Explanation

This 'lesson' should help you 'to understand' how the 'use' of scientific method has improved living 'conditions'. The phrase "to understand" is used correctly.

About Prepositions

Prepositions link a noun or pronoun to the rest of the sentence, showing place, time, direction or relation. The difficulty is idiomatic rather than logical: English fixes particular prepositions to particular verbs and adjectives, so “good at,” “married to” and “differ from” have to be learned as units rather than reasoned out.
