2. Bellwork:
1. Get out your Science Fair topic and write your name in it so it is ready to pass in.
2. Get out your Journal entry so it is ready to check off.
3. Write the objectives on the bottom of your journal entry
4. On a scale of 1 to 5, how confident are you with using the Metric System?

3. The Metric System Take out a sheet of paper and pen or pencil.
Title your paper “Metric System Notes”
Copy only the portion of the powerpoint that is written in red.

4. What is the Metric System?
The metric system is a system of measurement which was developed over many years, and traces its origin to a 1585 book entitled "The Tenth", by Simon Stevin, who suggested that a decimal system be used for weights and measures.

5. The Metric System
Metric System is a common language of measurement in science used all over the world.

6. The Metric System
The metric system is the preferred system of weights and measures for United States trade and commerce, and many business and technology companies in the USA use the metric system, and many products specify both .
But most people have decided that the inconvenience of switching outweighs the benefits.

7. The Metric System Map of Nations that don't use The Metric System
All countries colored in red choose not to use the metric system as their system of weights and measurements.
Myanmar (Burma)
Liberia
The United States

8. The Metric System The Metric System is … - based on 10
- based on only three units of measure: the meter, liter, and gram

9. Comparing Units English Standard vs. Metric system
T. Trimpe

10. English vs. Metric Units: Length
Which is longer?
A. 1 mile or 1 kilometer
B. 1 yard or 1 meter
C. 1 inch or 1 centimeter
1.6 kilometers
1 mile
1 yard = meters
1 inch = 2.54 centimeters

11. English vs. Metric Units: Weight
1 pound = grams
Which is larger?
1. 1 Pound or 100 Grams
2. 1 Kilogram or 1 Pound
3. 1 Ounce or 1000 Milligrams
100 kilogram = 220 pounds
1 ounce of gold = 28,349.5 milligrams

12. English vs. Metric Units: Volume
Which is larger?
A. 1 liter or 1 gallon
B. 1 liter or 1 quart
C. 1 milliliter or 1 fluid ounce
1 fl oz = ml
1 12-oz can of soda would equal approximately 355 ml.
1 gallon = 3.79 liters
It would take approximately 3 ¾ 1-liter bottles to equal a gallon.
1 quart = liters

13. The Metric System
Meter (m) – measures distance (instead of inch, foot, yard, or mile)
Liter (L) – measures volume of liquids (instead of ounce, cup, pint, quart, & gallon) Volume measures how much space something takes up
Gram (g)- measures mass/weight (instead of ounces, pounds, and tons) Measures how heavy something is.

14. The Metric System
Prefixes are added onto a base unit to make it bigger or smaller
Milli- smaller by a 1000
Centi- smaller by a 100
Kilo- bigger by 1000
The Prefixes are the same for liters, grams, and meters.
Millimeter-smaller than a meter by a 1000
Milligram- smaller than a gram by a 1000
Milliliter- smaller than a liter by a 1000

15. The Metric System is based on 10!
KILO 1000 Units
HECTO 100 Units
DEKA 10 Units
DECI 0.1 Unit
CENTI 0.01 Unit
MILLI Unit
Meters Liters Grams

16. Abbreviating the metric system units
Metric base units are abbreviated with one letter:
g for Gram
m for Meter
L for Liter
Metric prefixes are abbreviated with one letter:
m for milli
c for centi
k for kilo
For example, Kilogram: k for kilo + g for gram = kg
Try Millimeter:
Try Liter:

Metric Tools!!!

18. Measuring Length– We use a meter stick
1 centimeter = 10 millimeters
How many millimeters are in 1 centimeter?
What is the length of the line in centimeters? _______cm
What is the length of the line in millimeters? _______mm
What is the length of the line to the nearest centimeter? ________cm
HINT: Round to the nearest centimeter – no decimals.
Ruler:

19. Measuring Mass- We use a digital scale or balance
Find the mass by weighing the object on the digital scale.
Or, find the mass by using the balance.

20. Using a balance Place the object in one tray.
Add the heaviest weight in the other. If it tips, add the next heaviest weight.
Continue adding weights until the scale balances.
Add all the weights up. The total is the weight of the object.

21. Measuring Volume- units are mL
We use graduated cylinders to find the volume of liquids and other objects.
Measure from the bottom of the meniscus (the curve). When using a real cylinder, make sure you are eye-level with the meniscus
What is the volume of water in the cylinder? _____mL
What causes the meniscus?
A concave meniscus occurs when the molecules of the liquid attract those of the container. The glass attracts the water on the sides.

22. Measuring Liquid Volume
What is the volume of water in each cylinder?
Images created at A B C
Pay attention to the scales for each cylinder.

23. Measuring Solid Volume- Units are cm3
We measure the volume of regular object using the formula length x width x height using a ruler.
_____ X _____ X _____ = _____
We measure the volume of irregular object using water displacement, using a graduated cylinder.
Amount of H2O with object = ______ About of H2O without object = ______ Difference = Volume = ______

24. Metric Conversions Ladder Method
T. Trimpe

25. How many jumps does it take?
Ladder Method 1 2 3
KILO 1000 Units
HECTO 100 Units
DEKA 10 Units
DECI 0.1 Unit
Meters Liters Grams
CENTI 0.01 Unit
MILLI Unit
How do you use the “ladder” method?
1st – Determine your starting and ending point.
2nd – Count the “jumps” to your ending point.
3rd – Move the decimal the same number of jumps in the same direction.
4 km = _________ m
Starting Point
Ending Point
How many jumps does it take? 4. 1
__. 2
__. 3
__.
= 4000 m

26. Conversion Practice Try these conversions using the ladder method.
1000 mg = _______ g 1 L = _______ mL 160 cm = _______ mm
14 km = _______ m 109 g = _______ kg 250 m = _______ km
Compare using <, >, or =.
56 cm m 7 g mg

27. Interesting fact about the Metric system
1 mL of water weighs 1 gram. The Formula for Density is Mass Volume

28. The Metric System
The US Congress amended the Metric Conversion Act of and designated the metric system as the preferred system of weights and measures for United States trade and commerce.
