1 available in Juvenile Nonfiction, Call number: J 551.4 BRESummary: This program looks at the way soils can vary even within a small area of a forest. A well-developed podzol is examined in detail, with samples taken from the center of each horizon and then analyzed for organic content, soil acidity, mineral content, and particle size distribution. The measurements and analyses demonstrate why three soil profiles can be so very different in closely contiguous...

Summary: When the USDA replaced MyPyramid with MyPlate, the goal was to simplify dietary recommendations by providing at-a-glance guidelines without having to weigh and measure at every meal. This program explores the key concepts of MyPlate and how it correlates to the more detailed Dietary Guidelines for Americans, including portion sizes, proportions, food group choices, and caloric balance. The...

Summary: This program analyzes the dynamic nature of rivers and the relationship between their forms and processes. It examines the various functions a single river needs to perform, and shows how to measure river form and process, relate the two, and synthesize several attributes of the form of a river channel. It examines the differences between low and high flow, and explains how to calculate the...

Summary: Sediment sequences deposited under glacial conditions during the Pleistocene period cover some 10% of the earth's land surface. This program concentrates on the interpretation of a sediment sequence exposed in a river cliff cut by the River Severn in England. Techniques of sampling and analysis are illustrated, with emphasis on the measurement of particle size and of particle dip and...

Summary: Have Earth's vibrant waterways-its streams, rivers, lakes, and oceans-become delivery systems for pollutants and poison? This program points to signs that toxic substances are overwhelming our planet's aquatic ecosystems. Viewers encounter many of the causes for this concern, including a radical decrease in frog populations, distressed marine mammals in estuary habitats, and disturbing changes...

Summary: At ground level, shallow seas, broad beaches, dunes, and waterlogged hollows seem to comprise a chaotic environment. In fact, there is order and form, produced by the interaction of wind, vegetation, and moving sand. Because sand dunes develop rapidly, the development of a landform can be observed. Measuring wind velocity demonstrates how saltation, sand movement, and erosion happen. The...
