Branches of Science

Branches of Science

• Natural Sciences:
  • Study of natural phenomena and laws of nature
  • Divided into:
    • Physical Sciences: physics, chemistry, astronomy
    • Life Sciences: biology, botany, zoology
• Formal Sciences:
  • Study of formal systems and languages
  • Includes:
    • Mathematics: numbers, geometry, algebra
    • Logic: reasoning, argumentation
• Applied Sciences:
  • Practical application of scientific knowledge
  • Includes:
    • Engineering: design, construction, maintenance
    • Medicine: health, disease, treatment
    • Technology: development, application of scientific knowledge

Scientific Method

• Observation: identify problem or question
• Hypothesis: propose explanation or solution
• Prediction: forecast outcome based on hypothesis
• Experimentation: test hypothesis through data collection
• Analysis: interpret data, draw conclusions
• Conclusion: support or reject hypothesis

Key Scientific Concepts

• Theory: well-substantiated explanation for a set of phenomena
• Law: statement describing a consistent pattern of behavior
• Hypothesis: proposed explanation for a specific phenomenon
• Model: simplified representation of a system or process
• Variable: factor that can change or be changed in an experiment

Important Scientific Tools

• Microscope: instrument for observing microscopic objects
• Telescope: instrument for observing distant objects
• Laboratory: controlled environment for experimentation
• Computer: tool for data analysis, simulation, and modeling
• Statistics: mathematical techniques for data analysis

• Technology is a part of Applied Sciences, involving the development and application of scientific knowledge.

Scientific Method

• Observation is the first step in the scientific method, where a problem or question is identified.
• A hypothesis is proposed to explain the observed phenomenon.
• A prediction is made based on the hypothesis.
• Experimentation is conducted to test the hypothesis through data collection.
• Analysis involves interpreting data and drawing conclusions.
• The conclusion is drawn based on the data, either supporting or rejecting the hypothesis.

Key Scientific Concepts

• A scientific theory is a well-substantiated explanation for a set of phenomena.
• A scientific law is a statement describing a consistent pattern of behavior.
