Science Buddies: "Ask an Expert"

Hello,
I had been asked by my science teacher to realize this experiment in your website called "Can you predict a spatter?".
My questions is : Testing the effect of _______________________ on ________________________.
and What am I measuring in this experiment.

Thank you so much.

This experiment seems to be about measuring the location of the source of a splatter by measuring characteristics of the ellipses of the splatters. So you could say that it is "testing the effect of source location on the shapes of splatters".

Hello again,
So my Independent variable is : The number of teaspoons in the 5 trials.
and my
Dependent variable is: The location of the source of a splatter .
Please, can you explain me if I'm wrong, Thank you. ( This experiment its's supposed to be a cause and effect).
Thank you again.
