When you finish identifying the equipment complete the worksheet titled Lab Equipment we will review as a class. What is scientific notation? So what? 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 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. 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 Notice there is only one number before the decimal 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 Examples (Standard Notation) Move the decimal to the left, exponent is positive 4.89 x 10 8 (Scientific Notation) (Standard Notation) Move the decimal to the right, exponent is negative 1.23 x (Scientific Notation) 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 Examples 3.47 x 10 5 (Scientific Notation) Exponent is positive, move to the right (Standard Notation) 7.82 x (Scientific Notation) Exponent is negative, move to the left (Standard Notation) Multiply or divide the numbers first (dont 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 Examples (2.0 x 10 5 )(7.0 x10 4 )= 1.40 x (6.0 x 10 7 ) / (3.0 x 10 9 )= 2.0 x 10 -2 Complete the practice at your desk. We will review selected problems as a class. Find your matching partner with the same number in Standard form or Scientific Notation!
