Distance
Includes length, width, and height
Basic unit is meter
Meter stick is common tool
Metric System
Common measurement (aka System International ,SI) , based on units of ten.
Mass
The amount of matter in an object
Anything that takes up space and can perceived by one or more senses
Basic unit : Gram
Common Tool: Balance
Time
Basic Unit: second
Common tool: stopwatch
Volume
The amount of liquid an object can hold.
Unit of Measurement: litter
Unit of measurement: cubic centimeter
Common Tool: graduated cylinder or beaker
Volume: L X H X W
Volume for displaced object is water displacement
Formula for water displacement 1.0 mL= 1.0 cubic centimeter.
Temperature
Basic unit: Celsius
Common Tool: thermometer
Boing Point: 100
Freezing point:0
Formula from F-C: (F-32) X 5/9=C
Formula from C-F: (C X 9/5) + 32= F

Density
The ratio of the mass of the object to its volume.
D= mass/volume
Density if water: 1.06 g/mL
Density of the object is lower than water: the object will float
Density of object is higher than water: the object will sink
Density is the same as water: There will be suspension.
Density formulas
D=m/v
V=m/d
M=d X v
Speed
Speed is the overall rate of motion of an object
Speed has no direction
Speed= d/t
Speed formulas
S=d/t
D= s•t
T=d/s
