Scientific Method
What is Science?
The study or explanation of phenomenon
10.73 ms = _____ s
10,730 s
What is the formula for Volume?
V = l*w*h
Volume = length x width x heaight
What is a prefix?
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit.
What is a Hypothesis
An educated guess containing usually containing an "if, then" statement.
Convert 86.88g = ______ kg
.08688 kg
What is the formula for Density?
D= M/V
Density = Mass divided by Volume
What prefix means a 1000?
Kilo
What is an independent variable?
It is a variable that stands alone and isn't changed by the other variables you are trying to measure.
18 hm = ____ m
1800 m
An object has a Mass of 30 g. And a length of 10 cm, a width of 5 cm, and a height of 8 cm.
What is the Density of the object?
(Show/Explain steps)
1. V= 10 x 5 x 8
= 400 cm^3
2. D= 30g/400cm^3
= 0.075 g/cm^3
What is a base unit? Which 4 did we discuss?
one of a set of fundamental units in a system of measurement that is based on a natural phenomenon or established standard and from which other units may be derived.
g , L , m , s

What is a dependent variable?
The dependent variable is the variable being tested and measured in an experiment, and is 'dependent' on the independent variable.
103.7 cm^3 = _____ L
.1037 L
An object has a Density of 12 g/cm^3 and a Mass of 96 g.
What is the Volume?
12 = 96/V
12V=96
V= 8 cm^3
What prefix means a million? What is it represented by?
Giga
