Study Notes

The Scientific Method

A procedure for investigating questions about the world
Involves experimentation to collect empirical data
Background research informs the hypothesis, which proposes an explanation
Empirical data is verifiable through observation or experience
Conclusion is formed based on data, supporting or rejecting the hypothesis

History of The Scientific Method

Used unofficially since ancient times
First documented by Sir Francis Bacon in 1620
Ibn al-Haytham, a Muslim scholar, outlined steps before Bacon in the early 1000s
Issac Newton refined the process after Bacon, emphasizing inductive and deductive reasoning

Variations in the Scientific Method

Follows a general pattern but varies between disciplines
Psychologists use surveys, while ecologists use different methods
Scientists studying extinct species require different tools than those studying living species

Steps of the Scientific Method

Ask a Question: An observation leads to a question about the world
Conduct Background Research: Investigate existing knowledge on the topic
Formulate a Hypothesis: An educated prediction answering the question, specific and testable
Design and Conduct an Experiment: Test the hypothesis accurately, controlling all factors but the independent variable
Analyze the Data: Interpret the collected data, looking for significant differences
Draw a Conclusion: Determine whether the data supports or refutes the hypothesis

The Formation of a Scientific Theory

Hypotheses are rarely definitively proven, leaving room for error
Scientists reach a consensus on an explanation but acknowledge the possibility of future discoveries
A scientific theory, supported by peer-reviewed experiments, is a robust explanation for the natural world
Theories are widely believed to be true, but can change with new discoveries
Examples of common scientific theories include Einstein's Theory of Gravity, the Theory of Evolution, and the Big Bang Theory

Scientific Method: Beliefs and Biases

Bias can affect data interpretation
Prejudices towards an outcome can influence the way data is collected and interpreted
Peer review and repeated testing help mitigate bias and ensure scientific rigor
