Students learn and explore the major features of the skin, skeletal, and muscular systems. Special attention is given to the care and maintenance of skin, skeletal, and muscular systems. Concepts and terminology include: integumentary system, layers of skin, sweat glands, bone, osteocytes, periosteum, marrow, cartilage, ossification, types of joints, ligaments, types of muscle tissue, and voluntary and involuntary muscle.
Focuses on comets, those mostly unpredictable, wandering objects in the solar system. Uses time-lapse images while explaining a comet's tail and the meteors, or "falling stars," associated with it. Mentions Halley's and Hale-Bopp comets and international efforts to see these bodies more closely. Contains actual pictures of comets photographed by space probes.
Explores the need for many multicellular plants to have specialized internal transport systems, which are systems that can efficiently distribute materials from soil and leaves to the parts of the plants where they are needed. An overview of how plants obtain their nutrients is provided. The structure and function of root hairs is explored, explaining their remarkable ability to facilitate an enormous uptake of water and dissolved minerals for the plant. Following this, the separate transport systems of the xylem and phloem are explored in detail. Also explains the mechanisms by which vascular plants transport water and minerals upward from the roots as well as sugars from leaves and other sugar sources throughout the plant for storage or for growth and repair.
Satellite footage, telescopic photos, and animation are used to teach students about the many aspects of the solar system. Viewers are introduced to ancient astronomers, telescopes, observatories, and space exploration. Students will discover facts about planets, orbits, gravity, revolution, and rotation. The program also features discussions of the sun, comets, asteroids, and meteors. Part of the Real World Science series.
Discover what happens at the outer edges of the solar system where solar wind interacts with interstellar space. The Interstellar Boundary Explorer (IBEX) is a mission to study the boundary between the solar system and interstellar space. It collects data that shows the global structure and dynamic nature of the heliosphere.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term solar system. Part of the Science Video Vocab Series.
What are asteroids? Where are they? Are they dangerous to us? Explores this space body, its place in the solar system, and its potential threat to life on Earth. Discusses the LINEAR Project, which identifies and maps asteroids. Notes that meteorites are pieces of asteroids, and shows where both have hit Earth.
Touch, taste, smell, hearing, and sight: the human body's five major senses. They are senses that have evolved independently over millions of years but are brought together by our marvelous central nervous system into the most refined way of interacting with the environment of any species on the planet. Join Dr. Mark Reisman as he provides you with a look at the anatomy and physiology of each of these sensory systems and shows how the brain uses them to produce what we call being human.
Examines Mercury, the closest planet to the Sun. Uses photography from the Mariner fly-bys and animation to show the planet's surface features. Describes its characteristics, length of day vs. length of year, its two sunrises, and its orbit. Time-lapse images record Mercury passing across the Sun, an event that occurs only 13 times a century!
A total eclipse of the sun is the greatest spectacle in our solar system. Gives an in-depth explanation as time-lapse images capture the full impact of this event. Begins with a discussion of lunar eclipses before moving on to examine auroras. Explores the causes of auroras, and gives examples of two: the Aurora Borealis and the Aurora Australis.
Tracy Drain is a flight systems engineer at NASA's Jet Propulsion Laboratory in Pasadena, California. As a child she became interested in space, and now she makes sure all the parts and systems in a spacecraft work as expected. She enjoys solving new, complicated problems. Part of the "Design Squad Nation" series.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. For this particular video, students will focus on the functions of the human skeletal system. Part of the Science Video Vocab Series.
Astronomers are beginning to locate thousands of planets that exist outside of the solar system. Scientists provide a behind-the-scenes look at the simple technique that astronomers are using to discover these curious new planets. Part of the "Science Out Loud" series.
Our Sun is a nuclear reactor converting hydrogen to helium continuously. X-ray and telescopic images reveal the Sun's photosphere and chromosphere, sun spots, solar flares and winds, and prominences. Describes each and its impact on Earth. Covers some of the Sun's mysteries, and projects what will eventually happen to our closest star.
What happens in your brain when you get lost or forget something? Johns Hopkins University Neuroscientist Amy Shelton believes she can find the answer. With funding from the National Science Foundation, she’s testing human spatial recognition. Study subjects learn and recall their way around a virtual maze while an MRI scans their brains. By analyzing MRI images of blood flow in the human, Shelton can get a picture of how the brain learns and recalls the spatial world outside the body. By understanding those processes, she believes she can develop techniques that will help improve human memory.
The city of Ann Arbor, Michigan has turned to engineering research to tackle an issue facing many cities: aging stormwater infrastructure during a time of tight budgets, growing populations, and more extreme weather. With support from the National Science Foundation, civil and environmental engineer Branko Kerkez and a team at the University of Michigan are building a new generation of smart and connected stormwater systems. Part of the "Science Nation" series.
In 1977, Voyagers I and II left Earth for deep space exploration and a close-up view of the edges of our solar system. Reveals how the space shuttles used the gravitational fields from surrounding planets to slingshot themselves through the outer planets. Voyager II's graphics and real pictures of Neptune and Uranus help explain their features, axis, rings and moons, and magnetic fields. Also notes some peculiar facts about each.
Scientists believe that Saturn, the second largest planet, would float in water if a glass were big enough. Uses computer graphics to note its features and those of its seven rings. Discusses Titan, its largest moon, and the Cassini probe, which examines it. Notes Saturn is a gas giant, has a 30-year orbit, and that astronomers create theories about this planet based on limited facts.
Firefighters risk their lives every time they run into a burning building. But, new technology may soon be watching their backs, no matter how far they venture into the flames and smoke. With support from the National Science Foundation, TRX systems is developing a new sensor system that can track firefighters where GPS units often fail.
