The word "theory" is used differently in casual, everyday life than when discussing scientific matters. This episode discusses scientific theory and law. Part of "The Amoeba Sisters" series.

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 scientific theory. Part of the Science Video Vocab Series.
How did 20th-century physics change long-held notions of light's makeup and behavior? This group of 12 concise computer-animated videos illustrates Einstein's monumental contributions to the study of light. Shows how rudimentary ideas of material wave motion yielded to more advanced concepts of electromagnetic waves by detailing Einstein's conclusions about the speed of light and his conception of time, which-given his findings on mass and energy-proceeds according to variable frames of reference. Conveys relativistic thought experiments through helpful animation, which demonstrate simultaneity, time dilation, length contraction, and relativistic mass.
Students will trace the history of chemistry and study accounts of how chemistry developed from a practical discipline into a science. This episode also presents a current, real-life application of chemistry by illustrating the process of the refining and purifying pure silicon for advanced electronics, such as cell phones and solar cells. Part of the Chemistry: Challenges and Solutions Series.
No organism lives forever. The length of time animals and humans live is influenced by their genes. Scientists have made astonishing discoveries concerning the role of genetics in determining life span, and this holds promise of extending the lives of animals and humans. Explains genetics, DNA, and genetic theories of aging. Illustrates the genetic processes behind cellular aging, and shows how genes affect life span. Discover the reasons why cells age and why a certain enzyme can effectively turn back the hands of our "biological clock."
British naturalists Charles Darwin and Alfred Russel Wallace both set out on epic adventures to study various species and their development. They gathered evidence on the variation among individual members of a species, the relationships among species, and the patterns of geographic distribution across many species. Based on such evidence, they independently came to the same revolutionary conclusions: species change over time by means of natural selection, and species descend from other species.
A black hole is a region of space having a gravitational field so intense that no matter or radiation can escape. In this episode, host Dianna Cowern leads a discussion on black holes and reviews Stephen Hawking's last paper on black holes. Part of the "Physics Girl" series.
Host Emily Graslie discusses a new scientific theory about mammalian diversification. According to this new theory, placental mammals evolved before a major mass extinction event, which occurred sixty-five million years ago. However, there is no fossil record to prove the new theory, but scientists around the world used genetic material to form their theory. Part of "The Brain Scoop" series.
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.
Provides an overview of the cell--the building block of life. Covers different kinds of microscopes, the discovery of cells, and the cell theory before focusing on a cell's characteristics and organization. Includes a quiz.
It's called a theory, but if we have never seen an atom, how did anyone ever come up with an idea that is so central to science. Shows how all the pieces of the puzzle have come together at the same time, explaining the structure of the atom and the periodic table.
Actors portray prominent scientists and astronomers as they present the history of astronomy from Plato to Newton in its historical and cultural contexts. The Greeks reasoned that the universe was geocentric--the earth was at its center. Not until Copernicus did the theory of the sun as center take root. Each major astronomer declares his different theory until Newton's answers all questions about gravitational pull between planets.
The geologic processes of mountain building, seafloor spreading and volcanoes are a few examples of the power of plate tectonics. Footage filmed on-location in Iceland, the Canadian Rockies, and Crater Lake help viewers understand the theory of plate tectonics. Colorful animations illustrate the movement of tectonic plates and the role this plays in the development of geologic features. Other terminology includes: theory of continental drift, mid-ocean ridge, plate boundaries, subduction, convergent boundary, and divergent boundary.
Professor Jim Al-Khalili shows that in our quest to understand the tiny atom, we unraveled the mystery of how the entire universe was created. It's a story with dramatic twists and turns, taking in world-changing discoveries like radioactivity, the Atomic Bomb, and the Big Bang Theory. All this forms part of an epic narrative in which the greatest brains of the 20th century competed to answer the biggest questions of all-why are we here and how were we made?
Gabriela, Manuel and Leonardo are three friends who accidentally start a rocket that takes them to space. Their journey through space takes them to different planets and strange worlds. Throughout their journey, they have the help of Maqui, an on-board computer. Maqui helps them learn about the universe. The kids arrive at a planet to ask for directions on how to get to Earth. While visiting the planet, the friends learn that its inhabitants believe the entire universe revolves around this planet. With the help of Maqui, the friends explain that planets revolve around their suns. Everyone learns the difference between the geocentric theory and the heliocentric theory.
Is there life on other planets? How can it be found? Presents the scientific theory of life's beginning and evolution on earth before considering life within our solar system and beyond. Discusses possible planet formation from stellar dust and technology's place in locating such planets.
The formation of molecular bonds is an essential part of keeping matter together. The sharing of charges between atoms helps them become more stable. Other topics covered include sharing electrons, bonding tendencies, isomers, VSEPR theory, and molecular geometry. Part of the "Chemistry" series.
America’s largest recorded earthquake happened on March 27, 2014 in Alaska. United States Geological Survey (USGS) sent geologists to study the impact and effects of the earthquake. The information gathered from the aftermath was essential in resolving key mechanisms of the developing theory of plate tectonics.
Part of the "Inside the Living Cell" series. Provides an overview of the different kinds of cells, emphasizing the fact that all cells have a common organizational structure and carry out similar biochemical processes. Presents the discovery of cells, cell structures, organelle function, cell varieties, and the chemistry of life.
