Introduction to Science Definitions and Branches

Study Notes

Definition of Science

Systematic enterprise that builds and organizes knowledge.
Utilizes observation, experimentation, and reasoning.

Branches of Science

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

Scientific Method

Observation
- Identifying a phenomenon or problem.
Research
- Gathering existing information relevant to the observation.
Hypothesis
- Formulating a testable statement or prediction.
Experimentation
- Conducting controlled tests to evaluate the hypothesis.
Analysis
- Interpreting data and results to draw conclusions.
Conclusion
- Determining if the hypothesis is supported or refuted.
Communication
- Sharing results with the scientific community.

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 describes some aspect of the world.
Variable: Any factor that can change in an experiment (independent, dependent, controlled).
Peer Review: Process by which scientific work is evaluated by other experts in the field before publication.

Importance of Science

Advances technology and medicine.
Informs public policy and environmental conservation.
Enhances understanding of natural phenomena.
Encourages critical thinking and problem-solving skills.

Interdisciplinary Nature

Science often overlaps various fields (e.g., biochemistry, astrophysics).
Collaborations enhance research and knowledge.

Ethical Considerations

Integrity in research and experimentation.
Ethical treatment of subjects (human and animal).
Responsibility in the application of scientific knowledge.

Definition of Science

Systematic enterprise aimed at building and organizing knowledge.
Involves observation, experimentation, and reasoning to draw conclusions.

Branches of Science

Natural Sciences: Focus on the study of the natural world, including disciplines like physics, chemistry, and biology.
Formal Sciences: Explore abstract concepts such as mathematics and logic, emphasizing theoretical frameworks.
Social Sciences: Investigate human societies and behavior, with fields like psychology and sociology examining social dynamics.
Applied Sciences: Concerned with the practical application of scientific knowledge in areas such as engineering and medicine.

Scientific Method

Observation: The first step involves identifying a phenomenon or problem that requires investigation.
Research: Gathering existing information and knowledge relevant to the observation aids in formulating a basis for further inquiry.
Hypothesis: A testable statement or prediction about the phenomenon is developed based on the gathered data.
Experimentation: Controlled tests are conducted to evaluate the validity of the hypothesis.
Analysis: Data obtained from experimentation is interpreted to discern patterns and draw conclusions.
Conclusion: Determines whether the original hypothesis is supported or refuted based on analysis.
Communication: Results are shared with the scientific community to contribute to broader knowledge.

Key Concepts in Science

Theory: A comprehensive explanation based on substantial evidence and research, providing insights into natural phenomena.
Law: A concise statement that describes consistent outcomes observed through repeated experimentation, encapsulating a fundamental principle of nature.
Variable: Factors that can be manipulated in an experiment, categorized as independent (manipulated), dependent (measured), and controlled (held constant).
Peer Review: The process where scientific work is critically assessed by other experts in the field to ensure validity and reliability before publication.

Importance of Science

Drives advancements in technology and medicine, contributing significantly to societal progress.
Informs public policy decisions and aids in environmental conservation efforts.
Enhances comprehension of natural phenomena, fostering a deeper appreciation of the world.
Cultivates critical thinking and problem-solving skills essential for personal and professional development.

Interdisciplinary Nature

Science often intersects various fields, exemplified in domains like biochemistry and astrophysics.
Collaborative efforts among different scientific disciplines enrich research outcomes and expand collective knowledge.

Ethical Considerations

Emphasizes integrity in research practices and scientific experimentation.
Advocates for the ethical treatment of research subjects, including both human and animal participants.
Highlights the responsibility that comes with applying scientific knowledge in society.
