# McCormack-Metric Sys

### McCormack-Scientific Method & Metric System

TermDefinition
Density Density = Mass/Volume
Meter The Metric base unit for measuring length.
Gram The Metric base unit for measuring mass.
Volume The Metric measurement for the amount of space an object takes up.
Independent Variable The variable in an experiment that the scientist controls.
Dependent Variable The variable that changes with the Independent variable.
Controls Experimental states that stay the same throughout the experiment.
Celsius is Metric Unit for measuring temperature
Triple Beam Scale Instrument for measuring mass, grams
Graduated Cylinder Instrument for measuring volume, mL
Liter, meter, gram Base metric units of measure
Kilo = Prefix for 1,000 (1 x 10^3)
Mega = Prefix for 1,000,000 (1 x 10^6)
Giga = Prefix for 1,000,000,000 (1 x 10^9)
Tera = Prefix for 1,000,000,000,000 (1 x 10^12)
milli = Prefix for 1/1,000
The number of millimeters in a meter is 1,000
The number of centigrams in a gram is 100
The number of deciliters in a liter is 10
centi = Prefix for 1/100
Density is the relationship between mass & volume
Density formula is D =mass/volume (D=m/v)
The density of pure water is 1.0 g/mL
As mass increases, Density will ___________ Increase (directly related)
As volume increases, Density will___________ Decrease (indirectly related)
Oil floats on water, its density must be __________ less than 1.0 g/ml
Karo syrup will sink below water, its density must be______ greater than 1.0 g/ml
In a hot air balloon, as air heats up it expands, Volume will _______ and Density will ____________, the balloon will rise. Volume will increase and Density will decrease, the balloon will rise.
Hot water is ____________ dense than cold and will _________ less dense than cold and will float
Ice has a density of .971 and floats because it Has a crystal structure and air pockets.
Cold water is _________ than hot water and will _______ Denser , sink
