! SOIL ! SHAKES !

In school we learned about soil shakes and what they are.
It's soil that is in water and before it settles you have to shake them.In a hour or two it makes layers of soil,
water and sediments. We used three different types of soil to see the differences. The different types of layers are gravel,sand,silt and clay. It's kind of cool because organic matter floats on top.

!IT WAS SO MUCH FUN!
