Convection is the density-driven movement of a fluid material. Often, convection is driven by either heating from below or cooling from above the fluid. When a liquid is heated, it expands slightly, which makes it less dense. The fluid with lower density rises up, in the same way that a party...

This activity allows students to construct a small-scale model of liquefaction, a hazard associated with strong-magnitude earthquakes. The sand, water, and ping pong ball(s) represent the composites of soil: sediment, water, and air, respectively. The shaking, representative of seismic waves, will...

"This PDF has students using a light and foam ball to demonstrate the changing phases of the moon. During the activity, students are encouraged to use scientific terms, like """"""""waxing"""""""" and """"""""waning-"""""""" to describe which phase the ball is in. This modeling activity can be the...

Trilobites were distinctly related to crabs and lived in the sea from 526 million years ago until they became extinct 250 million years ago. There were many different species and 17-000 types of fossil trilobite have been found, ranging in size from only a few millimeters to more than half a meter...

An oasis forms when precipitation falling in the recharge zone seeps into the ground where porous and permeable rocks are found at the surface. This groundwater may travel many miles through the aquifer and resurface where the porous layer is exposed. When this occurs in a desert region an oasis may...

One of the most frightening and destructive phenomena of nature is a severe earthquake and its terrible aftereffects. An earthquake is a sudden movement of the Earth, caused by the abrupt release of strain that has accumulated over a long time. For hundreds of millions of years, the forces of plate...

A normal fault occurs when rocks break and move because they are being pulled apart. As the area is stretched, the rocks move along the fault. Each movement causes an earthquake. This model demonstrates how a block of rock is extended by a normal fault.
