Cosmetics are big business. They are used by almost every person walking on the Earth. Shows how cosmetics are made and how they have been used for thousands of years. Outlines bases, bulking agents, coloring agents, fragrances, and preservatives. Demonstrates the making of an emulsion and explains the processes of distillation or solvent extraction.
Welcome to the decade of Rock 'n Roll, drive-ins and McCarthyism. An America flush with cash and terrified of the "Red Menace" defines the inventions of the 1950s. Featured inventions include: the transistor radio, Sputnik, the flight data recorder, the Breath-a-Lyzer, and the hovercraft.
Debris flows are hazardous flows of rock, sediment, and water that surge down mountain slopes and into adjacent valleys. Hydrologist Richard Iverson describes the nature of debris-flow research and explains how debris flow experiments are conducted at the United States Geological Survey (USGS) Debris Flow Flume in Oregon.
Part of the "The Biology Classics" series. Daphnia are small, planktonic crustaceans. Provides a classic study in arthropod behavior and anatomy. Examines the eye, brain, jaws, intestine, legs (with gills), and heart. Identifies two kinds of eggs: those that hatch directly into female daphnia and resistant eggs that carry the species through periods of freezing and drying.
The ears are a masterpiece of miniature engineering, and our link to the world of sound. But their most important role is that they contain the tiny tubes that control our sense of balance. Presents the functions and parts of the ear in this look at the anatomy of hearing, speech, and balance. Graphics and microphotography vividly illustrate each part of the ear.
Covers Pomeranian history, personality, characteristics, health care, grooming, training, housebreaking, and special abilities. Also includes guidelines for choosing the right dog for a family, finding a healthy dog, and finding a reputable breeder or breed rescue organization.
Presents information on horses in magazine-type format. The first segment features children preparing for a vaulting competition (controlled gymnastics on the back of a horse). In the second segment four teens participate in a jumping competition at a horse show. Segment three shows a beginning rider visiting a tack shop to purchase riding apparel and equipment. In the last segment a professional horse trainer gives practical advice on buying a horse.
Shows the structure, behavior, and life cycles of planarians and their free-living relatives (class Turbellaria). Illustrates the bizarre life cycles of flukes (class Trematoda) and tapeworms (class Cestoda) with detailed animations and revealing images of these parasites in action.
Anything that takes up space or has mass is matter. Under certain conditions matter can be a solid, liquid, gas or plasma. Different states of matter can be combined in suspensions, and solutions and mixtures can be taken apart. Exploring the physical and chemical properties of matter provides insight into nature and a glimpse at how scientists and engineers use this knowledge to shape our world.
Vitamins and minerals are essential nutrients because they perform hundreds of roles in the body. There is a fine line between getting enough of these nutrients and getting too much. Eating a healthy diet remains the best way to get sufficient amounts of vitamins and minerals. In addition to vitamins and minerals, water is also essential for the optimal performance and regulation of the human body. Part of the "Human Nutrition" series.
In this chapter, other scientists from Kazakhstan will challenge the House of Science Scientists. During the challenge, the scientist answer the question does the temperature at which water or other fluids boil change according to the altitude of the geographical place? Part of the House of Science Series.
What does detergent do? The scientists research its qualities with an experiment. In this chapter, they will also conduct experiments in 2D and 3D to determine how vision works with different dimensions. The scientists will also explain the phases of the moon. Part of the House of Science Series.
Investigates rivers and their impact on land. Shows how rivers and streams are formed, and how they carve channels into soil and rock. Discusses stream classifications, the fluvial process, the effect of gradient, and how waterfalls are formed. Preview of vocabulary recommended.
The Curiosity Quest crew undertakes a stinky adventure at a water treatment facility. Find out what happens after flushing the toilet. Part of the Curiosity Quest Series.
The temperature of the Earth is dropping, and superhero Autumn Ray must find a safe way to heat the planet. At first she thought the answer was to increase the amount of greenhouse gases, but Dr. Mother Nature tells her there has to be a safe balance of gases to regulate the temperature of the Earth. Part of "The Science of Climate" series.
Part of the "Inside the Living Cell" series. Describes the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drinking in (pinocytosis) fluids. Also reviews membrane structure, osmosis, transport proteins, active transport, cell eating, cell drinking, and receptor proteins.
Chemist Paul Edmiston’s search for a new way to detect explosives at airports led to the creation Osorb. A swellable, organically-modified silica, or glass, capable of absorbing oil and other contaminants from water. Osorb has become the principal product of a company called ABSMaterials, where Edmiston is now chief scientist. With support from the National Science Foundation, Edmiston and his colleagues at ABSMaterials are developing water remediation technologies for cities and industries. ABSMaterials is creating formulas to address various contaminants, including hydrocarbons, pharmaceuticals, pesticides, herbicides, chlorinated solvents, and endocrine disruptors. Part of the National Science Foundation Series “Science Nation.”
Ever wondered how art museums decide if a painting is a fake? Nate meets with Dr. Gregory Smith, a forensic art scientist, to follow a painting they suspect is a forgery. They use everything from x-ray fluorescence to electron microscopy to figure this case out. Part of the "Artrageous With Nate" series.
Pretty ladybugs, fluttering butterflies, creepy daddy longlegs, and roly-poly bugs are some of the familiar creatures featured in this illustrated insect album. Based on the children's book by Bob Barner.
