Introduction to Science and the Scientific Method

Study Notes

Definition of Science

Systematic study of the natural world.
Utilizes observation, experimentation, and evidence-based reasoning.

Key Components

Observation: Gathering data through the senses or instruments.
Hypothesis: A testable statement predicting outcomes based on observations.
Experimentation: Conducting tests to validate or refute hypotheses.
Analysis: Interpreting data to draw conclusions.
Theory: A well-substantiated explanation of some aspect of the natural world.

Scientific Method

Steps involved:
1. Ask a question.
2. Conduct background research.
3. Construct a hypothesis.
4. Test the hypothesis through experimentation.
5. Analyze data and draw conclusions.
6. Communicate results.

Definition of Science

A systematic and rigorous approach to understanding the natural world.
Employs observation, experimentation, and evidence-based reasoning to build knowledge.

Key Components of the Scientific Method

Observation: Gathering information through the senses or instruments.
Hypothesis: A testable prediction based on observations.
Experimentation: Controlled tests designed to validate or disprove hypotheses.
Analysis: Interpreting data to draw conclusions about the hypothesis.
Theory: A well-supported explanation of a natural phenomenon, backed by a large body of evidence.

The Scientific Method: A Step-by-Step Process

Ask a question: Identify a specific area of interest.
Conduct background research: Gather existing knowledge about the question.
Formulate a hypothesis: Propose a testable explanation for the phenomenon.
Test the hypothesis: Conduct controlled experiments to gather data.
Analyze data and draw conclusions: Interpret results and determine if they support or refute the hypothesis.
Communicate results: Share findings with the scientific community.
