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.
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 Around the World
Scientists need your help. Those studying Mars are asking students from around the world to help them understand "the red planet." Send in a rock collected by you or your classroom from your region of the world, and NASA scientists will use a special tool like the one on the Mars Rover to tell you what it's made of. Then everyone can compare their rocks to the ones found on Mars.
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
ShakeAlert Earthquake Early Warning
Have you ever felt an earthquake? What was it like? Where were you? What did you do? More than 143 million people are exposed to potentially damaging shaking in the United States.
Splish Splash
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? What path did this water follow in order to become our drinking water? This lesson will explore the hydrologic cycle and water's journey to our glass.
Step by Step Weather Observations
As a citizen scientist, you can take your own air temperatures with an outdoor thermometer and compare your readings to the official ones from the National Weather Service. It is important that you follow the correct procedures, however, for placing your thermometer. This activity will help you to do that, as well as find out what the normal yearly average temperature is for each day.
Third From the Sun
In 1972, NASA launched a special satellite called Landsat that contained a new camera designed to take pictures of the Earth. Why was this satellite so incredible? Well, it could take a series of pictures of almost the entire Earth over and over again, season after season, month after month, year after year. You will be seeing Landsat images in this activity and learn how to interpret them.
Using Energy Resources Wisely
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?
Water Filtration
Each group will design a water filtration system and present to the class, why they picked their design.
