Transcript In your notebooks, explain why scientists use scientific notation.

Aim: How is Scientific notation used?
Do Now:
- In your notebooks, explain why scientists
use scientific notation.
Scientific notation is used to write numbers in a
short-hand form. This technique makes really
large or really small numbers easier to read and
write.
Ex:
9,600,000 =
0.00049 =
Rules for writing in Scientific Notation
Step 1: Position the decimal point to get a number
between 1 and 10.
If there is no decimal where does it belong?
Step 2 Count the number of places the decimal
point was moved to get the number between 1
and 10. Where did it start originally?
Step 3 Write the number as a product between 1
and 10 to a power of 10 using the number of
spaces the decimal moved as your exponent.
Closure:
- Take a “Writing numbers in
Scientific Notation” worksheet
from the back.
Working with the person sitting
next to you, work on the
practice problems on the front
of the worksheet.
