Definition and Importance of Science

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
It employs methods such as observation, experimentation, and analysis to understand natural phenomena.

Branches of Science

Natural Sciences
- Focus on the physical world and its phenomena.
- Includes:
  - Physics: Study of matter, energy, and forces.
  - Chemistry: Study of substances and their interactions.
  - Biology: Study of living organisms and life processes.
Formal Sciences
- Concerned with formal systems and abstractions.
- Includes:
  - Mathematics: Study of numbers, quantities, shapes, and patterns.
  - Logic: Study of valid reasoning and argumentation.
  - Statistics: Study of data analysis and interpretation.
Social Sciences
- Focus on human behavior and societies.
- Includes:
  - Psychology: Study of mind and behavior.
  - Sociology: Study of social behavior and institutions.
  - Economics: Study of production, consumption, and resource allocation.

Scientific Method

A structured approach to investigation that involves:
1. Observation: Noting phenomena and gathering data.
2. Question: Formulating a question based on observations.
3. Hypothesis: Proposing a testable explanation.
4. Experimentation: Conducting experiments to test the hypothesis.
5. Analysis: Interpreting results and drawing conclusions.
6. Peer Review: Submitting findings for validation by other scientists.
7. Theory Formation: Developing a broader theory if consistent results are obtained.

Key Concepts in Science

Theory: A well-substantiated explanation of an aspect of the natural world.
Law: A statement based on repeated experimental observations that describe an aspect of the world.
Variables: Factors that can change in an experiment (independent, dependent, and controlled).
Control Group: The standard to which comparisons are made in an experiment.

Significance of Science

Advances technology and medicine.
Contributes to solving global challenges (e.g., climate change, health crises).
Enhances understanding of the universe and humanity's place within it.
Encourages critical thinking and informed decision-making.

- Theory Formation: developing a broader theory if consistent results are obtained.

Key Concepts in Science

Theory is a well-substantiated explanation of an aspect of the natural world.
Law is a statement describing an aspect of the world based on repeated experimental observations.
Variables are factors that change in an experiment (independent: manipulated, dependent: measured, controlled: held constant).
Control Group serves as a standard for comparison in an experiment.

Significance of Science

Science advances technology and medicine.
It contributes to solving global challenges such as climate change and health crises.
It enhances our understanding of the universe and our place in it.
It encourages critical thinking and informed decision-making.
