Introduction to Science Concepts

Definition of Science

• A systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

Key Characteristics

• Empirical Evidence: Science relies on observable and measurable evidence.
• Reproducibility: Experiments and findings should be replicable by others.
• Falsifiability: Scientific claims must be testable and able to be proven false.

Major Branches of Science

1. Natural Sciences: Study of natural phenomena.

   • Physics
   • Chemistry
   • Biology
   • Earth Science

2. Formal Sciences: Study of abstract concepts.

   • Mathematics
   • Logic
   • Statistics

3. Social Sciences: Study of societies and human behavior.

   • Psychology
   • Sociology
   • Economics
   • Political Science

4. Applied Sciences: Practical use of scientific knowledge for practical purposes.

   • Engineering
   • Medicine
   • Environmental Science

Scientific Method

1. Observation: Gathering information through the senses.
2. Hypothesis: Formulating a testable statement or prediction.
3. Experimentation: Conducting experiments to test the hypothesis.
4. Analysis: Interpreting data and results.
5. Conclusion: Summarizing findings; may support or refute the hypothesis.
6. Communication: Sharing results with the scientific community.
