Places on the Planet: Latitude and Longitude Activity Source: Geological Society of America, 2006. Adapted with permission. Background You may have seen or used Global Positioning System (GPS) devices in cars or on camping trips. These devices use data from satellites orbiting the Earth to locate places on our planet. GPS devices describe the locations to us in the form of latitude and longitude coordinates. Citizen scientists involved in the Geological Society of America’s EarthCaching project (http://www.

Properties of Fluids in Reservoirs Activity Source: American Association of Petroleum Geologists. Adapted with permission from EarthComm , American Geosciences Institute. Petroleum geologists play a vital role in locating energy resources. They use a variety of methods to collect the data they need to find reservoirs of oil and natural gas. When they find these reservoirs, petroleum geologists need to calculate their volume. They also need to estimate how much they can recover (remove) from the reservoir. [Read More]

Properties of Fresh Water and Sea Water

Rain and Soil Activity Source: Adapted with permission by Soil Science Society of America. When it rains, much of the water drains directly into the ground. But why? Soil is made up of four main components: minerals, organic matter, water, and air. Ideal percentages of each is shown in the figure, but in reality the percentages vary from location to location. Water moves through open spaces in soil known as “pores. [Read More]

Sea and Ice Salinity Activity Source: NASA Aquarius Mission and the National Snow and Ice Data Center, 2007. Activity adapted with permission from UCLA Marine Science Center’s OceanGLOBE. Background What is sea ice? It is simply frozen ocean water. Why is sea ice important? While it occurs mainly in polar regions, sea ice influences our global climate. Changing amounts of sea ice can affect ocean circulations, weather patterns, and temperatures around the world. [Read More]

Soil Moisture Activity Source: Soil Science Society of America Soil moisture is the water stored in the soil and is affected by precipitation, temperature, soil characteristics, and more. These same factors help determine the type of biome present, and the suitability of land for growing crops. The health of our crops relies upon an adequate supply of moisture and soil nutrients, among other things. As moisture availability declines, the normal function and growth of plants are disrupted, and crop yields are reduced. [Read More]

Splish Splash Activity Source: National Geographic Expeditions Overview Crucial to our existence, water sustains all life on Earth. Following the old adage, “What goes around comes around,” water moves continuously through the stages of the hydrologic cycle (evaporation, condensation, and precipitation). How does our drinking water fit into this hydrologic cycle? Where did the water we drink fall as precipitation? Did this water percolate down into the ground as part of a groundwater system, or did it remain on the surface as part of a surface water system? [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]

Using Energy Resources Wisely Activity Source: American Association of Petroleum Geologists. Adapted with permission. People depend on their energy resources, so they need to know how to use them wisely. How do you think people can use the energy they rely on to heat their homes more efficiently? Materials Plastic cup, foam cup, and metal soup can, all around the same size Plastic wrap and sheets of paper Masking tape Supply of warm water 3 alcohol thermometers Measuring cup Calculator and notebook Graph paper Watch or clock Procedure Predict which item - plastic cup, metal soup can, or foam cup - will keep water warm the longest.

Visualizing Your Watershed Activity Source: Source: American Geophysical Union. Adapted with permission. Watersheds can be as small as a lake or thousands of square miles. The natural or human-made surface of the land and the sediments and rocks below are all part of a watershed. Rainfall supplies watersheds, and water moves across the surface or infiltrates and moves through the ground. In this activity you will use a computer model to explore the movement of water within your watershed. [Read More]
