Difference Between Lesson and Chapter

Key Difference: Lesson and Chapter in academic life like in school, both the words are used interchangeably like for example:

  1. Open your books, we will study the next lesson.

  1. My experience taught that it is better to stay honest and true than to lie. (This is experience teaching a person a life lesson.)

  2. Today in Science, we will do Anatomy and will cover Human Anatomy today. (This sentence explains that the teacher is teaching Science as a subject, with Chapter name as Anatomy in that the subsection topic or lesson as Human Anatomy.)

Whereas, Chapter is more or less like a division of a relative length or to signify milestone of a story or in life. For example:

  1. I reached a new chapter in my life.

  2. I am on the 4th chapter.
