Variables
What you want to change each time in an experiment in order to test something.
(The Cause)
Manipulated/ Independent
Variable
The first step in the Scientific Method that guides your investigation.
It focuses on a problem and what you want to find out.
Purpose/ Question
A measure of distance.
Length
Information gathered with your 5 senses
Qualitative Observation
Grouping things together that are alike based on their properties.
Classification
What you measure at the end of each test during an experiment.
(The Effect)
Responding/ Dependent
Variable
The second step of the Scientific Method. This step helps you discover more about your question.
Research.
How much space an object or liquid takes up
Volume
Information gathered by measuring
Quantitative Observation.
Comparing things to one another or a tool
Measurement
Things that stay the same in order to keep the tests in an experiment fair and the results reliable.
Controlled Variables
The third step of the Scientific Method. It creates a statement that answers your question and can be tested.
Hypothesis
How much matter an object contains
Mass
A conclusion based on observations
Inference
A statement or belief that can be tested
Hypothesis
Name the Manipulated/Independent Variable:
The more time spent studying for a test, the higher the grade the student will earn.
Manipulated Variable: The amount of time the student studied.
The fourth step of the Scientific Method. This is what you do when you test your hypothesis.
Experiment
How hot or cold something is
Temperature
The boy wanted to know how heavy his baseball was, so he used a balance scale to get the mass. Is this a qualitative or quantitative observation?
Quantitative
An educated guess
Prediction
Name the Responding/Dependent Variable:
According to research, a person's weight can depend on how many times per week they exercise.
Responding Variable:
A person's weight.
The last step of the Scientific Method. This step focuses on the results of your experiment.
Conclusion
Name 2 tools used for measurement
A ruler, meter stick, balance scale, thermometer, graduated cylinder
