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.
