#### Transcript of Basic Scientific Measurements

o Lesson Objectives Basic Scientific Measurements Mass in an object Time SI unit for time is second (s) Temperature cannot be changed by its location amount of matter SI unit for mass is kilogram (kg) Other units are gram, milligram, tonne 1 kg = 1000g
1 g = 1000 mg
1 tonne = 1000 kg To measure mass, we use a 2. Electronic balance 1. Beam balance Mass are suitable to measure mass. They are used to measure weight. balance Spring balances not Other units are hour (h), minutes (min) 1 h = 60 min
1 min = 60 s Time To measure time, we can use stopwatch 1. Mechanical stopwatch 2. Electronic stopwatch SI unit is Kelvin (K) Other units are Degree Celcius ( C), Fahrenheit (F) 1. Laboratory Thermometer 2. Digital Thermometer 3. Data Logger http://powersof10.com/film Prefixes are added to basic units to give larger or smaller units.
