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 = =
Rules for writing in Scientific Notation Step 1: Position the decimal point to get a number between 1 and 10. 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. If there is no decimal where does it belong?
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.
