Solar Updraft Tower Activity Source: American Association of Petroleum Geologists. Adapted with permission. 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. Alternative sources of energy, such as solar, wind, and geothermal, are renewable energies that do not lead to an increase in greenhouse gases and are therefore more sustainable. [Read More]

Solution Mining for Uranium Activity Source: Minerals Education Coalition Grade Levels: 7-12 Background Nuclear energy is used around the world to generate electrical power in a way that does not produce greenhouse gases. Its use is predicted to grow in the coming years. This will increase the demand for uranium, which is mined for medical, industrial, and defense purposes, in addition to producing nuclear energy. Although it is mined in several ways, most uranium in the U. [Read More]

The Potential of Energy Reservoirs and Deposits Activity Source: American Association of Petroleum Geologists Grade Levels: 6-12 Background All countries rely on multiple energy sources to power industries, homes, and transportation. The combination of energy sources used by a nation is called their energy mix. Energy comes in many forms, and some of the most important sources are stored beneath the Earth’s surface (known as reservoirs). Each of these sources plays a critical role in generating electricity around the world. [Read More]

Traveling Nitrogen Activity Source: Windows to the Universe. Adapted with permission. Nitrogen is an element that is found both in living things and the nonliving parts of the Earth system. In this classroom activity, students play the role of nitrogen atoms traveling through the nitrogen cycle to gain understanding of the varied pathways through the cycle and how nitrogen is relevant to living things. For the teacher: To prepare, set up nitrogen reservoir stations around the classroom (or outside). [Read More]
