Final answer:
The statement that experimental work includes maintaining old techniques is false, as experimental work often involves innovation. Additionally, a theory does not become a law simply due to its age, and the scientific method incorporates both creating and testing hypotheses.
Step-by-step explanation:
Experimental work in science does not necessarily include keeping old techniques, methods, or procedures for doing work; rather, it often involves improving or replacing them with new discoveries. Therefore, the statement that experimental work includes keeping the old techniques or procedures is false.
When it comes to the progression of ideas in science, the statement 'When a theory has been known for a long time, it becomes a law' is false. A scientific law and a scientific theory are two different things, regardless of how long a theory has been around. A law describes an observed phenomenon, whereas a theory explains why that phenomenon occurs.
The steps involved in the scientific method include collecting and organizing data, making a hypothesis, testing the hypothesis by experiment, and potentially rejecting the old hypothesis and making a new one if the results do not support it.
In summary, data that does not support a hypothesis is still useful because it contributes to the refinement of scientific understanding. Also, experimentation is an important component but not the only valid type of scientific investigation. The use of naturalistic observation, such as using existing records, can also provide valuable insights.
