Req 4h — Soils and Rocks

Nature study is not only about living things. Soil and rock shape which plants can grow, how water moves, and what habitats develop. This option helps you read the ground beneath your feet.

Requirement 4h1

Recognizing sandy soil

Sandy soil feels gritty. Water drains through it quickly, and it does not hold together well in your hand.

Recognizing clay-rich soil

Clay feels smooth and sticky when wet. It holds water longer and can be shaped or rolled more easily than sandy soil.

Recognizing humus-rich soil

Humus-rich soil is dark, crumbly, and full of decomposed organic matter. It often has an earthy smell and supports lots of life.

Requirement 4h2

Look at texture and grain

Some rocks have visible grains. Others are smooth and dense. Some break into layers, and some have crystals or holes. These details help you sort rocks into groups like igneous, sedimentary, and metamorphic.

Keep location with the rock

Where you found the rock matters. Stream rocks are often rounded by water. Road cuts may reveal local layers. Gravel piles may contain stones brought from somewhere else, so local natural sites usually make better evidence.

Use plain language if needed

If you cannot identify a rock to a very specific name, begin with what you can observe: color, grain size, hardness, layering, sparkle, or rounded edges. Careful observation is still part of good nature study.

You have now finished the menu of field-study options. The next requirement turns from observation to outdoor ethics and how Scouts should behave in natural areas.
