I see no reason to....
what do your consider a law of science?
something an experiment was done for?
or could a clever fellow understand reality .....without the petri dish?
I agree that facially, it seems counter-intuitive. But, when you actually do research in the reasoning behind the agreed upon meaning of these scientific terms, it makes perfect sense. Hypothesis, theory, and law are all pieces of the scientific method. Below is a pretty good explanation of the progression. And, follow the link for a more in depth look.

In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of the phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough
empirical data and are widely accepted by the vast majority of scientists within a discipline. Both also help unify a particular field of scientific study. However, theories and laws, as well as hypotheses, are separate parts of the scientific method.
"
Hypotheses, theories and laws are rather like apples, oranges and kumquats: one cannot grow into another, no matter how much fertilizer and water are offered," according to
University of California. A hypothesis is a limited explanation of a phenomenon; a
scientific theoryis an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept, according to
Kennesaw State University.
"There are four major concepts in science: facts, hypotheses, laws, and theories," Coppinger told Live Science. "Laws are descriptions — often mathematical descriptions — of natural phenomenon; for example, Newton’s Law of Gravity or Mendel’s Law of Independent Assortment. These laws simply describe the observation. Not how or why they work."
Coppinger pointed out that the Law of Gravity was discovered by Newton in the 17th century. This law mathematically describes how two different bodies in the universe interact with each other. However, Newton’s law doesn’t explain what gravity is, or how it works. It wasn’t until three centuries later, when Albert Einstein developed the Theory of Relativity, that scientists began to understand what gravity is, and how it works.
"Newton’s law is useful to scientists in that astrophysicists can use this centuries-old law to land robots on Mars. But it doesn’t explain how gravity works, or what it is. Similarly, Mendel’s Law of Independent Assortment describes how different traits are passed from parent to offspring, not how or why it happens," Coppinger said.
Another example of the difference between a theory and a law would be the case of
Gregor Mendel. Mendel discovered that two different genetic traits would appear independently of each other in different offspring. "Yet Mendel knew nothing of DNA or chromosomes. It wasn’t until a century later that scientists discovered DNA and chromosomes — the biochemical explanation of Mendel’s laws. It was only then that scientists, such as T.H. Morgan working with fruit flies, explained the Law of Independent Assortment using the theory of chromosomal inheritance. Still today, this is the universally accepted explanation (theory) for Mendel’s Law," Coppinger said.
