Ocean Currents Change Our Earth Activity Source: NASA. Adapted with permission. Ocean currents — the continuous, directed movement of ocean water — affect regional climates and alter the biological and chemical characteristics of seawater. Currents can flow for long distances both at and below the ocean’s surface. Wind drives surface currents, whereas density often drives deep ocean currents. Density, a physical property of matter, is mass per volume. Density is not simply weight — it depends on the volume of the sample (the amount of space the sample occupies). [Read More]

Oil Trap Model Activity Source: Geological Society of America. Adapted with permission. Crude oil is a liquid hydrocarbon that is thought to have formed from the accumulation and burial of mostly marine organisms in a low-oxygen environment. This environment prevents decay of the organisms, trapping the organic matter and converting it to hydrocarbons. Because oil is a liquid that is lighter than water, it naturally rises through the pores of rocks in which it forms towards the surface. [Read More]

Painting With Soil Activity Source: Soil Science Society of America, Adapted with permission Soils are one of our most important natural resources — just think of where all the food you eat comes from. They also are important for the beauty the many soil colors add to our landscapes. Most of us overlook this natural beauty because we see it every day. Often these colors blend with vegetation, sky, water, etc. [Read More]

Parks Past, Present, and Future Activity Source: Adapted with permission by National Park Service. Over Earth’s 4.5 billion-year history, tectonic upheavals and colliding plates formed mountain ranges and carved out basins. Forces of erosion and weathering have been at work to break down these landforms. Records of these processes are imprinted on the land and define distinctive landscapes around the United States and in its national parks. The dynamic processes that formed the spectacular landscapes of many national parks remain active today. [Read More]

Particle Size and Oil Production Activity Source: Adapted by AAPG from EarthComm and the American Geosciences Institute. Adapted with permission. What factors affect how easily a fluid can move through sediments? How is this flow rate connected to oil production? Many people think that oil lies in big pools below Earth’s surface. Oil actually is located in the pores within rocks (called “source rocks”). When the pores are connected, oil can flow slowly through the rock. [Read More]

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.

Plant an Ozone Monitoring Garden Activity Source: Adapted with permission from NASA Aura Education and Public Outreach. To measure ozone in the Earth’s atmosphere, NASA built the approximately 6,500-pound Aura satellite. The spacecraft carries four high-tech instruments that scan the globe from more than 700 kilometers above the planet. For students, there is an easy way to investigate ozone in their own neighborhood. It’s as simple as growing a few carefully selected plants. [Read More]

Predict the Flow Activity Source: NASA and AGI. Adapted with permission for the American Geophysical Union. Ever play with clay? Using a common modeling compound, you can form a “volcano” and examine its topography to predict which way lava will flow down its slopes. You could also investigate mud flows or debris flows. Materials 2 containers of modeling compound or clay Clear plastic bin Dark colored water (make sure that your modeling compound is a contrasting color from your water) Clear clipboard 2 transparencies and transparency marker Safety scissors Dish detergent Baking soda Vinegar Dropper Metric ruler Tiny plastic cup (about 2 oz.

Products from Petroleum Activity Source: Society of Petroleum Engineers. Adapted with permission. Where would we be without petroleum? You can kiss lipstick goodbye! Not only does petroleum provide fuel to run our vehicles, cook our food, heat our homes, and generate electricity, it is also used in plastics, medicines, food items, and countless other products, from aspirin to umbrellas and, yes — lipstick! We use many oil products as synthetic alternatives to natural materials, including synthetic rubber instead of natural rubber, and detergent instead of soap. [Read More]

Products Made from Petroleum Activity Source: Adapted with permission by Bruce Wells, American Oil & Gas Historical Society. Background Most people associate petroleum with transportation — but we are surrounded by thousands of other everyday products that come from this vital natural resource. A typical 42- gallon barrel of crude oil yields about 20 gallons of gasoline and 4 gallons of jet fuel. What products come from the other 18 gallons? [Read More]
