First of all, what is scientific notation

First of all, what is scientific notation?

• Scientific Notation is an easier way of writing
  very large or very small numbers. A number
  expressed in scientific notation is expressed as
  a decimal number between 1 and 10 multiplied by a
  power of 10 . (example is 1.122 x 10-5)

Scientific Notation The Donkey and the Zebra

• One day, a donkey found a zebra.I bet I am
  smarter than you in math! Said the donkey.
  Okay, we can do a project on scientific
  notation. Whoever can do the better project is
  the smarter animal said the zebra. Well, Im
  going to start now! Said the donkey.

Scientific Notation The Donkey and the Zebra

• This has been a big thing between the zebra
  and donkey.They hired judges to see who would
  have the better project.First, we will see what
  the donkey is working on.

Scientific Notation The Donkey and the Zebra

• The Donkey has a button that is 1 millimeter in
  diameter and he wants to find out how many
  kilometers that are in the millimeter. Then,
  thats when he will use scientific notation to
  finish his project. Using rulers, papers, and
  calculators, the donkey finds out that there are
  0.0000001 kilometers in a millimeter.

Scientific Notation The Donkey and the Zebra

• Now its time to find the scientific notation.
  1.0 10-6 - thats the scientific notation, but
  I should tell you how I found it. First, I took
  the number 1.0, then I moved the decimal point 6
  places over to the left. The reason why I moved
  it to the left is because I need a number that is
  less than 10 and greater than 0. Our new number
  is 0.0000001 . We moved it over 6 places, so our
  new exponent will have to be 6.

Scientific Notation The Donkey and the Zebra

• That was the end of the donkeys project. Lets
  take a look at the zebras project. He did it on
  a human in nanometers.

Scientific Notation The Donkey and the Zebra

• This is going to be an extremely large number.
  The person that we are measuring is 5 feet.There
  are 25,400,000 nanometers in only 1 inch! Thats
  going to be a lot of nanometers for someone who
  is 5 feet! Lets do the math. 60 x 25,400,000
  1,524,000,000.There are 1,524,000,000 nanometers
  in 5 feet. Now all we have to do is convert it
  into scientific notation. We first need to make
  it a number less than 10 but greater than 0. Move
  it over 9 times and you should get 1.524 . Always
  remember that the exponent is always the number
  of times we moved the decimal point. The
  scientific notation should be 1.524 x 109 .

The Winner!

• Its time to find the winner!The judges score
  the donkey 10/10zebra 10/10They both tied!
  Well, I guess we are both smart in math said
  the donkey. I guess so! said the zebra. But,
  said the donkey. But what? said the zebra. I
  surely am smarter than you in science! said the
  donkey Its on then! said the zebra.
