Study Notes
Scientific Method
- Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
- The scientific method is a cyclical process used to investigate natural phenomena.
- Key steps in the scientific method include:
- Observation: noticing a phenomenon or posing a question.
- Hypothesis: proposing a testable explanation for the observation.
- Prediction: stating what the expected outcome will be if the hypothesis is correct.
- Experiment: designing and conducting a controlled investigation to test the hypothesis.
- Analysis: interpreting the results of the experiment, and determining whether the outcome supports or refutes the hypothesis.
- Conclusion: drawing a conclusion based on the evidence obtained from observations and experiments.
- The scientific method is iterative. Results from one investigation may lead to new questions, hypotheses, and further investigations.
Branches of Science
- Science is broadly categorized into various disciplines (branches):
- Biological sciences: study of living things, including botany (plants), zoology (animals), and microbiology (microorganisms).
- Physical sciences: study of non-living matter, including physics, chemistry, and astronomy
- Earth sciences: study of Earth's structure, processes, and history, including geology, oceanography, and meteorology.
- These branches often overlap and share methodologies. For example, a geologist might use physics to study the movement of tectonic plates.
Scientific Theories and Models
- A scientific theory is a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
- Scientific theories are supported by a vast body of evidence and are the most reliable explanations we have for how the natural world works.
- Scientific models are simplified representations of complex systems or phenomena. Models are used to:
- Visualize complex processes
- Predict future outcomes
- Test hypotheses
Scientific Laws
- A scientific law describes a fundamental relationship or regularity in nature.
- Laws are concise statements about a particular event and are often expressed mathematically.
- Examples of scientific laws include Newton's laws of motion and the law of conservation of energy.
- Laws are based on extensive observations and are generally considered universally true.
Ethical Considerations
- Scientific research must adhere to ethical principles:
- Maintaining honesty and integrity in data collection, analysis, and reporting.
- Ensuring that the safety of humans and animals taking part in research is protected.
- Protecting the environment.
- Ensuring informed consent for human participants
Scientific Communication
- Effective scientific communication is crucial to sharing knowledge and advancing science.
- Scientists communicate through various means, including:
- Peer-reviewed journal articles
- Conferences and presentations
- Scientific reports.
Tools of Science
- Scientific investigation relies on a diverse array of tools and technologies:
- Microscopes for analyzing microscopic structures
- Telescopes to observe celestial bodies
- Spectrometers for analyzing light and other electromagnetic radiation
- Computers and software for data analysis and modeling.
