I Need You!
Ode to Soil
Roses are red,
and soil is brown.
Just what is this
stuff
that covers the ground?
Why is it that
we think of soil
in a negative way?
When without soil,
we wouldn't be here today.
Yes, roses are red, they grow because of the dirt.
So do daisies, pine trees, and even the cotton, that makes your shirt!
Maybe it is time to appreciate the soil - let's start today.
Yes, roses are red, and many other colors as well.
And now you know that soil is sure swell!
Okay, I know what you are thinking. That was a really bad poem!
Hey, when is the last time you tried using your writing skills to make up a poem about soil? The truth is, that most of us don't think about soil as the subject for poems or plays.
But have you really taken any time to think about soil ? If it was not for soil, plants would be unable to grow. Now...where would we be then?
Try it!
Materials:
- Sand
- Water
Procedure:
- Pile up the sand as tall as you can.
- Slowly pour water on one side of your sand pile. Observe what happens.
- Increase the pouring speed of the water and see what changes.
- Try building a different sand pile design. Then vary how you pour the water.
Analysis:
- How did the experiment model erosion as it happens on Earth?
- What differences did you see when you changed the sand pile design or changed how you poured the water?
