Scientific Method and Key Concepts

Study Notes

Scientific Method

Science is a systematic approach to understanding the natural world.
The scientific method is a process used to investigate the natural world and acquire new knowledge.
Key steps in the scientific method include: observation, question formation, hypothesis development, prediction, experimentation, analysis, and conclusion.

Key Concepts in Science

Hypothesis: A proposed explanation for an observation, which can be tested.
Theory: A well-substantiated explanation of some aspect of the natural world, based on a large body of evidence.
Law: A description of a natural phenomenon based on repeated observations and experiments. It usually describes what happens, while a theory explains why it happens.
Variable: A factor that can change in an experiment, including independent variables (manipulated factors), dependent variables (measured factors), and controlled variables (factors kept constant).

Branches of Science

Natural sciences encompass various disciplines that study the natural world.
Physics: Studies matter, energy, and their interactions.
Chemistry: Studies the composition, structure, properties, and reactions of matter.
Biology: Studies living organisms and their interactions with each other and their environments.
Earth science: Studies the Earth's physical structure, processes, and history.
Astronomy: Studies celestial objects and phenomena.

Scientific Inquiry

Scientific inquiry is the active process of acquiring new knowledge through observation, experimentation, and reasoning.
Critical thinking plays a key role in scientific inquiry. It involves skepticism, careful analysis, and the evaluation of evidence.
Scientific investigations often involve gathering data through various methods including observations, experiments, and measurements.
Communicating results is crucial in science; it allows for peer review, collaboration, and the advancement of knowledge.
Scientific knowledge is always subject to revision and refinement as new evidence emerges.

Scientific Tools and Processes

Scientific tools enable detailed observation and measurement. These include microscopes, telescopes, measuring instruments, and computers.
Data analysis involves organizing and interpreting data collected during investigations.
Mathematical modeling is often used to represent and predict patterns in the natural world.
Models in science are simplified representations of complex systems or processes. Models may be physical, visual, or mathematical.

Scientific Ethics

Scientists are expected to act ethically and with integrity in their research.
Maintaining objectivity and avoiding bias are essential.
Proper data handling, and accurate reporting are critically important.
Plagiarism and fabrication of data are unethical and unacceptable practices which undermine the integrity of science.

The Role of Science in Society

Scientific understanding has profound implications for technological advancement, social policy, and societal well-being.
Scientific discoveries underpin technological innovations and improvements in various fields (medicine, communication, agriculture, etc).
Scientific research can be used to address pressing global challenges like climate change, disease, and resource management.
Scientific literacy is important for individuals to actively participate in public discourse and decision-making processes.
