How to Make a Cloud in Your Mouth

Description:  This phenomenon can be used to show how water moves from the atmosphere to the hydrosphere. The humidity of the air in the mouth is increased by moving the tongue, releasing water from the salivary gland. The pressure in the mouth is increased and then rapidly decreased causing small droplets of water to form. The same phenomenon occurs as moist air moves up in the atmosphere eventually forming clouds. A light can be used to make the cloud more visible.

Learn how to make a wispy cloud come out of your mouth, even when it's not cold out. Like any awesome trick, physics is to thank for the mouth cloud. This simple and fun demonstration can be used to explain the cloud in a bottle experiment, and real clouds in the sky.

Epic Mudslide Caught on Camera

Description:  Various forms of mass wasting (e.g. creeps, slumps, landslides, mudflows) can be used to show that earth events can occur quickly or slowly. Mass wasting occurs as gravity acts on the soil and rock in an area. The amount of water in an area greatly affects the speed of the mass wasting.

Fri, Jul 13: Global National's Francis Silvaggio and crew were at the scene of an incredible mudslide at Johnsons Landing in British Columbia on Friday. Global News cameras were rolling the whole time.

Why Do Rivers Curve

Description:  A meandering river is a great example of a phenomenon of water changing the shape of land. When it is surrounded by steep rock a river rarely curves but when it open up in large valleys it will weave back and forth. Water on the outside of the river will travel faster and erode the land more quickly. Eventually it will curve too much and lose speed. A stream table can be used to model a meandering river.

Augmented Reality Sandbox

Description:  The augmented reality sandbox uses technology to visualize earth science processes. A camera measures the depth of the sand which is then projected with different colors on the sand by an overhead projector. The technology allows a topographic map to be manipulated in real time. Water can be added to the system to show the interaction between the geosphere and the hydrosphere.

The Augmented Reality Sandbox allows students and the public to interact with a miniature landscape, sculpting mountains, valleys, rivers and even volcanoes, with off the shelf readily available parts. Topographic maps are crucial tools used by geologists, geographers and adventurous hikers. A newly-built apparatus at UCLA makes topographic maps fun and interactive for everyone by projecting them in 3D.

How Was The Grand Canyon Formed?

Description:  The Grand Canyon is a mile-deep and was carved by the Colorado River over millions of years. This phenomenon shows how consistent weathering and erosion over a long period of time can radically shape the earth. Even though the work of the Colorado took millions of years this is relatively rapid compared to the billions of years of deposition revealed by the Canyon. A trip down into the Grand Canyon is literally a trip back in time written in the rocks.

In the 19th century, many people believed that landscapes like the Grand Canyon were shaped by volcanoes and earthquakes. But one American geologist named John Newberry had different ideas. From: AERIAL AMERICA: Natural Wonders http://bit.ly/1TgPbSx
