  1. Objectives: • Scientific Notation Write this in your journal. What do I know about…scientific notation What do I think is …the reason why we use scientific notation What do I now know… What do I now think is… • Unit 1 – What is Science? • Experimental Data • Presenting Scientific Data

  2. A shortcut used to report numbers that are really small or really large. Makes it easier to enter into calculators and calculate. What is Scientific Notation? 602000000000000000000000 6.02 x 1023

  3. Why Can’t We just leave off the zeros? $25,000.00 $25.00

  4. Let’s Try Which numbers are written in scientific notation? .000057 2.45 x 1045 2.45 x 10-7 1250000000000

  5. How do I put it into scientific notation? 6.02 x 1023

  6. What are the rules? Exponent 6.02 x 1023 • Should always have the decimal after the first non-zero number • Should never include trailing zeros or leading zeros • The exponent is the number of decimal places the decimal moved. Coefficient

  7. What are the rules?

  8. What are the rules?

  9. Let’s Try Which numbers are written in scientific notation? .000057 2.45 x 1045 2.45 x 10-7 1250000000000

  10. Let’s Try Let’s try it on the white boards.

  11. How do I put it into my calculator? (TI30XA) 6.02 6.02 x 1023 EE 23

  12. WOO HOO!!!!! Let’s Try

  13. What if my calculator breaks? (9.45 x 1034) (2.58 x 1042) Multiply Coefficients Add the exponents

  14. Last step – Make sure the answer is in scientific notation

  15. What if my calculator breaks? (9.45 x 1034) /(2.58 x 1042) Subtractthe exponents Divide Coefficients

  16. Last step – Make sure the answer is in scientific notation

  17. Let’s Try WOO HOO!!!!!
