10. Notes: The Metric System Based on powers of 10 So every step up or down the scale is ten times bigger or smaller than the one before it ***exception to the rule: after 10 3 or 10 -3 the exponents start moving by 3’s so they are 1000 times bigger or smaller than the one before it – not 10 times.

11. Notes: The Metric System Let’s try some examples

13. Notes Temperature Scale

14. Kinetic E = Notes: Temperature Scales Temperature is a way to measure the average kinetic energy of the particles in a sample of matter Temperature reading on the thermometer There are 3 scales that we use: 1. Fahrenheit ◦ F 2. Celsius ◦ C 3. Kelvin K - no degree symbol

15. Notes: Temperature Scales

16. ◦ F = 1.8 ◦ C + 32OR ◦ C = ( ◦ F - 32) ÷ 1.8 K = ◦ C + 273OR ◦ C = K - 273 K = [( ◦ F - 32) ÷ 1.8] + 273OR ◦ F = 1.8(K-273) + 32

17. Notes: Temperature Scales Let’s look at 3 examples

18. Notes Scientific Notation

19. Notes: Scientific Notation N x 10 n A number between 1 and 10 (usually a decimal) A whole number (+ or -) + means bigger number - means smaller number Scientific notation is a shorter way to write a really really big, or really really small number. A number written in scientific notation has the same value as the longer number, it’s just written differently. It’s like writing your initials instead of your full name. Your initials still mean your name, they’re just written differently.

20. Notes: Scientific Notation Scientific notation is a shorter way to write a really really big, or really really small number. A number written in scientific notation has the same value as the longer number, it’s just written differently. It’s like writing your initials instead of your full name. Your initials still mean your name, they’re just written differently. 3.45 x 10 9 L is the same as… 3,450,000,000 three billion, four hundred and fifty million Liters OR 3.45 Gigaliters (GL)

21. Notes: Scientific Notation Scientific notation is a shorter way to write a really really big, or really really small number. A number written in scientific notation has the same value as the longer number, it’s just written differently. It’s like writing your initials instead of your full name. Your initials still mean your name, they’re just written differently. 0.000000000009 g is the same as… 9 x 10 -12 grams, OR 9 picograms (pg)

A number written in scientific notation has the same value as the longer number, it’s just written differently. It’s like writing your initials instead of your full name. Your initials still mean your name, they’re just written differently. 6.7 x 10 6 m is the same as… 6,700,000 six million, seven hundred thousand OR 6.7 Megameters (Mm)
