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
