How Old Is That Rock? Roll the Dice & Use Radiometric Dating to Find Out
Science Fair Project Idea
Scientific Method
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 and… Read more
Is There a Whole Lot of Shaking Going On? Make Your Own Seismograph and Find Out!
Science Fair Project Idea
Engineering Design Process
If you live in an area where earthquakes happen, you might be especially interested in this science project. You will learn how to build your own seismograph and how to use it to detect ground motion. Read more
Locating the Epicenter of an Earthquake
Science Fair Project Idea
Scientific Method
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
Pop Goes the Geyser!
Science Fair Project Idea
Scientific Method
Our home, Earth, is a living planet. Earthquakes and volcanic eruptions are proof that the geological forces that shaped our planet and created the land masses are ongoing. An amazing example of geologic activity that is less damaging is a geyser. In this geology science fair project, you will build a model geyser and determine how depth of the source affects how the water is ejected. By the end of this project, you will know a lot more about geysers and understand that a geyser is much more… Read more
Ring of Fire 1: What Volcanoes Tell Us About Plate Tectonics
Science Fair Project Idea
Scientific Method
The Ring of Fire is a region of volcanic and earthquake activity that surrounds the Pacific Ocean. In this project you can explore the connection between plate tectonics and volcanic activity by mapping historical data. Read more
Ring of Fire 2: What Earthquakes Tell Us About Plate Tectonics
Science Fair Project Idea
Scientific Method
Today it is widely accepted that the Earth's crust consists of a series of huge plates that slowly move. The low parts of the plates are beneath the world's oceans, and the high parts of the plates are landmasses. New plate material is generated at deep sea ocean ridges in a process called sea-floor spreading. Material from plates is also recycled at trenches, where dense, oceanic crust dives back (subducts) underneath an adjacent plate towards the upper mantle. Figure 1 shows a map of the… Read more
Soil Structure
Science Fair Project Idea
Scientific Method
What variables contribute to the properties of the soil in an area? Investigate the role of climate, weather, topography, time, parent material, vegetation, and biological and chemical agents on soil formation. How are soils characterized? There are 3 basic particle sizes which create three basic soil types: sand, silt, and clay. Investigate the properties of the three different types of soil by observing grain size, shape, hardness, color, chemical composition, pore space, aeration,… Read more
Sorting Out Sedimentation
Science Fair Project Idea
Scientific Method
Sedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. How do sediments form? How are sediments of different shapes, sizes, and types sorted during the process of sedimentation? Find out in this science fair project! Read more
Speleology: Counting Formations in a Local Cave
Science Fair Project Idea
Scientific Method
Caves have been used for much more than just exploring throughout Earth's history. Caves have been used for shelter, for religious purposes, and for burial sites. They were even used for food storage, before refrigeration, because they are cool and have constant high humidity. But how are caves formed? What causes those fantastic formations in caves? How do cave formations change as you go deeper in the cave? Get ready for an adventure as you visit a local cave and learn more in this science… Read more
Underground Water Flow and Darcy's Law
Science Fair Project Idea
Scientific Method
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
