Unit 1 List 2 Experimental Design Flashcards
Claim
A concluding statement that is used to explain a cause and effect relationship.
Constant
The factors that do not change during the experiment.
Evidence
Information collected via rigorous scientific methods.
Experimental Bias
Occurs when scientists’ hypotheses influence their results, even if involuntarily.
Experimental Control
An element that remains unchanged or unaffected by other variables.
Experimental Procedure
The manner in which an experiment is carried out.
Hypothesis
A statement about a specific research question, and it outlines the expected result of the experiment.
Manipulated Variable
A factor that is purposefully and specifically changed by the experimenter.
Qualitative Data
Data representing information and concepts that are not represented by numbers.
Quantitative Data
Measures of values or counts and are expressed as numbers.
Reason
A problem-solving process that involves critical thinking in relation to content, procedural, and epistemic knowledge.
Responding Variable
The part of an experiment that a scientist measures and observes closely for a change or a response.
Scientific Method
The process of objectively establishing facts through testing and experimentation.
Scientific Model
A physical and/or mathematical and/or conceptual representation of a system of ideas, events or processes.
Scientific Question
A question that is written in a way that is helpful for completing scientific investigations.
Scientific Theory
A well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment.
Trends In Data
A general change in one variable compared to another over a period of time.
Valid Experiment
When the results are correct, or true.
