Soils

During our "What's Your Part" IB unit, we learn about the components of our earth - soils! Today we talked about the different parts that make up the topsoil and subsoil - humus, clay, and sand. We used our *4* senses to observe the three soils and took notes in our science journals. Then, we did a wet test to see if the different soils could be rolled into a ball - what a mess! The kids loved experimenting and gained new knowledge about the makeup of our earth.
