Working with particle effect

Hey Everyone,

I am trying to create an effect where my game object hits the ground, a small boom is heard, and you see little particles (dust or dirt) jump from the floor then fall again quickly. Just like when Hulk jumps to the ground and you see rubble jump up from the impact.

Particle systems are completely new to me and I have not had any luck in a few hours or playing with it. Do any of you know how to accomplish such a thing?

Thanks for all your help.

Cheers.
