Science

Science is the systematic study of the natural world through observation, experimentation, and reasoning. It aims to understand how things work, explain natural phenomena, and make predictions based on evidence.

Key features of science:
• Observation – noticing and describing events or processes in a careful, orderly way.
• Hypothesis – proposing explanations based on what is observed.
• Experimentation – testing hypotheses under controlled conditions.
• Analysis – examining data to draw conclusions.
• Theory – a well-tested explanation that unifies many observations and experiments.

Main branches of science:
1. Physical science – study of non-living systems (e.g., physics, chemistry).
2. Life science (biology) – study of living organisms.
3. Earth and space science – study of Earth, the atmosphere, and the universe.
