1. The Metric Measurement

2. When and why was the metric system invented?
The metric system was invented in 1790 by French scientists.The metric system was invented because countries were using many different systems of measurement causing confusion and lack of consistency

4. Scientists all over the world use the International System of Units to measure:
Length
Volume
Mass
Temperature
Time

5. The metric system is based on the number 10
The metric system is based on the number 10. Our money system is also a base 10 system
Ex. It takes 10 pennies to equal 1 dime.
A dime is 10x more than a penny. If a dime is = 1 than a penny is 0.1.

6. What is length?
Length is the distance from one point to another

7. Meter
The entire stick is 1 meter.

(King Henry Died Unfortunately Drinking Chocolate Milk)
The three units that measure the length of objects smaller than a meter are, …
decimeter
centimeter
millimeter

9. Smaller than the standard
Deci = 1/10 or .1
Contains 10 decimeter markings.
Every 10th centimeter is denoted as a decimeter by it's bigger font.

10. Smaller than the standard
Centi = 1/100 or .01
Contains 100 centimeter markings.
Numbered markings 1to the end of stick (100)

11. The longer lines on the metric ruler are called…
centimeters

12. Smaller than the standard
Milli = 1/1000 or .001
Contains 1000 millimeter markings (smallest lines)on the stick.

13. The smallest lines on the metric ruler are called…
millimeters

14.  Reading Checkpoint One centimeter is divided into how many millimeters?
10 millimeters (mm)

15. Calculating: Measure the turtle from the rear of its shell to the tip of its nose. Record its length in both centimeters and millimeters.

18. Calculating - How much larger is a kilo- than a deka-?
100 times

19. Volume
The amount of space an object takes up

20. Liter
The bottle is 1 liter (L).
About equal to
1 US quart.

21. To measure the volume of smaller liquids, the _________ is used.
Milliliter (mL)

22. The instrument used to measure the volume of liquids is called the…
Graduated cylinder.

23. This instrument has markings that are in increments of…
1 milliliter (mL)

24. Meniscus
The curve in the top surface of water in the graduated cylinder

25. Figure 4: Observing - What is the proper way to read a meniscus?
Read the milliliter marking at the bottom of the curve
The meniscus is also known as
“the bubble.”

26. Common Conversions For Volume=
1,000 mL
1 mL
1 cm³

27. How can the volume of a solid object such as a shoebox be measured?
To measure a solid objects that are regular shaped, a formula for volume can be applied
To measure a rectangular object such as a shoebox, multiply the object’s length, width, and height

28. The formula for calculating the volume of a rectangular object is:
Volume = Length x Width x Height

29. Why is the unit cm³ used when calculating the volume of a rectangular object?
When multiplying the object’s length, width and height, the cm units are also multiplied
cm x cm x cm = cm³

30. Volume = Length x Width x Height
Suppose a cereal box is 10 centimeters long, 4 centimeters wide, and 20 centimeters high. What would be the volume of the box?
Volume = Length x Width x Height
Volume = 10 cm x 4 cm x 20 cm
Volume = 800 cm³

31. How is the volume of an irregular solid such as a rock measured?
To measure the volume of an irregular solid, immerse the object in water, and measure how much the water level rises
Water displacement method

32. How does the water displacement method work?
Record the volume of water in the graduated cylinder.
Carefully place the irregular solid into the water. Record the volume of the water plus the object.
Subtract the volume of the water alone from the volume of the water plus the object.

33. Mass The measure of the amount of matter an object contains.
Matter: The material that all objects and substances are made up of
Anything that has mass and takes up space is matter

34. Mass is measured with an electronic balance.

35. Figure 3: Observing - What is the mass of this turtle?
153.7 grams

36. Gram The gold square is 1 gram. About equal to the mass
of a large paper clip.

37. Bigger than the standard
Deka = 10
If you had 10 of the gold squares you would have a dekagram of gold.

38. Bigger than the standard
Hecto = 100
If you had 100 of the gold squares you would have a hectogram of gold.

39. Bigger than the standard
Kilo = 1,000
If you had 1,000 of the gold squares you would have a kilogram of gold.

40. KHDUDCM (King Henry Died Unfortunately Drinking Chocolate Milk)
The three units that measure the mass of objects larger than a gram are, … Dekagram Hectogram Kilogram

42. Recap
There are ________ grams in a dekagram; there are ________grams in a hectogram; there are _______ grams in a kilogram.
1/26/14

43. Reading Metric Units mg = milligram
m is for the prefix milli and g is the standard for gram
dkL = dekaLiter
dk is for the prefix deka and L is the standard for liter
g = gram
Gram is the standard for mass.

44. Temperature- Celsius & Kelvin
Take Celsius and add 273 to get Kelvin.
The Kelvin scale measures
absolute zero.
