Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process.
Maintaining Soil Moisture
Soil is a vital component of almost every ecosystem, and its health often determines the viability of the whole ecosystem. If a soil cannot support the living organisms within it – such as insects, bacteria, fungi, and plant roots – then it is likely that the entire ecosystem will suffer. The same is true on farms. The success of crops is dependent on the health of the soil.

Solar Updraft Tower
Electricity is the most common type of energy used around the world to power homes and businesses. Traditionally, electricity is generated in power plants that burn coal or oil. These resources have been used at a rapid rate and also give off greenhouse gases, which have contributed to global climate change.
Sources of Minerals
We are surrounded by objects that we depend upon for our everyday lives. From our clothes to our phones, bikes, cars, showers, plates, chairs, televisions, computers, and nearly everything else, we rely on objects made of a variety of materials. But where do those materials come from in the first place, and what happens when we run out of them?
Sustaining Living Soil with Composting
Composting is the decomposition of organic waste materials in the presence of water, air, and microorganisms to produce organic fertilizer. Organic matter improves soil quality by feeding soil organisms, provides plants nutrients for growth, and enhances soil structure and water holding capacity., while reducing our dependence on synthetic fertilizers.
Wetland in a Water Bottle
Wetlands are places where the water table is usually at or near the surface or the land is covered by water or saturated at least some of the time. They include mangroves, marshes, swamps, forested wetlands, and bogs and are important nurseries for young birds, fish, amphibians, and other aquatic plants and animals. In addition to providing habitat for wildlife, wetlands offer storm protection, improve water quality, support aquatic species, and provide recreational opportunities.
