  1. Visualizing the Metric System

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

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

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

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

  6. A unit that measures the length of larger objects is…. • kilometers

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

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

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

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

  20. Length Reading a metric ruler…..

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

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

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

  24. 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

  25. Volume

  26. Volume • The amount of space an object takes up

  27. Volume Volume of Liquids

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

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

  30. Larger liquids are measured in kiloliters.

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

  32. 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 =

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

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

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

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

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

  38. 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

  39. 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

  40. Mass

  41. 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

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

  43. Mass Units of Mass

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

  45. A smaller object’s mass such as a paper clip would be measured inmilligrams.

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