What are the five requirements for scientific investigation?
The scientific method has five basic steps, plus one feedback step:
- Make an observation.
- Ask a question.

Do scientists always follow the scientific method?

- Identify the problem. The first step in the scientific method is to identify and analyze a problem.
- Form a hypothesis.
- Test the hypothesis by conducting an experiment.
- Analyze the data.
- Communicate the results.
What are science experiments, investigations and activities?
Science experiments, investigations and activities may involve the use of a range of laboratory equipment (e.g. glassware, heating equipment), digital equipment and physical, chemical and/or biological materials. Science experiments, investigations and activities may involve other activities that have various risk levels.
Why do scientists want to do an investigation?
Investigations in science. Scientists conduct investigations for all kinds of reasons. They may want to explore new ideas, gather evidence or prove or disprove previous results. Although scientists must follow certain methods to ensure their results are fair and accurate, there are many ways they can conduct an investigation.
