Introduction to the Scientific Method
What is the Scientific Method?
The scientific method is a process used by scientists to investigate phenomena, acquire new knowledge, or correct and integrate previous knowledge. It involves making observations, formulating hypotheses, testing predictions, and drawing conclusions.
- Systematic approach to solving problems
- Based on empirical evidence
- Self-correcting through peer review
- Aims for objectivity and reproducibility
The History of Scientific Inquiry
While humans have always sought to understand the world around them, the formalized scientific method as we know it today developed gradually over centuries. From ancient Greek philosophers to Renaissance thinkers like Galileo and Bacon, the evolution of scientific thinking has been marked by an increasing emphasis on empirical evidence and systematic testing.
Aristotle believed heavy objects fall faster than light ones. Nearly 2,000 years later, Galileo challenged this by experimenting with balls of different weights, demonstrating that they fall at the same rate (neglecting air resistance).
The Basic Steps
The scientific method typically consists of several interconnected steps that form a cycle of discovery and refinement. These steps provide a framework for asking questions, gathering information, and reaching conclusions based on evidence.
- Observation: Noticing phenomena in the world
- Question: Asking about what you observe
- Hypothesis: Forming a testable explanation
- Experiment: Testing the hypothesis
- Analysis: Examining experimental results
- Conclusion: Interpreting what the results mean
- Communication: Sharing findings with others
Summary
Learn the fundamental steps of scientific inquiry and how they apply to the scientific method.
Key Takeaways
- The scientific method is a systematic process for investigating natural phenomena
- It includes observation, questioning, hypothesis formation, experimentation, analysis, and conclusion
- Scientific knowledge is provisional and subject to revision based on new evidence
- The method emphasizes objectivity, empirical evidence, and reproducibility

Key Terms
- Scientific Method
- A systematic procedure that consists of observation, hypothesis formation, experimentation, analysis, and conclusion.
- Empirical Evidence
- Information acquired by observation or experimentation, as opposed to reasoning or intuition.
- Reproducibility
- The ability of an experiment to be duplicated by other researchers with the same results.
