Clay, Sand, Humus, OH MY!


Today in our Soil Kit we investigated what happens when you add water to clay, sand, and humus?  Will the components of soil retain their shape or will they distance themselves?  Will they be able to hold together to form a ball and roll?  We discovered that clay was the only soil component that would roll into a ball.  We discussed why and talked about the particles of clay vs. the particles in humus and sand.  Next up, we try to streak clay, sand, and humus!
