Study Notes

Scientific Method

Science is a systematic approach to understanding the natural world.
The scientific method involves observation, question formation, hypothesis development, experimentation, data analysis, and conclusion drawing.
Observation involves noticing a phenomenon or pattern in the natural world.
Questions arise from observations and seek to explain or understand the observed phenomenon.
A hypothesis is a testable explanation for the observed phenomenon.
Experiments are designed to test the hypothesis by manipulating variables and collecting data.
Data analysis involves interpreting the collected data to determine whether the hypothesis is supported or rejected.
Conclusions are drawn based on the analysis of the data, potentially leading to further research or refinement of the hypothesis.

Branches of Science

Science is broadly categorized into physical, biological, and Earth and space sciences, as well as other disciplines.
Physical sciences include physics and chemistry, which study matter and energy.
Biological sciences study living organisms and their interactions.
Earth and space sciences study the Earth and universe.

The Scientific Process

Scientists use a variety of tools and techniques.
Observation often involves instruments to gather data more precisely.
Experiments allow for controlled conditions to verify the hypothesis.
Validity and reliability matter in the scientific method. Research must be reproducible for validation.

Scientific Theories and Laws

A scientific theory explains a phenomenon based on a broad body of evidence. It is supported by many verified observations and experiments.
Scientific laws describe observed phenomena in predictable ways. They are often expressed as mathematical equations.
Theories are broader explanations, whereas laws describe specific relationships or behaviors.

Scientific Communication

Scientists share their findings through publications, presentations, and conferences.
Peer review is important because it validates the quality and reliability of the research. Scientific findings benefit from scrutiny by other experts.
Scientific discourse is essential for the advancement of knowledge. Sharing research allows for community feedback and collaboration.

Nature of Science

Science is based on evidence and testable explanations. Claims must be supported by empirical evidence from repeatable experiments.
Science is a process of inquiry and involves continual refinement of knowledge. Science evolves as new evidence emerges.
Science is limited by the nature of the phenomena studied and the limitations of observation and experimentation.
Science is tentative; with new discoveries, existing understanding could be refined or even fundamentally altered.
Science is collaborative and builds upon prior knowledge; it is not a solitary endeavor.

Ethical Considerations in Science

Ethical considerations are paramount in scientific research.
Ethical guidelines are essential for responsible conduct of research. Respect for living subjects in biological research and data protection for various fields are critical.
Scientific research has to align with ethical and societal values. A consideration of potential harm is essential.
