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 pointsUnit = meter (m) Instrument = ruler, meter stick, measuring tape A B longer distance C D shorter distance
Time- the measure of the interval between two eventsUnit = seconds (sec) Instrument- watch, stopwatch
Mass- the measure of the amount of material in an objectUnit = gram (g) Instrument- balance less mass more mass more mass less mass
Volume- the amount of space an object occupiesUnit = 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 volumeUnit = 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 substanceUnit = 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 objectUnit = 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
Making Measurements in Science
The Metric System The scientific system of measurement
SI (metric) Measurements
Measurement Measurement SI Standard System of International Units or Metric System Uses 10 as a base Always estimate one unit/place further than.
When we measure you need to know: › What you are measuring (the object) › What you are measuring with (which tool) › What you are measuring in (the.
The Metric System. 1.The Metric System a. Standard system used by scientists. b. AKA S.I. (International System of Units) c. Decimal System based on the.
Reason 1: helps scientists share and compare their data/ results
MEASURING INSTRUMENT S
Tools for Measuring some Physical Properties of Matter Fill in your vocabulary map with the following information!
Qualitative Observations What are the 5 senses?. Write 3 qualitative observations about the following picture...
Scientific experiments often involve making measurements We use the metric system in science! We measure length, weight and mass, area and volume, density,
Length – the distance between 2 points Circumference – distance around a circular object.
Measurement. Create chart on your paper with these headings:
Definition: How long Equipment: meter stick or ruler Units: meters (m) Hint: start at zero on the ruler.
Measurement Basics Physical Science. Why is it important to make accurate and precise measurements? Accuracy is the correctness of a measurement. If your.
Metric Review. International System of Units (SI) Base of 10 1 meter = 100 centimeters=1000 millimeters Standard Units: -Mass = gram (g) -Length = meter.
Standard measure of a quantity Examples › Length = Meter (m) › Volume = Liter (L) › Mass = Grams (g) › Temperature = Celcius (°C)
