Introduction to Science Concepts

Study Notes

Definition of Science

Systematic study of the natural world through observation and experimentation.
Aims to understand and explain phenomena.

Key Concepts in Science

Hypothesis
- A testable prediction based on observations.
Theory
- A well-substantiated explanation of some aspect of the natural world, based on a body of evidence.
Law
- A statement that describes an observable phenomenon; often expressed mathematically (e.g., Newton's laws of motion).

Scientific Method

A systematic approach to research.

Question
- Identify what you want to learn about.
Research
- Gather existing information related to the question.
Hypothesis
- Propose a tentative explanation or answer to the question.
Experiment
- Conduct tests to validate or invalidate the hypothesis.
Analysis
- Examine data collected during experiments.
Conclusion
- Summarize findings and determine if the hypothesis was supported or not.

Branches of Science

Natural Sciences
- Study of natural phenomena (e.g., physics, chemistry, biology).
Social Sciences
- Study of human behavior and societies (e.g., psychology, sociology, economics).
Formal Sciences
- Study of abstract concepts (e.g., mathematics, logic).
Applied Sciences
- Practical applications of scientific knowledge (e.g., engineering, medicine).

Importance of Science

Enhances understanding of the world.
Drives technological advances.
Informs policy and decision-making.
Contributes to solving global challenges (e.g., climate change, health).

Ethical Considerations in Science

Responsibility for the societal impact of scientific research.
Importance of integrity, transparency, and reproducibility in scientific findings.
Ethical implications of experiments, particularly involving human and animal subjects.

Science Communication

Essential for public understanding of scientific concepts.
Engages community in scientific issues and decisions.
Effective communication fosters trust in scientific research.

Definition of Science

Science is the systematic study of the natural world
Scientists use observation and experimentation to understand and explain natural phenomena

A law is a statement that describes an observable phenomenon, often expressed mathematically (e.g., Newton's laws of motion)

Scientific Method

The scientific method is a systematic approach to research
It involves asking a question, gathering research, forming a hypothesis, conducting experiments, analyzing data, and drawing conclusions

Branches of Science

Natural sciences study natural phenomena (e.g., physics, chemistry, biology)
Social sciences study human behavior and societies (e.g., psychology, sociology, economics)
