General Science Concepts

Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Scientific knowledge is acquired through observation, experimentation, and the formulation and testing of hypotheses.
Key aspects of the scientific method include observation, hypothesis formation, prediction, experimentation, analysis, and conclusion.
Scientific theories are well-substantiated explanations of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.
Scientific laws describe relationships in nature, often expressed mathematically; they are concise summaries of observed phenomena.

Branches of Science

Natural sciences study the natural world.
Life sciences explore living organisms, including their structure, function, development, evolution, and distribution. Examples include biology, botany, and zoology.
Physical sciences investigate non-living matter and energy, including their properties, interactions, and behavior. Examples include chemistry, physics, and astronomy.
Earth sciences analyze the Earth's systems, including its composition, structure, processes, and history. Examples include geology, meteorology, and oceanography.

Scientific Methodology

The scientific method is a cyclical process that guides scientific inquiry.
It typically involves formulating a specific question, developing a testable hypothesis, designing and conducting experiments, collecting data, analyzing results, and drawing conclusions.
Hypotheses are testable statements that offer potential explanations for observed phenomena.
Experiments are designed to systematically test hypotheses by manipulating variables and controlling other factors to isolate cause-and-effect relationships.
Data collection involves recording observations and measurements meticulously. Analysis of data helps draw valid conclusions.

Measurements and Units

Accurate measurements are crucial in science, using standard units and systems of measurement to ensure clarity and comparability.
Common units include the metric system, with base units for length (meter), mass (kilogram), time (second), and others.
Significant figures in measurements denote the precision of the measurement.

Scientific Models and Theories

Models are simplified representations of complex systems or phenomena that help scientists understand and predict behaviors or outcomes.
Models range from physical prototypes to mathematical equations to computer simulations.
Scientific theories are well-supported explanations that encompass a large body of knowledge.
Theories integrate multiple hypotheses, laws, and experimental evidence to explain observed patterns and predict future behavior.
A critical element is falsifiability: a theory must be capable of being proven wrong if contrary evidence emerges.

Scientific Communication

Scientists communicate their findings through peer-reviewed publications, conferences, and presentations.
This ensures rigorous evaluation and validation of new discoveries, maintaining the integrity and trustworthiness of the scientific process.
Scientific publications follow specific formats to maintain readability, clarity, and consistency within the scientific community.
