An organized way of gathering and analyzing evidence about the natural world.
Science
How people modify the world around them to meet their needs or to solve practical problems
technology
The study of the properties of matter and how matter changes
chemistry
Branch of science that involves the study of the physical world: energy, matter and how they are related.
physics
the study of the earth, specifically rocks and the planet's crust
geology
The scientific study of the universe, moon, stars, planets, stars
astronomy
The study of life and living things
biology
Process of noticing and describing events or processes in a careful, orderly way
observation
A systematic approach used in scientific study that typically includes observation, a hypothesis, experiments, data analysis, and a conclusion
scientific method
A proposed, scientifically testable explanation for an observed phenomenon.
hypothesis
The part of an experiment that remains the same
Constant, control
factor in an experiment that a scientist purposely changes; also known as independent variable
Manipulated variable
factor in an experiment that a scientist wants to observe, which may change in response to the manipulated variable; also known as a dependent variable
Responding variable
An experiment in which only one variable is manipulated at a time.
Controlled experiment
an explanation of observations or events that is based on knowledge gained from many observations and investigations
Scientific theory
statement based on repeated experimental observations that describes some aspects of the universe; proven and accepted to be true
Scientific law
A simplified version of something complex used, for example, to analyze and solve problems or make predictions.
model
A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10.
Scientific notation
Distance between two points, units in the metric system (SI) are the meter
length
A measure of the amount of matter in an object
mass
Amount of space occupied by an object
volume
A measure of how much mass is contained in a given volume.
density
A ratio of equivalent values used to express the same quantity in different units; is always equal to 1 and changes the units of a quantity without changing its value.
Conversion Factor
The degree to which repeated measurements show the same result.
precision
The degree of closeness of measurements of a quantity to the actual (or accepted) value.
accuracy
All the digits that can be known precisely in a measurement, plus a last estimated digit
significant figures
An instrument used to measure temperature, average Kinetic Energy
thermometer
The process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it.
Analysis
The steepness of a line on a graph
slope
An organized procedure to study something under controlled conditions
experiment
Units used in measuring the temperature
Kelvin, Celsius.
Basic unit of volume in the metric system
Liter
SI unit of length
meter
Unit of time
Second
a relationship in which the ratio of two variables is constant
Direct Proportion
the relation between quantities whose ratio remains constant, when A changes then B changes by the same factor; also called direct ratio
is a relationship in which an increase in one quantity is accompanied by a decrease in the other, or vice versa. Example: the time required for a car trip decreases as the speed increases, and increases as the speed decreases, so the time required is inversely proportional to the speed of the car.
Inverse Proportion
An axis-type graph in which data points are joined by a line.
Line Graph
A graph that uses horizontal or vertical bars to display data
Bar graph
a graph that highlights segments of a circle to show simple distribution patterns
Pie graph
Results of the laboratory investigation
Conclusion
