We are learning about soil! There are layers of soil that make up what's called the soil horizon.
The first layer is HUMUS. It's all the dead stuff on top, the mulch. That includes dead leaves, dead insects, twigs and bark.
The layer below humus is LOAM. It's the really dark, nutrient rich soil. It's a mixture of everything: a mixture of Loam, sand and clay.
The next layer is SAND and CLAY.
Bedrock is below that. Bedrock is apart of the earth's crust. It's the rock that all the soil sits on.
Here are lyrics to a rap we wrote during tutoring yesterday:
HUMUS is the mulch on the top.
You might be out of breath, but don't stop!
LOAM is a mixture of dead stuff and clay.
The bits of SAND and CLAY sit on bedrock, hey!
Here's the music video of that rap! Check it out! Way to go Alexandra, Amaris, Matteo, and Caroline!
