They must be repeatable
Ask questions.
scientists run experiments. That is the basis of all a scientist does.
In order for an experiment to be considered ethical, and in some cases legal, it must be approved by a governing body. Often, this body is a research institution like a school, but sometimes the approval has to come from higher up.
Investigations and experiments are related because they are exercises that help find a solution to a problem.
There are lots of different kinds of scientific investigations, all of which help people learn different things. However, two of the most common investigations are experiments and fieldwork. Experiments involve creating a hypothesis and designing a procedure by which to test it. Fieldwork involves going into the larger world with a hypothesis in mind and observing nature or people to prove that hypothesis.
Many branches of science do not lend themselves to experiments. Cosmology or astrophysics are subjects where it is extremely difficult to conduct experiments. Theories are developed though thought experiments which are then used to make testable predictions. It is only at the later stage that experiments enter the picture.

Investigations involving charged particles, and bombardment of targets with them.

The scientist must propose an idea and document it with experiments that prove it. The experiments must be repeatable by others and the same result must be obtained by them
