nature. Intended to be universal.
Scientific Investigation: - ANSWER Scientists test their ideas with a variety
of different types of investigations. Ex: laboratories, controlled experiments,
astronomy, field studies, models.
SI System: - ANSWER International System of units based on the metric
system and units derived from the metric system.

(3) Second (s)-time
(4) Kelvin (K)-temperature
(5) Amperes (A)-"amp"-electric current
(6) Candela (cd)-light intensity
(7) Moles (mol)-amount of substance
,Time: - ANSWER Base quantity that measures how long an event lasts or
the break between events.
Length: - ANSWER Used to describe the distance between two objects, or
the two ends of an object.
Mass: - ANSWER Used to describe the amount of matter in an object.
Temperature: - ANSWER A measure of how hot or cold something is.
Gram: - ANSWER a metric unit of mass equal to one thousandth of a
kilogram.
Meter: - ANSWER The base unit of length in the metric system. Unit
symbol (m).
Liter: - ANSWER Basic unit of volume in the metric system. Unit symbol (l).
Second: - ANSWER SI base unit for time. Unit symbol (s).
Kelvin: - ANSWER Si base unit of temperature. Unit symbol (K).
Mega: - ANSWER Metric prefix one million of the base unit. 10^6 Unit
symbol (M).
Kilo: - ANSWER Metric prefix 1/1000 or 10^3. Unit symbol (k).
Deci: - ANSWER Metric prefix 1/10th or 10^(-1) (0.1). Unit symbol (d).
Centi: - ANSWER Metric prefix 1/100th or 10^(-2) (0.01). Unit symbol (c).
Milli: - ANSWER Metric prefix 1/1000th or 10^(-3) (0.001). Unit symbol (m).
Micro: - ANSWER Metric prefix 1/millionth of the base unit. 10^(-6)
(0.000001)
Nano: - ANSWER Metric prefix 1/billionth 10^(-9) (0.000000001). Unit
symbol (n).
, Derived Units: - ANSWER What is produced when the base units/quantities
are combined.
Triple Beam Balance: - ANSWER Instrument used to measure mass.
Graduated Cylinder: - ANSWER Instrument used to measure volume of a
liquid.
Direct Relationship: - ANSWER When an increase of one variable results in
an increase of the other, or a decrease of one results in a decrease of the
other.
Inverse Relationship: - ANSWER When one variable increases and the
other one decreases, or when one decreases and the other increases.
Speed: - ANSWER The distance an object travels per unit of time.
Velocity: - ANSWER The speed and direction of a moving object.
Acceleration: - ANSWER Chang in an object's velocity; occurs when an
object:
*speeds up
*slows down &/or
*changes direction
Force: - ANSWER A push or pull exerted on an object.
Combined Forces: - ANSWER Two or more forces acting in the same
direction on the same object. They add to produce a net force that is
stronger than any one of the forces.
Net Force: - ANSWER The sum of all forces acting on an object.
Opposing Forces: - ANSWER Two forces of the same magnitude acting on
the same object in opposite directions.
Balanced Forces: - ANSWER Forces that combine to produce a net force
of zero.
