Study Notes
Definition of Science
- Systematic study of the natural world.
- Involves observation, experimentation, and analysis.
- Aims to understand phenomena and establish laws.
Scientific Method
- Observation: Gathering data through the senses.
- Question: Formulating a specific inquiry based on observations.
- Hypothesis: Proposing an explanation or prediction.
- Experiment: Testing the hypothesis through controlled methods.
- Analysis: Evaluating data to determine whether it supports the hypothesis.
- Conclusion: Drawing insights and making inferences based on analysis.
- Repetition: Repeating experiments for validation.
- Communication: Sharing findings with the scientific community.
Branches of Science
- Physical Sciences: Study of non-living systems (e.g., physics, chemistry).
- Life Sciences: Study of living organisms and life processes (e.g., biology, ecology).
- Formal Sciences: Study of formal systems (e.g., mathematics, logic).
- Applied Sciences: Practical application of scientific knowledge (e.g., engineering, medicine).
Major Scientific Theories
- Theory of Evolution: Explains the diversity of life through natural selection.
- Atomic Theory: Describes the structure and behavior of matter.
- Germ Theory: Asserts that microorganisms cause disease.
- Plate Tectonics: Explains the movement of Earth's plates and geological phenomena.
Key Principles in Science
- Reproducibility: Experiments should yield consistent results when repeated.
- Peer Review: Scientific work is evaluated by others in the field for quality and validity.
- Falsifiability: Hypotheses must be testable and capable of being proven false.
- Objectivity: Scientists strive for impartiality and minimizing bias in research.
Importance of Science
- Advances knowledge and understanding of the universe.
- Drives technological innovation and development.
- Informs policy and decision-making in public health, environment, and technology.
- Encourages critical thinking and problem-solving skills.
Definition of Science
- Science is the systematic study of the natural world using observation, experimentation, and analysis
- The aim is to understand phenomena and establish general laws that explain observed patterns.
Scientific Method
- The scientific method is a systematic approach to investigating the natural world
- It uses observations, experiments, and analysis to test hypotheses and draw conclusions.
- The steps are observation, question, hypothesis, experiment, analysis, conclusion, repetition, and communication.
Branches of Science
- Physical Sciences study non-living things, including physics and chemistry.
- Life Sciences focus on living things and life processes, including biology and ecology.
- Formal Sciences deal with abstract systems, such as mathematics and logic.
- Applied Sciences involve the practical application of scientific knowledge, such as engineering and medicine.
Major Scientific Theories
- Theory of Evolution explains the diversity of life on Earth through natural selection, a process where organisms with advantageous traits survive and reproduce more successfully.
- Atomic Theory describes the structure and behavior of matter at its smallest units, atoms. It provides a foundation for understanding chemical reactions.
- Germ Theory explains that microscopic organisms, called germs, cause disease. This theory revolutionized healthcare and led to preventive measures like vaccines and antibiotics.
- Plate Tectonics explains the movement of Earth's outermost layer, the lithosphere, which is broken into large plates. It helps understand geological phenomena like earthquakes, volcanoes, and the formation of mountains.
Key Principles in Science
- Reproducibility: Scientific experiments must produce consistent results when repeated by different people.
- Peer Review: The scientific community evaluates research through peer review to ensure quality and validity.
- Falsifiability: Scientific hypotheses must be testable and capable of being proven wrong.
- Objectivity: Scientists strive for impartiality in their research, minimizing bias.
Importance of Science
- Advances knowledge and understanding of the universe.
- Drives technological innovation and development.
- Informs policy and decision-making in public health, environment, and technology.
- Encourages critical thinking and problem-solving skills.
