What is the difference between "Award" and "Reward"?

Award: Prize, like a certificate 或者 trophy, something material that is 更多 for recognition, but could come with something like money.
Reward: Prize, but something 你 want, like 饼干 或者 time off work, something 你 deserve.

Reward is 你 get something good in return for doing something good... and an award is, 你 know, an award.

Sorry if i explained this badly lol

Award: When 你 win an award
Reward: When 你 rewin an award
I really don´t know...
