- Examples: Geology, Meteorology, Oceanography
Formal Sciences
- Study of abstract concepts and systems
- Examples: Mathematics, Logic, Statistics

Scientific Method

Observation
- Gathering data through senses or instruments
Question
- Formulating a question based on observations
Hypothesis
- Proposing a testable explanation or prediction
Experimentation
- Conducting experiments to test the hypothesis
Analysis
- Analyzing data collected during experiments
Conclusion
- Drawing conclusions based on analysis; revising hypotheses if necessary

Importance of Science
