Erosion in a Bottle
Soil erosion is the process of moving soil by water or wind — this happens naturally or through human interference. Preventing soil erosion is important because nutrients are lost, and sediment that accumulates in waterways impacts life there. Conserving soil depends on how it is protected by plants and coverings.
You will model erosion by water and compare the amounts of runoff and soil loss generated from three different ground cover types.

Grow Your Own Crystals
Most minerals happen naturally as crystals. Crystals are made of specific atoms or molecules joined to make distinctive repeating patterns. The crystals that make up many kinds
of minerals are formed deep underground through the interaction of fluid, pressure, and temperature. Some minerals form at or near the surface. You may have seen spectacular mineral samples in museums, but you might not be aware that minerals are everywhere, including in your body.

In the water cycle, there are two ways water moves from the ground to the atmosphere: evaporation and transpiration. During evaporation, water changes from a liquid to a gas state. Transpiration is basically evaporation of water from plant leaves. Transpiration accounts for about 10 percent of the moisture in the atmosphere — with oceans, seas, and other bodies of water providing nearly all the rest.
Mining Creates Reservoirs and Habitats
There is an important interconnection between local mines and quarries that later become reservoirs and supply crucial water resources to local communities. The life cycle of a mine has different phases. Production supplies important resources such as construction materials and other important minerals. Then with the mine’s closure and reclamation, it is sometimes used for freshwater
storage and supply for the local community. Another part of a quarry’s life cycle can be to offer new habitats and support biodiversity.
