What are “observations” scientific method?
The scientific method begins by making observations related to the topic under the investigation. These observations are used to formulate a tentative explanation known as the hypothesis.
What is the “Hypothesis” Scientific method?
An important attribute of a hypothesis is that it must be testable. The testing of the proposed hypothesis involves designing and performing a controlled experiment to obtain data that can be used to support, reject, or modify the hypothesis.
What is the independent variable?
The independent variable is one that can be changed but is determined before the experiment occurs.
What is the dependent variable?
A dependent variable is one that is determined from the results of the experiment.
What is the analysis of data?
Analysis of data is conducted using sufficient information collected during the experiment. From the interpretations of data, conclusions are drawn.
What is a theory?
If many investigators working independently can validate the hypothesis by arriving at the same conclusion, the explanation can be a theory. A theory serves as the explanation from a summary of known experiments and supporting evidence unless it is disproved by new information.
What are the five components of the scientific method?
Observations -> Hypothesis -> Experiment -> analysis of data -> Conclusion.
