Water that you should not absorb let her run
by VLP_Agency
As Violeta looked at her plot, she noticed that the soil at the top of the mound was lighter in color than the soil at the bottom and flattest part. Without thinking much about it, she touched the soil in both places and noticed that the one at the top was dry and the one at the bottom was wet.
This discovery caught his attention and, without digging too much into his memory, he recalled that in a documentary that Professor Salvatierra showed them in class, he learned that gravity is the force that attracts all objects to the surface of the Earth, that is, which makes all things stick to the ground. Anxiety arose immediately.

Why is the soil at the top of the plot dry and the soil at the bottom wet? Could it be that the inclination and gravity cause the water to slip off and that the soil of the upper part cannot absorb it, accumulating in the lower part of the mound?
Violeta and the bird Rara, fascinated with the mystery to be discovered, thought of a way to respond to this concern and designed the following experiment:
Question:
What amount of water exceeds and is not absorbed by the soil contained in three trays that have different slopes or slopes?
* What is measured? The amount of water exceeded and not absorbed by the earth.
* What is compared? Three different slopes (high slope, medium slope and zero slope).
