King Henry Fable
King Henry was an old English king who loved to drink
chocolate milk. Even though metrics had been used in
England for a long time, King Henry had difficulty
converting between the different metric units. He had
really become frustrated and confused when he went to
get himself some chocolate milk. He did not know how
much milk to pour himself. He felt, as a king, that he
should be able to do anything. So he asked for help from
all of the smart people in his kingdom. They all tried hard
to explain to the king, but without a lot of luck. Then one
of the great mathematicians in his kingdom came forward
to try his luck.
However, before he could explain to King Henry that
everything in metrics was done by either multiplying by 10
or dividing by 10 which is easy to do by just moving the
decimal point, King Henry died by drinking chocolate milk.

King Henry Died By Drinking Chocolate Milk
King Henry died by drinking chocolate milk.
He drank 1 kiloliter in his robe of silk
1000 liters were more than he could take
1 million milliliters turned out to be a big
mistake
A princess in a traveling band
Passed through King Henry’s land
She had a gift that he’d never seen
She said that it was chocolate milk
And the King drank one drop just to try
1 milliliter is not a lot
But poor King Henry just could not stop
Chorus:
King Henry drank 1000 drops
1 liter’s not a lot
It barely filled up his royal crown
He continued to keep drinking on
‘til 1000 more liters were gone
A bathtub full of chocolate milk
Drowned King Henry in his robes of silk
King Henry died by drinking chocolate milk.
10 millimeters equals 1 centimeter
100 millimeters equals 1 decimeter
1000 millimeters equals 1 meter
We’ve got to keep going, we just keep getting
bigger
10 meters equals 1 dekameter
100 meters equals 1 hectometer
1000 meters equals 1 kilometer
In the metric system that’s the way that we
convert
Millimeter, centimeter, decimeter, meter
Dekameter, hectometer, kilometer – LENGTH
Milligram, centigram, decigram, gram
Dekagram, hectogram, kilogram – MASS
Milliliter, centiliter, deciliter, liter
Dekaliter, hectoliter, kiloliter - VOLUME

• Quarks are very very small
• Molecules are around the billionths of a meter in size. That
is 0.000000001 meters. Some molecules are smaller and
some bigger, though.
• People are a little over a meter tall,
• Mountains are kilometers in size.
• The Earth is megameters in size (a megameter is a thousand
kilometers, and the Earth's Diameter is actually 12,000 km)
• A Light Year is about 10 petameters in size (a petameter is
1,000,000,000,000,000 meters, which is a 1 followed by 15
zeros)
• The Milky Way is about 1 zetameter across
(1,000,000,000,000,000,000,000 meters, which is a 1

What is the Density of Water?
Mass of Graduated Cylinder & Water = ______ g
Mass of empty Graduated Cylinder = -______ g
Mass of Water only = _______ g
Volume of Water = ÷ _______ ml
Density of Water = _______ g/ml
DENSITY OF WATER ~ = 1!
If an object has a density greater than > 1, then it will SINK!

Why did some objects
float and some
objects sink?
Density
Definition: the amount of matter packed into
a space
Both rectangles take up the same amount of
space. Which one has a higher density?
Why?
Drag these blocks in order from the least dense to the
most dense.
Vertical Order
Objects that are most dense
sink to the bottom. Objects
that are least dense will
float to the top.
Hot Air
More energy, molecules are moving faster
Molecules are more spread apart
Which sample shows warmer air?
YOU: COMPLAINT
DEPARTMENT
You just landed your first job! Employed by
Coca Cola, you work in the complaint
department responding to customers.
Employees must respond to customers with
a letter. Write a letter responding to this
lady, Mrs. Angrybird.
To Whom It May Concern:
I have been drinking Diet Coke for a long time! In fact, I
have been drinking it as long as I can remember!
Recently, my husband and I went on a fishing trip. (He
drinks regular Coke.) We had a cooler of Coke (for him)
and Diet Coke (for me). The cooler accidentally fell into
the lake. The Diet Coke cans floated away, and the Coke
cans sank! I not only was angry that I lost my Diet Coke,
but I am furious that you put less soda in Diet Coke than
you do in regular Coke! I pay the same price for soda as
my husband! This is ridiculous! I want a refund!
Mrs. Angrybird
Formula to Figure
Density
Density has its own measurements. The
formula to find density is mass divided
by volume.
Put your finger
over whatever
term you are
trying to figure
out.
D of Water = 1!
D > 1 = SINK!
D< 1 = Float!

If you are ever asked to draw an object in water according to its’ density, here’s
how:
1.
Remember these helpful hints…
1
• The Density of Water is = to ___.
• Anything that ______
floats has a Density less than < 1.
sinks
• Anything that Sinks has a Density _________
than > 1.
mass
2. Calculate the Density of the object by using the formula Density = ______ ÷
___________
volume
3. To figure out where the object will settle in water follow these simple rules…
• If the Density of the object is greater than > 1, then the object sinks in the
water – down to the ___________!
bottom
• If the Density of the object is equal to 1, then the object floats in the
middle
__________
of the water.
• If the Density of the object is less < than 1, then convert the density into a
_____.
The percentage that you calculate is how much of the object is
%
submerged
___________
in the water. The remaining percentage to equal a total of 100%
showing
is the amount of the object that is __________
out of the water.
• For example, the density of a certain object = ___
.8
• To express it as a percentage would be 80%, so 80% of the object would be
below
20% would be above it! Here is a picture of

Does all wood float in water?
• Ironwood is a name applied to many species of hardwood
trees, the wood of which is so dense and heavy that it
sinks in water. North American ironwoods include the
American hornbeam, the mesquite, the desert ironwood,
and leadwood (Krugiodendron ferreum).
• Water has a specific gravity, or relative density, of 1. To
sink in water, a substance must have a specific gravity
greater than 1. Leadwood has a specific gravity between
1.34 and 1.42, making it the densest wood in the United
States.
• The world's most dense wood is black ironwood (Olea
laurifolia), also called South African ironwood. Found in
the West Indies, it has a specific gravity of 1.49 and
weighs up to 93 pounds (42.18 kilograms) per foot. The
lightest wood is Aeschynomene hispida, found in Cuba,
with a specific gravity of 0.044 and a weight of 2.5
pounds (1.13 kilograms) per foot.
Density of Dead Sea Water =
1.24 Kilograms per Liter!
• In addition to its being the lowest place on
earth, 423 meters (1388 feet) below sea
level, there are many other interesting facts
and figures about the Dead Sea region,
which has been important to mankind from
ancient times until the modern day.
• The Dead Sea is the second saltiest body of
water in the world after Lake Assal in
Djibouti, Africa.
• The salt concentration in the Dead Sea is
33.7%, compared with the salt concentration
in the Mediterranean Sea, which is between
3.5% and 3.9%.
• The high salt content is what makes possible
the unique floating experience enjoyed by
bathers in the Dead Sea.
