How it works · 6 phases
Step by step.
- Make an observation and ask a question about a natural phenomenon.
- Research existing information and form a testable hypothesis.
- Design and conduct a controlled experiment with independent, dependent, and controlled variables.
- Collect and analyze data from the experiment.
- Draw conclusions about whether the data supports or refutes the hypothesis.
- Communicate results and allow others to replicate the experiment.
