What is science?
What is science?
Science is a way of knowing about the natural world through observation, experimentation, and analysis. It involves a systematic process of asking questions, forming hypotheses, collecting data, and drawing conclusions.
What are natural sciences?
What are natural sciences?
Natural sciences explore the physical world, including living organisms (biology), matter and its properties (chemistry), and forces and energy (physics).
What are formal sciences?
What are formal sciences?
Formal sciences use mathematical and logical reasoning to study abstract concepts, like numbers, shapes, and logic. They provide the tools for understanding and reasoning in other sciences.

Study Notes
Scientific Method
- Science is a systematic approach to understanding the natural world.
- It involves observation, questioning, hypothesis formation, experimentation, data analysis, and conclusion drawing.
- The scientific method is a cyclical process, with findings from one study leading to new questions and investigations.
Branches of Science
- Natural sciences explore the physical world.
- Biology studies living organisms.
- Chemistry investigates matter and its properties.
- Physics explores forces, energy, and motion.
- Earth science examines the Earth's systems and processes.
- Astronomy studies celestial objects.
- Formal sciences use mathematical and logical reasoning to explore abstract concepts.
- Mathematics studies numbers, shapes, and logic.
- Logic examines valid arguments and reasoning.
- Social science investigate human behavior and society.
- Psychology studies the mind and behavior.
- Sociology studies societies and social interactions.
- Economics analyzes production, distribution, and consumption.
- Political science studies government and political systems.
- Anthropology investigates human cultures and societies.
Scientific Principles
- Empirical evidence: Scientific understanding is based on observable and measurable evidence.
- Objectivity: Scientists strive to remove personal biases from their observations and interpretations.
- Reproducibility: Experiments should be designed so that others can repeat them and obtain similar results.
- Falsifiability: A scientific statement or hypothesis must be testable and potentially disproven by evidence.
- Parsimony: When several explanations are possible, the simplest one is usually preferred.
Scientific Tools and Techniques
- Various tools and techniques are used to gather and analyze data in different fields and branches of science. These can include:
- Microscopes to visualize small objects
- Spectrometers to analyze light and other electromagnetic radiation
- Chromatography to separate substances
- Pipettes and other lab equipment for precise measurements
- Statistical analyses to interpret data
Scientific Models
- Models are simplified representations of complex systems or processes.
- They help to visualize, understand, and predict behavior.
- Models can be physical, mathematical, or computational.
- Scientists use various modelling techniques to represent and analyze scientific phenomena.
Ethical Considerations in Science
- Scientific research should always be conducted ethically.
- It is important to consider the potential impact of research on human health and the environment.
- Researchers must adhere to established standards of conduct and safety measures to minimize risks.
- Informed consent and data privacy are important principles in studies involving human subjects.
