Well, if you want to jump higher, you need to use Newton's Third Law: if one object applies a force onto another, that object will also apply an equal force back.
Can you teach me how to jump higher?
So basically, you have to push harder into the ground. If you do this, the ground will exert more force back onto you and you will jump higher.
The boy goes to his science teacher, remembering being taught Newton's Laws of Motion. His teacher reminds him of the third law: for every action there is an equal and opposite reaction. He will use this information and try to dunk again tomorrow.

Let's do this. Just push off the ground as hard as you can, and you will dunk today.
Back so soon? Let's see what you got.
The boy is very excited for today. He feels very confident with the advice from his science teacher. Today, he will prove everyone wrong.

Oh my goodness! I did it! I dunked the basketball!
Wow! The little guy did it!
Using his newfound knowledge, the boy jumps higher than ever and dunks for the first time! He is ecstatic for proving everyone wrong. Science really does work!
