Products Made from Petroleum

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?

Properties of Fluids in Reservoirs

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. This helps them to determine the possible value of the discovery. By using a model, this investigation will help you to understand the physical relationships between natural gas, oil, and water in a reservoir and how these relationships can affect recovery.

Properties of Fresh Water and Sea Water

The students will set up three demonstrations to observe the properties of water. They will explore the boiling point of water, the freezing point of water, and the ability of water to store heat. These activities can be done individually or as a set.

Rain and Soil

When it rains, much of the water drains directly into the ground. But why?

Rock Abrasion

Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off. In this activity, you will model how abrasion works.

Rock Pop

How can a cave form from solid rock? Most caves are found in limestone, a rock made of materials of calcium carbonate.  This rock is unusual because the solid minerals it is made of easily dissolve in weak acids.  The most common weak acid in the environment is actually water!

Sea and Ice Salinity

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. Sea ice insulates the relatively warm ocean water from the cold polar atmosphere, except where cracks in the ice allow for the exchange of heat and moisture. The exchange of salt between sea ice and the ocean alters the density of ocean waters, thus influencing ocean circulation. Many animals, such as polar bears, seals, and walruses, depend on sea ice for their habitat. These species hunt, feed, and breed on the ice. Satellites provide the best way to observe sea ice, the factors that affect sea ice, and the ways sea ice affects global climate. Scheduled to launch in 2010, NASA’s Aquarius mission will measure global sea surface salinity with unprecedented resolution. Even small variations in sea surface salinity — the amount of salt present near the ocean’s surface — can have dramatic effects on sea ice, the water cycle, and ocean circulation.

Sea Level and the Terrapin

This activity from the Environmental Protection Agency will give children the opportunity to see how changes in sea level effect coastlines, animal life, and community development.

Seismic Calendar

This activity allows you to investigate how often earthquakes of various magnitudes happen within a geographic region of your choice. You will use the online resources of the Incorporated Research Institutions for Seismology (IRIS) to do the investigation. These resources are available at http://www.iris.edu

Shoebox Geologist

Earth processes such as volcanic eruptions, floods, landslides, and glaciers leave behind evidence of their passing in the form of layers known as deposits. By studying deposits of recent geologic events, geologists are able to better understand older deposits and identify the processes that caused them.
