    1. 1. Tools Used For Measurement
    2. 2. Units and Tools of MeasurementType of Measurement Unit/ Abbreviation Tool UsedLength Meter, m Meter Stick, measuring tapeMass Kilogram, kg Electronic scale or balanceVolume Liter, l Graduated CylinderTime Seconds, s Stopwatch or clockTemperature Celsius ° C, Kelvin °K Thermometer
    3. 3. Length• Measurement of distance• How long or how far something is• Can measure with a meter stick, measuring tape• SI Unit is the Meter
    4. 4. Length ComparisonSI Unit of Measurement Used Here Centimeters Compliments of Slideshare Kermis June 5, 2008
    5. 5. Mass• The amount of material in an object• Can measure on a scale or balance• SI unit is the Kilogram• Electronic balances can detect measurements to the nearest hundredths or thousandths place

    7. 7. Volume• The amount of space an object or material takes up• Can used a graduated cylinder, syringe, buret, pipet, or volumetric flask• SI Unit is the Liter• Volume= L X W X H• Volume can also be determined by Compliments of Slideshare Kermis June 5, 2008 displacement of water
    8. 8. Volume- MeniscusMeniscus is the curvature ofthe liquid in the containerNeed to get eyelevel withliquid and read the lowpoint of the meniscus asseen hereThis can be a source of errorif not read properly
    9. 9. Time• Units of the day• How long or short something takes; events in the past, present and future• Measured with a stop watch or clock• SI Unit is seconds• Often need to consider significant figures- fractions of a second
    10. 10. Temperature• How hot or cold a material is; the average kinetic energy of a material• SI Unit- Celsius, Kelvin• Tool used- thermometer
