because they need to observe what they are working on, hypothesize and predict what the outcome will be, and experiment to see if they are correct.
Scientific investigations that involve making observations typically include descriptive studies, field studies, and experiments where data is collected through sensory experiences. These investigations often focus on gathering qualitative or quantitative data to understand phenomena, identify patterns, or test hypotheses. Observations can be made in various contexts, such as ecological surveys, behavioral studies, and laboratory experiments. Overall, observation is a fundamental aspect of the scientific method that aids in forming conclusions and generating further questions.
Scientists conduct their investigations by formulating hypotheses based on observations, followed by designing experiments to test these hypotheses. They systematically collect data through observations and measurements, ensuring that their methods are reproducible and controlled. After analyzing the data, they draw conclusions and may revise their hypotheses accordingly. Finally, they share their findings with the scientific community for peer review and further validation.
Because you repeat investigation to look for errors.
They must be repeatable
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.

scientists run experiments. That is the basis of all a scientist does.
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.
As of 2021, the countries that have recently approved embryonic stem cell experiments on humans include the United States, the United Kingdom, Japan, and Sweden. These countries have regulations and guidelines in place to govern the ethical conduct of such experiments.
