1 Measurements! 1

2 Background on SI Units Scientists use the metric system which is the international system (SI) of measurement. France was the 1 st country to adopt the metric system in

3 Standardization SI units were designed to provide a worldwide standard of physical measurement for science, industry, and commerce. SI was adopted worldwide in

4 MASS 1. Definition: * Mass is the amount of matter in an object. 2. Base Unit: * gram (g) * larger masses = kilogram (kg) * smaller masses = milligram (mg) 4

5 MASS 3. Instrument:

6 REMINDER about MASS Weight is a measurement of force, and will change depending on gravity. The weight of an object can change but the mass remains the same. 6

7 VOLUME 1. Definition: * Volume is the amount of space an object takes up 2. Base Unit: * liquid volume = liter (L) * solid volume = cubic meter (m 3 )

8 LIQUID VOLUME 3. Instrument: * Liquid Volume - beaker, graduated cylinder, or a flask

9 SOLID VOLUME 3. Instrument: * Solid volume - metric ruler using the formula: L x W x H = V 3cm x 2cm x 4cm = 24cm 3

10 LENGTH 1. Definition: * Length is a measure of distance 2. Base Unit: * meter (m) * longer lengths = kilometers (km) * shorter lengths = centimeters (cm) 3. Instrument: * metric ruler * for very large distances: light year

11 TEMPERATURE 1. Definition: * Temperature is the measurement of the amount of heat in an object 2. Base Unit: * Celsius ( ⁰ C) * very hot or very cold temperatures = degrees Kelvin (K) 3. Instrument: * thermometer
