The ocean is a “carbon sink,” which means that it removes CO2 (carbon dioxide) from the atmosphere. The ocean currently absorbs about one-third of the CO2 released by the burning of fossil fuels.
However, beyond a certain level of atmospheric CO2, the ocean can no longer act as a carbon sink without it having a negative impact on marine life. When CO2 dissolves in seawater, it leads to decreased pH levels. The ocean becomes less alkaline. This is referred to as ocean acidification.
In this activity, students will learn the pattern of major ocean currents and how they are changed by wind, land and water.
Discuss how a 3-D model illustrates the geology of oil deposits. What challenges do you think petroleum geologists must overcome to recover oil?
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. Soil colors serve as pigments in bricks, pottery and artwork. The color and texture of soil painting is fascinating and a creative opportunity for all ages of students.
What factors affect how easily a fluid can move through sediments? How is this flow rate connected to oil production? In this investigation, you will explore the permeabilities of different materials. You will then use your observations to determine what affects permeability and how this might relate to oil production.
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.
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?
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.
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.
When it rains, much of the water drains directly into the ground. But why?
