The scientific method helps scientists investigate questions systematically.

It starts with asking a question based on observation.

Next, a hypothesis is formed as a testable explanation.

Experiments are conducted to test the hypothesis.

Data is collected and analyzed during experiments.

Results are used to accept, reject, or modify the hypothesis.

Experiments should be repeatable by others.

Chemists use controls to compare results in experiments.

The scientific method ensures experiments are unbiased and accurate.

Conclusions help build scientific knowledge and understanding.
