Soil is all around us. We see it in our yards, gardens, woods, streams, etc. It is a non-living natural resource...but where does soil come from? Our first grade Nature Detectives explored this question together.
First, we explored tubs of soil for clues.

Next, we went outside and collected these items. We called them our ingredients to our Soil Recipe. Can we make soil using the items we discovered in the tubs of soil?
Last, we tried mixing our ingredients to make soil. However, this did not help to change them into soil. After some discussion, we realized that we needed rain water to fall, the sun's heat to dry, worms to crawl, microbes to break down, and lots of time to eventually "decompose" these items into soil. Decomposition is the earth's way of recycling old items from nature into new, useful soil.
Our Soil Recipe
Ingredients: sticks, rocks, seeds, leaves, insects, worms, roots, old plants...
Mix ingredients outside. Add some sunshine, rain, worms, and microbes. Be patient and wait a long time for ingredients to "decompose" into soil.
