2. Visualizing the Metric System By Mrs. Kell / Elmwood Academic Facilitator

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

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

5. The basic unit of length in the metric system is the meter.

6. The two units that measure the length of smaller objects are, … millimeter centimeter

7. A unit that measures the length of larger objects are…. kilometers

8. A meter is about the height from the floor to the knob on a door.

9. A centimeter is about the width of your fingernail. A millimeter is about the thickness of a dime.

10. 1 kilometer is about the combined length of 9 football fields.

11. Question: About how many centimeters is the width of your paper?

21. Length Reading a metric ruler…..

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

23. The shorter lines on the metric ruler are called… millimeters

24. One centimeter is divided into how many millimeters? 10 millimeters (mm)

25. Calculating: Measure the turtle in figure 2 from the rear of its shell to the tip of its nose. Record its length in both centimeters and millimeters. 10.5 cm 105 mm

26. Volume

27. The amount of space an object takes up

28. Volume Volume of Liquids

29. When measuring the volume of a liquid, scientists use a unit known as the… Liter (L).

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

31. Larger liquids are measured in kiloliters.

32. A liter is the size of a coke bottle.

33. 1 milliliter equals 1/1000 of a liter… In other words it would take about 1,000 die to fill up a liter bottle…. 1,000 of these =

34. A kiloliter is equivalent to 8 large trash cans.

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

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

37. Common Conversions For Volume 1 L= =1,000 cm³ 1 mL=

38. Common Conversions For Volume 1 L=1,000 mL =1,000 cm³ 1 mL=

39. Common Conversions For Volume 1 L=1,000 mL 1 L=1,000 cm³ 1 mL=

40. Common Conversions For Volume 1 L=1,000 mL 1 L=1,000 cm³ 1 mL=1 cm³

41. The metric unit known for measuring solids with a larger volume is known as the… Cubic meter (m³).

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

43. 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

44. 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

45. Mass

46. 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

47. A balance is used to measure mass. Pan Riders Beams Pointer

48. Mass Units of Mass

49. The gram (g) is the basic metric unit of mass. Two other metric units of mass are: milligram (mg) kilogram (kg)

50. A smaller object’s mass such as a paper clip would be measured in milligrams.

51. A gram is about the mass of a jelly bean

52. A kilogram is about the mass of a baseball bat.

53. Conversions 1 kg=g 1 g=mg

54. Conversions 1 kg=1,000g 1 g=mg

55. Conversions 1 kg=1,000g 1 g=1,000mg
