From Dragonfly TV. Marie and Michelle explore the California Cavern (10 miles of underground tunnels and chambers) to answer this DFTV question: How do cave formations change as you travel to the deepest parts of the cavern?
Cave formations called speleothems are mineral deposits that build up on the ceiling, floors and walls. The two most common are the ones that grow from the ceiling down, called stalactites, and others that grow from the floor up, called stalagmites. The gi
Caves - Extreme Conditions for Life
For certain life forms on Earth, conditions that humans and other familiar organisms find hospitable can actually be deadly. Instead of a moderate climate with an atmosphere rich in nitrogen and oxygen, these organisms thrive in very hot or very cold temperatures, or in caves or deep waters where no light penetrates. In this video segment adapted from NOVA, scientists analyze communities of cave-dwelling microbes that live off simple inorganic compounds like iron and sulfur. Based on their findi
Cave Formations: Biogeochemical Cycles
The most common process by which limestone caves form involves carbonic acid — or weakly acidic groundwater — as the primary agent. When carbonic acid contacts limestone, it dissolves minerals in the rock. If enough water to saturate the rock is present over a long time period, cavities and entire underground cave networks can form. Recently, a radical new theory has been proposed that identifies another cave-forming agent: sulfuric acid. This video segment adapted from NOVA identifies the m

Fossil Fuels - by StudyJams
Heat and pressure have turned the fossils of dead plants and animals into deposits of fuel, such as oil, natural gas, and coal. Fossil fuels are a non-renewable resource, and they create pollution, so it is important to conserve them. Learn more about fossil fuels with this slide show from StudyJams. Details images are set to music while information is written under each photo. A short, self-checking quiz is also included with this link.
Acceleration Part II
An animated locomotive helps explain how acceleration works and is calculated. The importance of reasonable units is stressed. Concept: Acceleration = m/s2.
