Warm up 8/30/07

  • What did you discover from yesterday’s lab?

  • Find the volume of the object in cm³ and mL

2 cm

5 cm

2 cm


Announcements

Announcements

  • If you were absent be sure to check the grey folder in absent work bin to get stuff missed

  • If you leave anything here, it will be in the work passes back bin

  • If you bring in pennies before 1982 you will receive a no homework pass.

  • 1 penny = 5 pt homework pass


The metric system

The Metric System

In science class, we will be using the METRIC SYSTEM.


Warm up 8 30 07

We use different measurements depending on how big or small and object is-

For example, you would use centimeters to measure a coin, and kilometers to measure the distance from San Marcos to Escondido.

We can change the standard unit using

pre-fixes


Warm up 8 30 07

The prefixes are (from largest to smallest)

  • Kilo- K

  • Hecto- H

  • Deka- D

  • Unit- Meter, Liter or Gram

  • Deci- d

  • Centi- c

  • Milli- m


Pre fixes

We can think of the prefixes like a stair step

Converting

Converting

When you go down the stair to the right, you move the decimal over that many spaces in the same direction.

For example: convert 5.5 Dl to cl

KHDUDCM

5

5

3 spaces moved to the right, so move decimal point 3 to the right

5,500 cl


Let s try another

Let’s try another

Convert .77 cg to kg

77

5 spaces to the left, so move decimal point 5 to the left

.0000077 kg


Your turn

Your turn!

Convert 25 cm to Dm

KHDUDCM

25

3 spaces to the left, so move decimal point 3 to left

ANSWER: .025 Dm


Again your turn

Again, your turn

Convert 12.6 km to dm

KHDUDCM

4 spaces to right = 126,000 dm

Converting SI Units

If you move down the stair step, you move the decimal to the right…

2.6 km = _260,000_ cm

2.6 km = _________ cm

If you move up the stair step, you move the decimal to the left

3,700 mm = ______ m

3,700 mm = __3.7__ m
