1.  Standard measure of a quantity  Examples › Length = Meter (m) › Volume = Liter (L) › Mass = Grams (g) › Temperature = Celcius (°C)

2.  Measure of the amount of matter in an object  Tools › Scale › Balance  Unit › Kilogram (kg) › Gram (g) › Milligram (mg)

3.  Measure of the amount of matter in an object  Mass of an object is the same no matter where it is located › Does not change with location  Only way to change is to add or take away matter

4.  Measure of the gravitational force (pulling) exerted on an object  Changes when the force of gravity changes › Differs on Earth & Mars  Tools › Spring Scale  Unit › Newton (N)

5.  Measure of the size of a body or region in a 3-D space  Meniscus: curvature of the water’s surface that’s to be measured at the lowest point of the curve  Tools › Beaker › Graduated cylinder

6.  Unit › Cubic Meter (m 3 ) › Cubic Centimeter (cm 3 ) › Milliliter (mL) › Liter (L)

7.  Measure of the size of a surface/region  Tools › Meter stick › Ruler  Unit › Square Meters (m 2 ) › Square Centimeters (cm 2 ) › Square Kilometers (km 2 )

8.  Measure of how hot or cold something is  Measure of the average kinetic energy of the particles in an object  Tools › Thermometer  Unit › Kelvin (K) › Celsius (°C)

9.  Ratio of the mass of a substance to the volume of a substance  Tools › Mass: Balance or Scale › Volume: Graduated Cylinder/Beaker/Ruler  Unit › g/mL › g/cm 3
