Understanding the Scientific Method and Principles

• Science employs a systematic and organized methodology for understanding the natural world through observation, experimentation, and analysis.
• This process includes the formulation of theories and laws designed to explain and predict various phenomena.

Core Principles

• Objectivity ensures that scientific investigations remain unbiased, relying on empirical evidence.
• Empirical Evidence is the foundation, as conclusions are derived from observations and experimental data.
• Testability requires that scientific hypotheses and theories can be tested through experiments or observations.
• Falsifiability means any scientific idea can be proven wrong.
• Repeatability is essential, experiments and observations must be repeatable by other scientists to verify results.
• Skepticism drives scientists to question and critically evaluate evidence and claims.

Scientific Method

• Observation involves noticing a phenomenon or identifying a problem that needs addressing.
• Question formulation involves creating a question about the observed phenomenon.
• Hypothesis development includes creating a testable explanation or prediction.
• Experimentation includes designing and conducting experiments to test the hypothesis.
• Analysis refers to analyzing the data collected during the experiment.
• Conclusion development includes either supporting or rejecting the hypothesis based on analysis
• Communication involves sharing results with the scientific community through publications and presentations.

Major Branches

• Natural Sciences focus on studying the physical world.
• Biology involves studying of living organisms including their structure, function, growth, origin, evolution, and distribution.
• Chemistry involves studying matter, its properties, and how it changes.
• Physics focuses on universal laws and principles, including matter, energy, motion, and force.
• Earth Science includes geology (Earth's structure and substance), oceanography (oceans), and meteorology (atmosphere and weather).
• Social Sciences study human society and social relationships.
• Psychology involves studying the human mind and behavior.
• Sociology studies societies and human social behavior.
• Economics involves studying the production, distribution, and consumption of goods and services.
• Formal Sciences study formal systems.
• Mathematics study numbers, quantities, space, and patterns.
• Computer Science involves studying computation and information processing.
• Logic involves studying the principles of valid reasoning.

Scientific Theories and Laws

• Theories offer well-substantiated explanations of the natural world, based on repeatedly confirmed facts.
• Laws are descriptive statements or equations predicting phenomena under specific conditions.

Measurement and Units

• SI Units: The International System of Units is a standardized system of measurement.
• Length is measured in meters (m).
• Mass is measured in kilograms (kg).
• Time is measured in seconds (s).
• Temperature is measured in Kelvin (K).
• Electric Current is measured in Amperes (A).
• Amount of Substance is measured in Moles (mol).
• Luminous Intensity is measured in Candelas (cd).

Data Collection and Analysis

• Quantitative Data is numerical and analyzed statistically.
• Qualitative Data is descriptive, involving characteristics or qualities that cannot be easily measured.
• Statistics utilizes mathematical methods to analyze and interpret data.
• The Mean represents the average of a set of numbers.
• The Median represents the middle value in a set of numbers.
• The Mode represents the most frequent value in a set of numbers.
• Standard Deviation measures the spread of data around the mean.

Tools and Technologies

• Microscopes view small objects or structures.
• Telescopes observe distant objects in space.
• Spectrometers analyze properties of light and electromagnetic radiation.
• Particle Accelerators accelerate particles for studying subatomic particles.
• Computers enable data analysis, modeling, and simulation.

Experiment Design

• Control Groups do not receive the treatment being tested.
• Experimental Groups receives the treatment being tested.
• Variables are factors that can change in an experiment.
• Independent Variables are manipulated by the researcher.
• Dependent Variables are measured to see how they are affected by the independent variable.
• Controlled Variables are kept constant to prevent them from affecting the dependent variable.

Scientific Communication

• Peer Review involves evaluation by experts before publication.
• Scientific Journals publish original research articles.
• Conferences and Presentations are forums for sharing research findings.

Ethics in Science

• Integrity requires honesty and transparency in research.
• Objectivity is avoiding bias in research.
