Science is a systematic study of the natural world.
Science relies on observation, experimentation, and analysis to build knowledge.
Science aims to develop testable explanations and make predictions about the natural world.

Physical sciences study the fundamental laws governing matter, energy, and their interactions.
- Physics investigates the properties of matter and energy.
- Chemistry examines the composition, structure, properties, and reactions of substances.
- Astronomy focuses on celestial objects and the universe.
Life sciences explore living organisms and life processes.
- Biology investigates the structure, function, growth, origin, evolution, and distribution of living organisms.
- Ecology examines the interactions between organisms and their environment.
- Genetics studies heredity and how traits are passed from parents to offspring.
Earth sciences study the Earth's structure, materials, and processes.
- Geology investigates the Earth's composition, structure, history, and processes.
- Meteorology studies the atmosphere, weather patterns, and climate.
- Oceanography investigates oceans, marine life, and oceanographic processes.

The scientific method is a systematic approach to investigating phenomena.
It starts with an observation, leading to a question about the observed phenomenon.
A hypothesis is formulated, a testable explanation for the observation.
Experiments are conducted to gather data relevant to the hypothesis.
The data is analyzed to support or refute the hypothesis.
A conclusion is reached, summarizing the findings and their implications.

Science is vital for technological advancements and medical innovations.
Science plays a crucial role in addressing global challenges such as climate change.
Science enhances our understanding of natural phenomena, contributing to a more informed society.
Science fosters critical thinking and problem-solving skills, essential for navigating complex issues.

A theory is a well-substantiated explanation of an aspect of the natural world, supported by a vast body of evidence.
A law is a statement based on repeated experimental observations describing an observable phenomenon.
A variable is any factor that can change in an experiment.
- An independent variable is manipulated by the researcher.
- A dependent variable is measured in response to changes in the independent variable.

Integrity and honesty are paramount in scientific research.
Peer review and reproducibility are essential for ensuring the credibility of scientific findings.
Ethical considerations must be addressed in all aspects of scientific research, particularly in experimentation involving human subjects or animals.

Laboratory equipment like microscopes, spectrometers, and centrifuges facilitate scientific investigations.
Field studies allow scientists to observe and collect data in natural settings.
Data analysis software, such as Excel and R, is used to analyze and visualize data gathered during experiments.

Biotechnology is revolutionizing medicine and agriculture through innovations in genetic engineering and CRISPR technology.
Astrobiology explores the potential for life beyond Earth, sparking curiosity about the origins and evolution of life.
Quantum computing is a rapidly developing field that has the potential to revolutionize computing and scientific research.
