Today Mrs. Fleener took us and Mr. Gibson's class outside to discover different types of soils.  We found the differences between four types of soil.  There is clay, gravel, sand, and humus.  First was gravel.  We felt it and it felt hard, rough, and sratchy.  Next was the clay.  It felt very soft, dry, smooth and powdery.  Next came the humus.  We were surprised that it felt spongy.  It had decaying leaves in it.  I think the part I touched was decaying bone because it was very hard like a rock.  When we were finished, we cam in to write this paragraph.
