I. MEASUREMENTS A. ALL MEASUREMENTS MUST HAVE TWO PARTS 1. A NUMBER
– TELLS HOW MUCH IS BEING MEASURED 2. A UNIT – TELLS WHAT IS BEING MEASURED EX: 1 gram 50 seconds mass time

A. Base Units – a unit based on an object or
event in the physical world. B. Derived units – unit defined from a combination of several base units ex: Density = mass / volume units: g / L

Distance- the measure between two points
Unit = meter (m) Instrument = ruler, meter stick, measuring tape A B longer distance C D shorter distance

Time- the measure of the interval between two events
Unit = seconds (sec) Instrument- watch, stopwatch

Mass- the measure of the amount of material in an object
Unit = gram (g) Instrument- balance less mass more mass more mass less mass

Volume- the amount of space an object occupies
Unit = Liter (L) or cubic centimeters (cm³) or (cc) Instrument- graduated cylinder or ruler Formula: V = l x w x h (cube, rectangular prism)

Density- the measure of the amount of mass in a given volume
Unit = grams or grams (g/L or g/cm³) liter cm³ D = mass volume Instrument- balance and graduated cylinder

Temperature- the amount of energy in the particles of a substance
Unit = degrees Celsius (°C) , Fahrenheit (°F), Kelvin (K) Instrument- thermometer K = 273 -°C °F = °C(1.8)+32 °C = 273+K °C = °F-32 (1.8)

Area- the measure of the surface of an object
Unit = centimeters squared (cm²) Instrument- ruler A = l x w (square, rectangle) A = pr (circle) outside of outside shell balloon of egg

Create a foldable with each of the 6 standards of measurement
