  28. Metric Measurement Measuring with the Metric System

  29. Measuring Temperature Temperature - the measure of how hot or cold something is Instrument - thermometer Metric unit of measurement - degrees Celsius 0 C

  30. Comparing Temperature Scales

  31. Celsius scale Fahrenheit scale U. S. standard system commonly used by scientists 0 F water boils at 1000 C water freezes at 00 C Units of Temperature Kelvin scale official SI unit 0 K coldest temperature – absolute 0

  32. Reading a Thermometer http://www.echalk.co.uk/maths/dfes_numeracy/Assets/thermometer_flash.swf http://www.mathsisfun.com/measure/thermometer.html

  33. Measuring Mass Mass : the measure of the amount of matter in an object Metric unit of measurement: gram g Instrument used: triple-beam balance

  34. Balances are used to measure mass. Scales are used to measure weight. Different weights

  35. Measuring Mass Characteristics measured in g and kg; measured with a balance Definition the measure of the amount of matter in an object Mass Examples paper clip = 1 g baseball bat = 1 kg 1 kg = 1 000 g Nonexamples weight-a force measured with a scale

  36. Triple-Beam Balance triple beam balance triple-beam balance measuring mass with a triple beam balance

  37. Measuring Length Length: the distance between two points Metric unit of measurement: meter m Instrument used: metric ruler meter stick

  38. Definition – the distance between two points Length Units of Length Measuring Length basic unit - meter metric ruler meter stick smaller measurements: cm, mm larger measurement: km divided into cm and mm 1 cm = 10 mm

  39. You are 1.8 m tall, so that makes you 180 cm or 1 800 mm tall.

  40. Using a Metric Ruler What’s my Length?

  41. The metric unit of measurement for length is the meter. Length – the distance between two points

  42. Measuring Volume Definition: The amount of space an object occupies

  43. Measuring Volume of Liquids Metric unit of measurement: liter L Instruments used: graduated cylinder beaker

  44. Measuring Volume: Outline I. Volume a. Definition: the amount of space an object takes up (or occupies) • Volume of Liquids • a. Equipment Used: • b. Unit of Measurement: graduated cylinder, beaker liter (L) milliliter (mL)
