  1. How many sunflowers are in this field?

  2. How much water do the people of Chicago use daily? 9,100,000,000 liters

  3. 2 000 000 000 000 000 000 000 000 000 000 000g What is the mass of the sun? Earth

  4. 9,100,000,000 liters 2 000 000 000 000 000 000 000 000 000 000 000g So how can we write this in simpler way??

  5. Scientific Notation: • Scientific notation is used to express very large or very small numbers.

  6. Parts of Scientific Notation 2.32 x 107 A number between 1 and 10 x 10 to some power

  7. Determine whether or not the given expression in a Scientific Notation Scientific Notation • 2.32 x 107 _________________ • 1 x 10-8 _________________ • 51.4 x 10-2 _________________ • 7.08 x 119 _________________ Scientific Notation Not a Scientific Notation Not a Scientific Notation

  8. Writing Scientific Notation . 9 100 000 000 Step 1: Place the decimal after the first number 9.1 Step 2: Count the number of places 9.1 x 109
