1 Biology 9/11/13 Mrs. Turgeon “Success consists of going from failure to failure without loss of enthusiasm.” – Winston Churchill DO NOW: Get out your 3-ring Biology binder and wait quietly for instructions

2 4 Respond to the following in your notes 1. What units do you use to measure: a.) length? b.) mass? c.) volume? 4 Copy the text in your notes 3 times: 4 Kilo-hecta-deka-base unit-deci-centi-milli 4  You will need to memorize this! It will help you in all future science classes!

3 What are Metric Conversions? 4 Sometimes we need to change from one measurement to another. 4 This is usually done because the unit that is used is either too big or too small for that type of measurement.

4 TOO BIG !!! 525,568 millimeters Sometimes the number is too big for the unit being measured.

5 Too Small 0.00654 km Sometimes the number is too small for the unit being measured

6 How Do We Fix This Problem? We can correct these problems by doing a process called Metric Conversion. Metric Conversion: changing from one unit of measurement to another.

7 Biology 9/13/13 Mrs. Turgeon “All the great things are simple, and many can be expressed in a single word: freedom, justice, honor, duty, mercy, hope.” – Winston Churchill DO NOW: Put everything away except for your pencil and be ready for Our first ACT practice test! ( woo-hoo! This is fun! ) Announcement: Our first Science Club meeting is in room 312 (Here) on Tuesday, Sept. 17 at 4:00. Put this date in your agenda book if you would like to join!

8 Biology 9/13/13 Mrs. Turgeon 4 Agenda 1. ACT practice quiz 2. Finish Volume Lab 3. Practice with the metric system

9 Staircase Method (copy this) Kilo- Hecto- Deka- base units Deci- Centi- Milli- Base units g, m, L  Larger units Smaller units  Move up the stairs, decimal moves to the  Move down the stairs, decimal moves to the 

10 Using the stair step method 1. Find your starting step 2. Count the # of steps it takes to get to the step that you need to stop on. A. If you move to the  (downstairs) the decimal in the first measurement moves that many places to the . B. If you move to the  (upstairs) then the decimal moves to the . 3. Fill any empty places with zeros.

11 The Stair-step Kilo- Hecto- Deka- base units Deci- Centi- Milli- Grams, liters,meters

12 525568 mm = ? m Millimeters are a very small amount of distance. You would not want to measure a large distance in a very small unit. Kilo- Hecto- Deka- base units Deci- Centi- Milli- Base units g, L,m Moved 3 to the  525.568m

13 0.00654 km = ? m Kilometers(km) are a fairly large unit of distance. You would not want to measure a small distance in a large unit, so we need to convert it to a smaller unit, the meter. Kilo  m is 3 steps to the right Therefore, 0.00654 km becomes 6.54 m.
