Layers of Soil

Instead of Halloween treats this year, we celebrated soil by eating our delicious stone soup.  Thank you to everyone for contributing and participating!

We also reviewed the 3 layers of soil with a food craft.

3 Layers of Soil

The bottom layer is bedrock - made with mini marshmallows to represent the large boulders that make up bedrock.

The middle layer of soil is subsoil - made with Cheerios to represent medium sized rocks with space for air and water between them.

The top layer of soil is topsoil - made with Rice Krispies to represent the smallest sized rocks, mixed with Smarties to represent the brown humus.

Again the soil was topped off with an earthworm - made with a gummy worm.

Yum!!!
