SCIENCE QUIZ

Scientific Method

A procedure made to discover facts, minimize bias, and obtain reliable results.

Observation

Using the 5 senses (sight, touch, etc.) to study something.

Qualitative Observation

Uses words to describe characteristics (e.g., texture, color, smell, sound, etc).

Quantitative Observation

Uses values and numbers to describe characteristics.

Inference

An explanation based on past experience or prior knowledge.

Formulating Questions

Asking specific questions based on observations.

Hypothesis

A possible and reasonable explanation for a problem that can be tested.

Experimental Data

Notes, graphs, and tabulations recorded during an experiment.

Analyzing Data

The interpretation and analysis of collected data.

Conclusion

A decision drawn from the results and data of an experiment.

Independent Variable

The variable that is manipulated or changed in an experiment.

Dependent Variable

The variable that depends on the independent variable and is measured.

Constant Variable

A variable that remains unchanged throughout the experiment.

D.R.Y M.I.X

A method to graph independent (manipulated) and dependent (responding) variables.

Experimental Setup

The specific arrangement and conditions under which an experiment is conducted.

Controlled Setup

The basis for comparison that does not receive the treatment in an experiment.

Bob’s Observation Example

Bob noticed he got a low score on his science test, using his sight.

Bob’s Inference Example

Bob infers he should study harder based on his low score.

Bob’s Question Example

Bob asks, 'Will studying harder actually improve my test scores?'

Bob’s Hypothesis Example

If I spend at least two hours a day studying, I will achieve better grades.

Bob’s Experimenting Example

Bob compares himself to a classmate who studies only 30 minutes a day.

Bob’s Data Collection Example

Bob uses graphs and charts to gather information about test scores.

Bob's Conclusion Example

Bob concludes he needs to study harder and use new methods to improve grades.

Variables

Factors and conditions that affect the outcome of an experiment.

Types of Variables

Independent, dependent, and constant variables in an experiment.

Manipulated Variable

Another term for independent variable, changed and controlled by the researcher.

Responding Variable

Another term for dependent variable, measured to see effects of changes.

Fair Experiment

An experiment that controls variables to ensure reliable results.

Framework of Experiment

The structure and organization of the scientific experiment.

Experimental Group

The group in an experiment that receives the treatment or manipulation of the independent variable.

Control Group

A group in an experiment that does not receive the treatment, serving for comparison.

Research Question

A question that guides the focus of an experiment.

Scientific Conclusion

The outcome of research that draws upon evidence from data analysis.
