Final answer:
Science is a way of understanding the physical world based on observable evidence, reasoning, and repeated testing. Scientists follow a scientific method that involves observing natural phenomena, proposing hypotheses, designing experiments, collecting data, and analyzing results. Science can study things that are observable and measurable, while things that cannot be observed, such as supernatural beings or events, are outside the bounds of scientific inquiry.
Step-by-step explanation:
Science is a way of understanding the physical world based on observable evidence, reasoning, and repeated testing.

Science can study things that are observable and measurable, while things that cannot be observed, such as supernatural beings or events, are outside the bounds of scientific inquiry.
For example, a biologist could study the effect of different fertilizers on plant growth by designing an experiment and measuring the height and health of the plants. This study falls within the realm of biology because it involves a living organism and can be observed and measured.
In contrast, something like morality or spirituality cannot be studied scientifically because they are outside the realm of material phenomena and cannot be observed or measured.
