Understanding Scientific Method

• Science employs a systematic and organized methodology to comprehend the natural world through observation, experimentation, and analysis.
• It requires the formulation of hypotheses, their validation through experiments, and the development of theories that elucidate and forecast natural phenomena.
• Science is empirical, hinging on evidence and data acquired through observations and experiments.
• Scientific knowledge is in constant flux, evolving as new evidence surfaces and fresh theories are proposed.
• Science is an expansive field encompassing various disciplines, including physics, chemistry, biology, and astronomy.
• Scientific inquiry necessitates critical thinking, curiosity, skepticism, and an openness to adapting explanations in light of new evidence.
• Science seeks to provide explanations for the workings of the world grounded in evidence and rational analysis.
• The scientific method serves as a process employed by scientists to probe phenomena, gain new insights, or rectify and synthesize existing knowledge.

Scientific Method

• The scientific method commonly involves observation, hypothesis formulation, experiment design and execution, data analysis, and conclusion derivation.
• Observations mark the initial step in the scientific method, wherein scientists identify patterns or phenomena in the natural world.
• A hypothesis constitutes a testable explanation for an observed phenomenon.
• Experiments are devised to assess hypotheses via the manipulation of variables and measurement of outcomes.
• Data analysis entails employing statistical techniques to interpret experimental results.
• Conclusions are formulated based on the evidence gathered from experiments and data analysis.
• Hypotheses supported by evidence may be accepted as valid explanations.
• Contradictory evidence may lead to hypothesis revision or rejection.

Branches of Science

• Natural sciences explore the physical world, encompassing biology, chemistry, physics, and earth science.
• Social sciences examine human behavior and societies, including psychology, sociology, economics, and political science.
• Formal sciences utilize formal systems to generate knowledge, including logic, mathematics, and computer science.
• Applied sciences implement scientific knowledge to address practical issues, including engineering, medicine, and agriculture.

• Quantum mechanics investigates the behavior of matter at the atomic and subatomic scales.
• Relativity explores the interrelation of space, time, gravity, and motion.

Chemistry

• Chemistry focuses on matter and its properties, along with its transformations.
• Atoms represent the fundamental constituents of matter.
• Molecules arise from the bonding of two or more atoms.
• Chemical reactions entail the rearrangement of atoms and molecules.
• Organic chemistry specializes in carbon-containing compounds.
• Inorganic chemistry deals with compounds lacking carbon.
• Biochemistry explores the chemistry of living organisms.

Biology

• Biology examines living organisms, encompassing their structure, function, growth, evolution, and distribution.
• Cells constitute the basic units of life.
• Genetics studies heredity and variation in organisms.
• Evolution denotes the process of population change in organisms over time.
• Ecology investigates the interactions between organisms and their environment.
• Botany focuses on plants.

Earth Science

• Earth science investigates the Earth and its processes, including geology, meteorology, oceanography, and astronomy.
• Geology studies the Earth's physical structure and substance, its history, and the processes acting upon it.
• Meteorology examines the atmosphere and weather patterns.
• Oceanography studies the oceans.
• Astronomy studies celestial objects and phenomena.

Scientific Theories

• A scientific theory presents a well-supported explanation of a natural world aspect, integrating facts, laws, inferences, and tested hypotheses.
• Theories possess broader scope than hypotheses and are substantiated by substantial evidence.
• Theories are not mere guesses but are founded on empirical evidence and rigorous testing.
• Scientific theories are subject to revision or rejection if contradicted by new evidence.
• Established theories include the theory of evolution, the theory of relativity, and the atomic theory.

Scientific Laws

• A scientific law constitutes a statement, based on repeated experimental observations, that describes a universe aspect.
• Laws typically manifest as mathematical equations or statements articulating variable relationships.
• Laws are generally deemed universal and invariable under specified conditions.
• Laws diverge from scientific theories, which offer broader explanations that frame the understanding of phenomena.
• Scientific laws encompass the law of gravity, the laws of thermodynamics, and the laws of motion.
