Critics and Challenges to the New Deal
During the Great Depression, America was searching for solutions. Because of this, people with radical opinions, who in better times would have been ignored, were able to capture the attention of the nation. Some made valuable contributions by presenting new ideas for debate. Others seemed to be merely obstructionist complainers or even rabble rousers just trying to make trouble. The majority, however, seemed to fall in an intermediate category of outspoken people who had many valid objections,

The Wonders of the Hydrological Cycle (and Human Impact)
The Hydrologic Cycle (or the Water Cycle) is a cycle of evaporation, evapotranspiration, precipitation and infiltration. (02:18)
The sun heats bodies of waters such as oceans and lakes, which causes the water to evaporate and form water vapor. Water vapor is also transpired from trees and soil. The collection of water vapor condenses to form clouds, which move around the globe by air currents. With the right conditions, clouds precipitate; some of the water absorbs into the ground t

Stories of the New World intrigued French rulers. Although they wanted a share of the American gold and silver, they were more interested in finding a westward route to Asia. In 1524, the French king commissioned Italian explorer Giovanni da Verrazano to search for a passageway through the New World. Verrazano spotted the coast of South Carolina and sailed north as far as Nova Scotia, but found no such water route or valuable treasure.
A decade later, French navigator Jacque Cartier led t

Elodea Cytoplasmic Streaming
About 10-15 minutes after preparing a wet mount of an elodea leaf, evaporation of some of the water makes it possible to see chloroplasts in motion inside of the cytoplasm. "Cytoplasmic streaming" is defined as the movement of the fluid substance (cytoplasm) within a plant or animal cell. This is the mechanism for the transport of nutrients. Run time 02:31.
