A Model of Three Faults
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 tectonics have shaped the Earth as the huge plates that form the Earth's surface slowly move over, under and past each other. Sometimes the movement is gradual. At other times, the plates are locked together, unable to release the accumulating energy. When the accumulated energy grows strong enough, the plates break free. If the earthquake occurs in a populated area, it may cause many deaths and injuries and extensive property damage.
A Paste with a Taste
To allow students to produce a "marketable" product made from minerals that are used by most people every day. Both the abrasive and cleansing compounds found in toothpaste, calcium carbonate and sodium bicarbonate, are minerals.
In this activity you will use seeds to model mining valuable materials from rocks.
Students will become familiar with fire terminology, realize how fire can be used as a management tool, and better understand the factors that need to be considered when planning a prescribed burn.
Chemistry of Burning
Why is CO2 increasing in the atmosphere? Who is doing it? Many people think that CO2 is “pollution,” so that clean burning should be a way to eliminate greenhouse gas emissions. In this demonstration, we review basic chemistry (see illustration) to realize that producing CO2 is an inevitable product of burning any fossil fuel.
Chocolate Rock Cycle
How sweet is this activity? It’s an introduction to the rock cycle using chocolate!
Climate and Temperature
Learn how Earth's climate effects soil types all over the planet.
Drilling is the only way to be sure that oil and gas fields exist and exactly what is present in the formation. Core samples reveal the physical and chemical nature of the rock. In this activity, you will create a model formation and “drill” for samples.
Cupcake Core Sampling
Trying to "see" what is beneath the surface of the Earth is one of the jobs of a geologist. Rather than digging up vast tracts of land to expose an oil field or to find some coal-bearing strata, core samples can be taken and analyzed to determine the likely composition of the Earth's interior. In this activity, students model core sampling techniques to find out what sort of layers are in a cupcake.
How much of a danger does severe weather pose for the area where you live? You can compute the answer yourself in this exercise.
