Systematic study of the natural world through observation and experimentation.
Observation and experimentation are the heart of science. Observation means using your senses to notice details about the world. Experimentation involves testing ideas in controlled ways.
Scientists carefully watch, measure, and record details, sometimes using tools like microscopes or telescopes.
Experiments are planned tests. By changing one thing at a time, scientists see how it affects results.
Data is collected and often shown in charts, tables, or graphs to make patterns easy to spot.
These steps make sure findings are accurate and can be repeated by others.
