My definition is below:

"Science is the human endeavor to understand how the physical universe
works by constructing testable cause-and-effect natural explanations of
events and processes based on observations of the physical world."

This describes geological science as well as chemistry. As I have
argued several times on this forum and elsewhere, hypotheses in the
historical sciences are fully testable. What I do as a geologist is
continual hypothesis testing. Every new observation is a test of
expectations based on previous observations and theoretical
understanding. Hypothesis are accepted, modified or rejected based on
new observations (equivalent to new experimental trials).
