• Ethical implications of genetic engineering and biotechnology.

Definition of Science

• Science is a systematic method for building and organizing knowledge.
• It involves observing, describing, investigating, and explaining natural phenomena.

Branches of Science

• Natural Sciences: Study of the natural world, including physics, chemistry, biology, and earth science.
• Social Sciences: Analyze human behavior and societies, including psychology, sociology, anthropology, and economics.
• Formal Sciences: Focus on abstract concepts and systems such as mathematics, logic, and statistics.
• Applied Sciences: Apply scientific knowledge to practical applications, including engineering, medicine, and environmental science.

Scientific Method

• The scientific method is a structured approach to scientific inquiry that includes observation, question formation, hypothesis creation, experimentation, analysis, and conclusion drawing.
• Observation: Careful noticing and describing phenomena.
• Question: Forming questions based on observations.
• Hypothesis: An explanation or prediction meant to be tested.
• Experimentation: Testing the hypothesis through controlled experiments.
• Analysis: Evaluating the results and data from experiments.
• Conclusion: Drawing conclusions based on the analysis.

Key Concepts

• Theory: A well-established explanation of a natural phenomenon, backed by extensive evidence.
• Law: A description of a phenomenon consistently observed under certain conditions, such as the Law of Gravity.
• Hypothesis: A testable statement about the relationship between variables.
• Variable: Any factor that can change in an experiment.
  • Independent Variable: The factor that is manipulated.
  • Dependent Variable: The factor that is measured or observed.
  • Controlled Variable: Factors kept constant throughout the experiment.

Importance of Science

• Science drives technological advancements by applying scientific knowledge for practical purposes.
• Science informs public policy and decision-making by providing evidence-based information for policy development.
• Science helps us understand natural phenomena and the environment, leading to conservation efforts and informed environmental management.
• Science enhances critical thinking skills and problem-solving abilities by promoting logical reasoning, evidence evaluation, and data interpretation.

Notable Scientists

• Albert Einstein: Developed the theories of relativity that revolutionized our understanding of space, time, gravity, and the universe.
• Isaac Newton: Formulated the laws of motion and universal gravitation, fundamental to classical physics.
• Charles Darwin: Proposed the theory of evolution by natural selection, a cornerstone of modern biology.
• Marie Curie: Pioneered research on radioactivity, leading to groundbreaking discoveries in nuclear physics.

Current Trends in Science
