INTRODUCTION
Science and Math go
hand-in-hand. For example,
mathematical formulas are
used in daily scientific
tasks. A formula is used
when you have to find
whether or not a block of
wood would float during a
science lab, volume of a
penny with a graduated
cylinder, number of protons
and neutrons in a Neon
atom, and to find the ionic
charge for ionic bonding.
DENSITY
Density:
the ratio of the
mass of a
substance to
the volume of
the
substsance
 Let D= density
 Let V= Volume
 Let M= Mass

DENSITY FORMULA
The Density Formula is
D=M/V in which to find the
density, you must divide
the mass of the wood by
volume of the wood. The
label is grams per cubic
centimeter.
D=M/V
M=60 grams
V= 120
centimeters
cubed
D=60 grams/
120 centimeters
cubed
D=0.5 grams per
cubic centimeter
This block of
wood would float
because it has a
density less than
water’s which is 1
gram per cubic
cm.
BLOCK OF WOOD
DENSITY CONTINUED
Without division no one would be
able to decipher the density of a block
of wood. You would not be able to
determine whether the block of wood
would float or sink.
VOLUME





Volume is the
measure of the size
of a body or region in
three-dimensional
space
It is also used in the
density formula
Let V=Volume
Let w= water
measurement
Let r=measurement
of water with the
penny
PENNY
Rock:
V=r-w
w=50 grams
r=75 grams
V=75-50 grams
V=25 centimeters cubed
VOLUME IN
LIFE
•
Volume is used to find the
density of an object and without
subtraction it would be
impossible
PROTONS AND NEUTRONS



Protons are positively
charged particles in
the nucleus of an
atom
Neutrons are
neutrally charged
particles in the
nucleus of an atom
The number of
protons is shown on
the periodic table
above the element
symbol

The atomic mass is protons
and neutrons combined and
found underneath the
element’s name.
HOW MANY PROTONS AND NEUTRONS




Let p=number of
protons
Let n=number of
neutrons
Let a=atomic mass
The formula is “n=a-p
Example: n=a-p
p= 10
a=20
n=20-10
n=10 so there are 10
neutrons
MATH AND PROTONS AND NEUTRONS

You could
never find out
the number of
protons and
neutrons of
neon without
subtraction
THE IONIC CHARGE




To find the ionic charge of
Silicon you have to use
subtraction. If math did
not exist, no one would be
able to find out the ionic
charge of Silicon for ionic
bonding. (image of ionic
bond to the right.)
Let i= the ionic charge of
silicon
Let p=number of protons
in Silicon
Let e=number of
electrons in Silicon


SILICON
i=p-e
The formula is “i=pp=14
e”
e=18
The number of
i=14-18
protons is
subtracted by the i=-4
number of
The ionic charge of Silicon is -4
electrons
IONIC CHARGE FORMULA
FORMULA
CONCLUSION
Math moves Science.
Without math, you would not
be able to perform labs,
make a Bohr or Lewis
Structure of protons and
neutrons, decide whether an
object would sink or float,
determine the ionic charge
of Silicon for ionic bonding,
or finding the volume of a
substance. Participating in
Science would be impossible
without the assistance of
Math.
