Project Idea
Often, when we think of something that is solid we think about rocks. But in reality, rocks have tiny holes of air inside them. This is called porosity. In this science project you can find out what it means to be "solid as a rock!" Read more

thumbnail This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and cave formation. With your model system, you can simulate various underground conditions, and test your predictions about the effects they have on water flow. Read more

thumbnail When an earthquake happens, how are scientists able to determine the original location of the quake? In this project, you'll use archived data from a global network of seismometers to find out for yourself. You will make your own seismograms using the Global Earthquake Explorer program, and then use the seismograms to determine the location of earthquake epicenters. Read more

thumbnail When an earthquake occurs, seismic shock waves travel out through the earth from the source of the event. The shock waves travel through the earth or along the Earth's surface, and can be recorded at remote monitoring stations. Some of the waves that travel through the earth are blocked or refracted by the Earth's liquid core, which means that monitoring stations located certain distances from the earthquake do not detect these waves. This creates a "seismic shadow" that you can use to… Read more

Time Required Long (2-4 weeks)
Prerequisites This project uses the Global Earthquake Explorer program to download and analyze data from a global seismic network. In order to do this project you will need to be comfortable installing and working with a new program on your computer. This project requires a computer with high speed Internet access. You will also need to understand some basic trigonometry. You should be comfortable with determining the lengths of the sides of right triangles when given an angle and the length of one side. Experience looking at seismograms is useful but not required.

thumbnail What do rocks and clocks have in common? Both keep track of time. Yes, radioactive isotopes present in rocks and other ancient material decay atom by atom at a steady rate, much as clocks tick time away. Geologists use those radioactive isotopes to date volcanic ash or granite formations like the giant Half Dome in Yosemite National Park. Anthropologists, archeologists, and paleontologists also use radioactive isotopes to date mummies, pottery, and dinosaur fossils. Does this sound abstract… Read more

Project Idea
Did you know that waves travel through the Earth’s crust all the time? One major source of these waves is earthquakes, although ground motion can also be caused by something man-made, such as a mine blast or nuclear explosion, or other natural events, such as landslides or volcanic activity. How does an earthquake cause these waves? The entire outer shell of the Earth, known as the lithosphere, is made up of tectonic plates that are constantly moving. There are seven or eight large… Read more

Project Idea
thumbnail Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment.In this geology science project, you… Read more

thumbnail When an earthquake happens, how are scientists able to determine the original location of the quake? In this project, you'll use archived data from a network of seismometers to find out for yourself. You'll create your own seismograms from the comfort of your own computer with an easy-to-use webpage interface. Then you'll analyze your seismograms to determine the distance of the quake from each seismometer station. By mapping your analyzed data, you will be able to determine the location of the… Read more
