layer Density Column
Object Density g/cm3
Honey 1.42
Light Corn Syrup 1.33
Dawn Dish Soap 1.06
Water 1.00
Vegetable Oil .92
Baby Oil .83
Rubbing Alcohol 0.79
You must use 3 solids!Hand in a labeled picture in COLOR! Bring it in for extra credit!
Objects generally sink or float based upon density. • More dense = sinks• Less dense - floats

How much of an Object will Float above Water?
Zinc
0.92g/cm3 7.13g/cm3
The zinc will sink as its denser than water
The ice floats as its less dense than water
But how much is underneath the water?
If 92% is under water then the other 8% is visible!
ICE CUBE
About 8% visible

Just the Tip of the Iceberg!!!

90% of this ice berg is below water (salt water)

Most of an Iceberg is below water!
Think about this and ships traveling in the
ocean.

Flotation Problems (Handout)
Knock on Wood
• A branch snaps and falls into a river. It has a density of 0.7g/cm3, will it sink or float and if it floats how much of it will be visible?
Floating Basketball
• A basketball has a mass of 624g and a volume of 7512cm3. What percentage of a basketball will be visible above water?
