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 different states of matter. Part of the Science Video Vocab Series.
In this episode, host Jason Silva explores the many layers of language. Some of the exercises and activities focus on the evolution of words, the links between what one sees and hears, and the mysterious communication abilities of twins. Part of the "Brain Games Family Edition."
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 what it means for substances to freeze. Part of the Science Video Vocab Series.
In this episode, host Alex Dainis takes viewers on a tour of her lab. She points out important equipment and tools and explains their purpose in the conducting scientific experiments.
Examines the primary characteristics of reptiles through narration, song, and close-up photography. Points out differences between animals within the species. Labels identify key words.
Follow a structural engineer through a busy day of working with sophisticated design tools. He is tasked with creating safe, long-lasting structures. Part of the "Career Connections" series.
Discusses the various body structures that enable microorganisms to move and function in their habitats. One of nine segments in a series, with all nine available on a DVD.
The Big Bang theory is currently the most popular scientific theory for the origin of the universe. It describes how the universe emerged from an enormously dense and hot state about 13.7 billion years ago and how the universe is still expanding from that point. This theory helps scientists explain the formation of all the galaxies, stars, and planets.
Since the invention of the internet during the 1960s, computer servers have been used for the exchange of information. Today things have changed; anyone can transfer files. Individuals can transfer files from one point to another or house them in a specific location within the network which can be used later for consultation. This is what is called "the Cloud".
In Australia, scientists have found dolphins using tools to find food. The bottlenose dolphin has been observed covering their beaks with basket sponges as they forage for food. The sponge helps them uncover fish hiding in the sandy sea bottom and protects their snouts from scrapes and stings. Part of the "News of the Day" series.
Summarizes beagle history and explains the breed's personality, characteristics, health care, grooming, training, housebreaking, and special abilities. Also points out choosing the right dog and how to find a reputable breeder and a healthy dog.
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.
Most people view antibiotics as miracle drugs. They can get rid of a whole range of infections. But because they are prescribed for so many different ailments, they are easy to overuse. The medical community is now at a crisis point because many of them simply don’t work anymore. Scientists are hunting urgently for new antibiotics--a challenge that is taking them to some remote and unusual places.
Insects can be found in baking deserts, lush rainforests, and all points in between. For most, their size seems insignificant; however, the influence insects have on the planet is immense. They make it possible for reptiles, amphibians, and mammals to exist. Part of the "Nature's Microworlds: Insect Specials" series.
Homeostasis refers to the body’s ability to maintain a stable internal environment, and maintaining homeostasis requires that the body continuously monitors its internal conditions. From body temperature to blood pressure to levels of certain nutrients, each physiological condition has a particular set point. Topics covered include homeostasis, negative feedback loop, nervous system, endocrine system, digestive system, excretory system, musculoskeletal system, and the immune system. Part of the "Biology" series.
Understanding the interatomic forces that give structure and properties to different types of solids is essential for the creation of new alloys, the development of useful polymers, and the creation of many other kinds of materials. Chemistry is not only an excellent entry point to predicting how a new material behaves but is also a continuous process of innovation and discovery. Part of the series: Chemistry: Challenges And Solutions.
Earth’s climate is changing in a big way, and it’s because there's more carbon dioxide in the atmosphere than at any point in human history. But Earth’s climate has changed before. How are scientists studying the impact of human behavior on climate? They are collecting ice cores and analyzing the tiny bubbles of ancient atmosphere trapped in the cores. Part of the "It's Okay to Be Smart" series.
In the last few years, the Red Planet has yielded up many new clues that life may have once existed there...and may even exist there today. There is now proof that water once flowed on the surface, that Mars once had lakes, and that the frozen poles are mostly water. Mars has snow--an aurora--and lightning generated by dust storms. Most intriguing of all are the seasonal plumes of methane that just may point to bacteria living below the surface.
Join vulcanologists as they venture into the heart of Ethiopia's Erta Ale, the oldest live volcano in the world, to ply its secrets of creation. Their mission to sample molten rock from the lava lake requires hauling more than 1000 pounds of gear to the crater, and then rappelling into the active cone. Blistering heat and sulfur stench greet them as they battle this formidable boiling mountain for the sake of science. Segment of video from Wild Chronicles Series.
