What is an investigation?

An investigation is a gathering of information we might want to do an experiment on. It is also the collection of data for information that does not require a hypothesis or prediction.

For example, if you want to see how tall a sunflower plant grows in a month. You may read books on sunflowers or visit websites with sunflower information. You would be conducting an investigation to collect data. This can be the background research step of an experiment.
