Pd 1 Flashcards
Science
The search for understanding the natural world through systematic observation and experimentation.
Life Science
The study of living things
Earth Science
The study of the non-living parts of Earth and outer space.
Physical Science
A science that contains the two sub-branches of science: Physics and Chemistry.
Physics
The study of forces, energy, and motion.
Forces
A push or a pull.
Energy
The ability to make something move.
Motion
How things move.
Chemistry
The study of matter and the changes it undergoes.
Matter
Anything with mass and volume.
Mass
The measure of the amount of matter in an object.
Volume
The measure of how much space something takes up.
Hypothesis
An specific educated guess or prediction that can be tested
Law
A highly supported statement that cannot be proven, but may possibly be disproven one day, that says what happens but does not explain why. It is often in mathematical form.
Theory
A very strong explanation of why known laws and facts exist. They never become laws.
Opinion
Just what someone thinks or believes.
Inductive Reasoning
Something that is observed personally and then applied to the world. (from specific to general)
Deductive Reasoning
Something observed about the world and then applied to a specific situation. (from general to specific)
Scientific Method
A systematic, organized way to answer a question.
Valid
It is having a basis in logic or fact; it is testable and able to be accepted and repeated.
Control Set-up
The side of the experiment under “Normal Conditions”
Experimental Set-up
The side of the experiment that has the independent variable.
Independent Variable
The one thing you change between the Control Set-up and the Experimental Set-up.
Dependent Variable
What changes because of the independent variable that you measure in the experiment. (This is what you put in your data table
Constants
What stays the same between your Control Set-up and your Experimental Set-up.
Qualitative Data
Observations using your five senses. (descriptions)
Quantitative Data
Observations of measurement.
Data
Information you collected from your experiment.
Data Table
A table in which you record your data during an experiment to keep your information
Bar Graph
A graph that uses bars to compare things.
Line Graph
A graph that uses lines to show change over time.
Scatter Plots
A graph that uses dots to show the relationships between two different
Positive Correlation
When one factor increases so does the other or when one factor decreases so does the other. (↑↑) (↓↓)
Negative Correlation
When one factor increases the other decreases
↓↑
No Correlation
Shows no relationship found between the factors (random)
Circle Graph
A graph that uses a circle to show parts of a whole or percentages.
( Part / Whole ) X 100 = %
Applied Technology
The application of scientific knowledge to everyday problems.
X - Axis
What you are comparing or time
Y - Axis
Dependent Variable
