2.  What are you expected to be doing when the bell rings?  When is an acceptable time to use the bathroom?  What happens if I am late to class?  When is make up work due?  What must be worn to participate in lab?  Sign Pride Pact  Turn in Bubble Lab

3.  Today I will be able to: ◦ Analyze the relevance of scientific notation by completing an activity. ◦ Calculate multiplication and division problems using scientific notation.

4.  Small Group Discussion  Small Group Scientific Notation Activity  Scientific Notation Notes  Scientific Notation Practice  Scientific Notation Exit ticket

5.  Signed Syllabus  Scientific Notation Practice  Study for Lab Equipment Quiz

7.  What is scientific notation?

8.  So what?

9.  In groups, brainstorm 3 examples of things that scientists/ engineers could study that would be large enough or small enough for scientific notation to be used to describe them

10.  Each group has an envelope containing numbers in scientific notation and standard notation.  Put the numbers in order from smallest to largest on your desk.

11.  A way to write numbers that are too big or too small to conveniently write in decimal notation  Standard scientific notation format ◦ 6.02 x 10 23  Notice there is only one number before the decimal

12.  Standard Notation – numbers that are in decimal form  When given a number in standard notation move the decimal to the left or right until there is only one number before the decimal  The number of spaces moved to the left or right becomes the exponent  The sign on the exponent is ◦ Positive – moved the decimal to the left ◦ Negative – moved the decimal to the right

13.  Examples ◦ 489000000 (Standard Notation)  Move the decimal to the left, exponent is positive ◦ 4.89 x 10 8 (Scientific Notation) ◦ 0.000123 (Standard Notation)  Move the decimal to the right, exponent is negative ◦ 1.23 x 10 4 (Scientific Notation)

14.  Start with number in scientific notation  Look at the sign on the exponent ◦ If positive, move the decimal to the right ◦ If negative, move the decimal to the left  Use the exponent to tell you how many places to the move the decimal point

15.  Examples ◦ 3.47 x 10 5 (Scientific Notation)  Exponent is positive, move to the right ◦ 347000 (Standard Notation) ◦ 7.82 x 10 -4 (Scientific Notation)  Exponent is negative, move to the left ◦ 0.000782 (Standard Notation)

16.  Multiply or divide the numbers first ◦ (don’t include x 10 exp )  When multiplying, add the exponents together  When dividing, subtract the exponents  Make sure there is only one number before the decimal place in scientific notation. You may have to move the decimal so there is only one

17.  Examples  (2.0 x 10 5 )(7.0 x10 4 )= ◦ 1.40 x 10 10  (6.0 x 10 7 ) / (3.0 x 10 9 )= ◦ 2.0 x 10 -2

18.  Find your matching partner with the same number in Standard form or Scientific Notation!
