Here's a breakdown:

* Hypothesis: A proposed explanation for a phenomenon that can be tested through observation and experimentation.

* Experiment: A controlled procedure designed to gather data and test the hypothesis.

By conducting an experiment, scientists aim to:

* Gather evidence: Support or refute the hypothesis.

* Gain understanding: Learn more about the phenomenon being studied.

* Advance knowledge: Contribute to the scientific understanding of the world.

* Solve problems: Develop solutions to real-world issues.

Ultimately, the goal of science is to seek knowledge and understanding through observation and experimentation. Experiments are the tools scientists use to achieve these goals.
