Ways to tell them apart:
Lessen means to make something less, as in reducing it in size, amount, or intensity.
Lesson refers to a period of learning or teaching, often a part of educational instruction.

Both words sound the same, but lessen relates to quantities, and lesson relates to educational topics.
