Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
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.
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.
How sweet is this activity? It’s an introduction to the rock cycle using chocolate!
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.
This activity enables students to estimate and calculate scales of distance and length as used by ocean drilling scientists.
Investigate different types of soil by using a core sample.
Static electricity can be used to demonstrate the electricity of lightning. This activity will demonstrate the attraction of positive and negative charges and what happens when those opposite charges meet each other.
Dendrochronologists use tree rings to go back in time to learn more about past climate. Using straws to recreate tree rings, you can learn how dendrochronologists work.
When warm and cold air masses meet, a thunderstorm can grow. Thunderstorms also cause heavy rain, flash flooding, hail, strong winds and tornadoes. In this activity, you will learn about convection and how air moves.
