   • Computer Science: Study of computation and information systems.

5. Social Sciences

   • Psychology: Study of behavior and mental processes.
   • Sociology: Study of human society and social behavior.
   • Anthropology: Study of human cultures and societies.

Scientific Method

• Observation: Gathering data and noting phenomena.
• Hypothesis: Formulating testable explanations.
• Experimentation: Conducting tests to validate or refute hypotheses.
• Analysis: Interpreting data and drawing conclusions.
• Reporting: Sharing findings with the scientific community.

Importance of Science

• Advances technology and medicine.
• Informs policy-making and environmental protection.
• Enhances understanding of natural and social phenomena.

Key Concepts

• Theory: A well-substantiated explanation of an aspect of the natural world.
• Law: A statement based on repeated experimental observations that describe some aspect of the world.
• Variables: Factors that can change in an experiment (independent, dependent, controlled).

Current Trends in Science

• Interdisciplinary research combining various scientific fields.
• Emphasis on sustainability and environmental science.
• Growth of AI and data science in research methodologies.

Ethical Considerations

• Importance of ethical standards in research practices.
• Issues include animal testing, human subjects, and environmental impact.
• Scientific integrity and transparency are crucial for public trust.
