What Is Measurement? A record of an observation that cannot be made by the five senses alone Usually made with the use of an instrument

5 Major Types Of Measurement

Length Length: the distance between 2 points Use A Ruler or A Meter Stick

Every measurement has a common unit of measurement that accompanies it

What Are Those Markings?? Millimeters Centimeters

Mass Mass: the amount of matter in a given object We use a BALANCE to measure mass

UNITS Every measurement has a common unit of measurement that accompanies it Grams (g) Mass =

VOLUME 3 Ways to Measure Volume VOLUME: the amount of space an object takes up 3 Ways to Measure Volume If it’s a regular solid, use the mathematical equation: volume = length x width x height 2. If it’s a liquid, use a graduated cylinder 3. If irregular, use the displacement method

cubic centimeters (cm3) More units? Yes, more units… milliliters (mL) Liquid Volume = cubic centimeters (cm3) Solid Volume =

Water Displacement 3 Steps Take an initial volume of the water in the graduated cylinder 2. Place the object in the water 3. Observe the new volume and subtract the initial volume from the new volume

You Try!!! Final Volume = 9.8 mL - Initial Volume = 8.8 mL Volume of Object = 1.0 mL

It’s Getting’ Hot In Herre… Temperature: average kinetic energy of an object We measure this with the usage of a thermometer, but what type of thermometer????

Or Degrees Fahrenheit (oF) Are We There Yet??? YES!! More Units!!!! Degrees (Celcius) Temperature = Or Degrees Fahrenheit (oF)

TIME Measurable period during which something happens timeline clock

Units Seconds Mya (millions of years ago)

Rounding When you measure or calculate a number with a decimal you should round.

What does it mean to round your number to the Nearest tenth = one number past the decimal Nearest hundredth – second place past the decimal Nearest thousandth – third place past the decimal

Nearest Nearest Tenth Thousandth 3.65485 = __________ _________ 10.432458 = ________ ________ 3.7 3.655 10.4 10.432
