1.3 Tools & Techniques (Measurement Systems) 10/4/16
Learning Objective: I can describe the various units of measurements that scientists use to make observations, gather, and record data.
Measurements taken by scientists are expressed in the International System of Units (SI; Systeme Internationale), which is the official name of the metric system.
The International System of Units is used by all scientists because they need to share a common measurement system for consistency of data. SI is also preferred by scientists because it is scaled in multiples of 10, which makes the system easy to use.

measurement - a determination of the dimensions of something using a standard unit; example: 5 centimeters, 12 liters, 7 kilograms, 30 seconds.
The most common measurements we use in science are time, mass, length, area, volume, & temperature.
unit - a quantity adopted as a standard of measurement; example: centimeter (cm), liter (L), kilogram (kg), second (sec).
quantity - a specific magnitude, size, or amount expressed in a numerical value; example: 5 cm, 12 L, 7 kg, 30 sec
What is the quantity and unit of the following measurements?
50 mL
4.0 mg
53 cm^2
