Study Notes
Branches of Basic Science
-
Natural Sciences:
- Study of natural phenomena and laws of nature
- Includes:
- Physics: study of matter, energy, and fundamental laws of the universe
- Chemistry: study of composition, properties, and reactions of matter
- Biology: study of living organisms and their interactions
-
Formal Sciences:
- Study of formal systems, languages, and structures
- Includes:
- Mathematics: study of numbers, quantities, and shapes
- Logic: study of reasoning, argumentation, and inference
- Computer Science: study of computation, algorithms, and information processing
Key Concepts
-
Scientific Method:
- Systematic process for developing and testing scientific knowledge
- Involves:
- Observation
- Hypothesis
- Prediction
- Experimentation
- Analysis
- Conclusion
-
Theories and Laws:
- Theories: well-substantiated explanations for a set of phenomena
- Laws: concise, mathematical descriptions of natural phenomena
-
Measurement and Units:
- Importance of precise measurements in scientific research
- Use of standardized units (e.g. SI units) to ensure consistency and accuracy
Key Principles
- Objectivity: scientific knowledge should be based on empirical evidence and unbiased observation
- Empiricism: scientific knowledge should be derived from sensory experience and observation
- Rationalism: scientific knowledge should be based on reason and logical inference
- ** Parsimony**: scientific theories should be as simple as possible, while still explaining the data

Key Concepts
Scientific Method
- Is a systematic process for developing and testing scientific knowledge
- Involves observation, hypothesis, prediction, experimentation, analysis, and conclusion
Theories and Laws
- Theories are well-substantiated explanations for a set of phenomena
- Laws are concise, mathematical descriptions of natural phenomena
Measurement and Units

- Empiricism: scientific knowledge should be derived from sensory experience and observation
- Rationalism: scientific knowledge should be based on reason and logical inference
- Parsimony: scientific theories should be as simple as possible, while still explaining the data
Hypothesis
- A hypothesis is a proposed explanation or assumption made to explain a phenomenon or solve a problem.
Key Characteristics
- A hypothesis must be testable to prove or disprove it through experimentation or observation.
- A hypothesis should be specific, clearly and concisely stating what is expected to happen.
- A hypothesis must be falsifiable, able to be proven wrong.
- A hypothesis should be simple, concise, and easy to understand.
Types of Hypotheses
- Null Hypothesis: states there is no significant difference or relationship between variables.
- Alternative Hypothesis: states there is a significant difference or relationship between variables.
Steps in Hypothesis Formation
- Make an observation: identify a phenomenon or problem that sparks curiosity.
- Ask a question: formulate a question based on the observation.
- Research: gather information and review existing knowledge related to the question.
- Formulate a hypothesis: propose a possible explanation or solution based on research.
Importance of Hypotheses
- Guides experimentation: provides direction for experimentation and data collection.
- Provides a framework: helps organize and structure research.
- Encourages critical thinking: promotes critical thinking and analysis.
Common Errors
- Confusing a hypothesis with a theory: a hypothesis is a specific, testable statement, whereas a theory is a broader explanation that has been extensively tested and supported.
- Failing to test the null hypothesis: the null hypothesis should be tested and proven wrong before accepting the alternative hypothesis.
