Science

Systematic study of the natural world through observation and experimentation.

Basic Concepts

Observation and Experimentation

Looking and Testing

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.

Observation

Scientists carefully watch, measure, and record details, sometimes using tools like microscopes or telescopes.

Experimentation

Experiments are planned tests. By changing one thing at a time, scientists see how it affects results.

Recording Results

Data is collected and often shown in charts, tables, or graphs to make patterns easy to spot.

Why is this Important?

These steps make sure findings are accurate and can be repeated by others.

Examples

  • Observing how sugar dissolves in water.

  • Experimenting to see which type of paper airplane flies farthest.

In a Nutshell

Scientists observe and experiment to learn about the world.
