Scientific method
Bias
A preformed judgment or unfavorable opinion about something
Interference (assumption)
An explanation of why something happened. An inference is how you explain what you observed.
The item or group of items which are the standard for comparison. A test that is performed by removing the independent variable.
Control
The measure of how long something is; the measurement of anything from end to end; metric base unit= meters.
An observation that is based upon something that cannot be measured (quality). (Examples: sweetness, color, smell, taste)
Qualitative data
Experimental Design Steps: In Order
Problem, Research, Hypothesis, Experiment, Analysis, Conclusion
The steps take to carry out an experiment
The part of the experiment that the scientists changes on purpose
Independent variable
The amount of space something fills up or occupies; metric base unit= liters.
Volume
Measurable data gathered in a numeric form (quantity). (Examples: length, volume, mass, temperature, pH, pressure)
Quantitative data
To examine something closely using all of your senses. An observation does not include opinions. Objective v Subjective
Observation
Measurements and facts obtained from the experiment. Dara are used as a basis for drawing conclusions.
Data
The part of the experiment that changes as a result of the independent variable. The dependent variable is the change that you are measuring.
Mass
The amount of matter in something; metric base unit = grams.
A statement or quality of being true and reasonable.
Validity
Hypothesis
A possible answer to your experiment's problem. It is a prediction that can be tested.
An examination of the results of the experiment. A search for relationships within the data (often by using graphs)
Analysis
A scientifically testable general principle offered to explain something in nature. It can accurately predict the outcome of future experiments and observations.
Theory
A measurement system based on 10’s and is used internationally.
Metric System
Invalid
A statement or quality of being false and not reasonable
The question that the experiment is designed to answer. It is the reason that you are doing the experiment.
Problem
Compares the hypothesis to the experiments results. A search for relationships within the data.
Conclusion
Law
Something that has been proven to occur over and over again whenever certain conditions exist or are met.

Metric Base Unit (meters, liters, grams)
Deci (0.1), Centi (0.01), Milli (0.001)
The group that has variables acting upon it so that it can be compared with the results of the control group.
