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.

Many viewers enjoy three-dimensional technology, but a few feel the need to look away. A number of neurological and visual conditions can cause someone to experience nausea. It's a type of motion sickness without the motion. Fred Bonato of St. Peter's College in Jersey City has spent years steadily tracking what he calls "cyber sickness.”
Defining color is a complex process that has consumed artists and scientists for many years. Takes a new approach to the understanding of color, providing a comprehensive overview of what it is, along with very clear, detailed explanations. Three-dimensional graphics help enable full understanding of all the dimensions of color and how it relates to creative visual arts.
The researchers are building scaffolds that mimic the three dimensional structure of human tissue. They use a machine called a biofabricator to deposit cancer cells at strategic locations inside the 3D structures, just like tumors in human flesh. These structures are high fidelity test systems. Burg and her team can culture cancer cells in them, experimenting to see which treatments are the most effective, with the ultimate goal of personalizing a treatment or a vaccine for individual patients. Part of the National Science Foundation Series “Science Nation.”
Meet Boss – the car that can drive itself. Boss is the invention of Carnegie Mellon researcher Raj Rajkumar and his team. It has 18 sensors, including a three dimensional laser and onboard computers that connect to GPS and mapping software. When it comes to knowing the rules of the road, Boss rarely makes a mistake. With support from the National Science Foundation, it was built for a Department of Defense competition called the DARPA Urban Challenge. Boss negotiated the roads, including traffic, and was the hands down winner in 2007.
Molecules form when individual atoms create bonds by sharing electrons. Understanding how atoms combine to make molecules allows scientists to predict many of the physical and chemical properties of substances. Since the outermost eight electrons are key to forming compounds, this unit shows how the Octet Rule provides a basis for predicting how atoms may gain, lose, or share electrons to fill the slots in their outer shells. A fundamental understanding of how electrons form bonds leads to the three-dimensional shapes of molecules and has implications in all aspects of chemistry. Part of the series Chemistry: Challenges And Solutions.
The image of a rat sniffing around for food with its little whiskers moving back and forth to help satisfy its appetite is enough to make most people lose theirs. But those whiskers play a valuable role in helping rats determine what is in the environment around them. With support from the National Science Foundation, Mitra Hartmann and colleagues at Northwestern University in Chicago are constructing whiskered robots that can detect and then project three-dimensional virtual images of objects on to a computer screen. Scientists here don't think it's so far-fetched that one day robotic rovers, much like the ones on Mars now, might contain a set of whiskers to help them navigate the terrain around them.
Great inventions exist in the world of audio and music: stereo, surround sound, and holophonics, all known as 3D sounds. Although holophonics can be confused with surround sound because it tries to create a surrounding with sounds from different sources, holophonics have a completely different system and are only emitted through a stereo system, which when used with headphones and creates a sense of three-dimensionality.
The Three Gorges Dam is the largest hydro-electric dam in the world. Yet questions abound over environmental and social issues, not to mention the logistic problems of moving ships up and down the river. An ingenious system of ship locks has gone towards solving that problem, echoing the techniques of Banaue farmers in the Philippines who mastered the art of managing water over two thousand years ago.
Do the continents move? In this segment, students learn the relationship between a molten core, plate tectonics, and continental drift. Part of the "Earth Science" series.
Explores the pros and cons of building the Three Gorges Dam across the Yangzi River in China to control floods and generate electricity. Expected to be completed in 2009, it will be the biggest dam ever built anywhere in the world. Two million people will be displaced and 1,400 towns and villages will be flooded. Asks the question: Are the potential benefits worth the costs?
Updates the five kingdoms classification scheme with the latest understanding of life's organization based on DNA, fossil, and biochemical evidence, reorganizing all life into three great branches: Archaea, Bacteria, and Eucarya. Shows concise animations and superb microscope footage of primitive cells.
The Standard Deviants discuss the three laws of Sir Isaac Newton. This branch of study is also known as Newtonian physics, and it applies to everyday conditions of speed, time, and gravitational pull. Other topics covered include forces in equilibrium, mass as opposed to weight, inertia, static and kinetic friction, and tension. Part of the "Standard Deviants School: Physics" series.
In this behind-the-scenes glimpse into cataloging at The Field Museum, host Emily Graslie learns how to number small skeletal samples in the mammal collection. She also visits the seal fossil collection and examines the differences between the teeth of various species. Part of "The Brain Scoop" series.
In this episode, groups of citizen scientists use apps and maps to help researchers gather data about medical conditions. Sensors on asthma inhalers generate real-time maps of environmental dangers to help patients and physicians in Louisville, Kentucky. In West Oakland, California, citizens confront air pollution and rising asthma rates by collecting traffic data. Citizen scientists are fighting mosquito-borne diseases with apps and crowd-sourced data in Barcelona, Houston, and New Orleans. Part of "The Crowd and the Cloud" series.
Why do some power cables have two conductors and some have three? Ladyada explains that three prong cables are grounded and provide a layer of safety in electronics. Ladyada and Adabot go through the lab looking for grounded items. Part of the "Circuit Playground" series.
Diagram of a lithium atom. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.

Rocks, a naturally formed material that covers the earth, are classified by their origin. Discusses rocks' composition, three types (igneous, sedimentary, and metamorphic), how they are formed, and how they are changed. The rock cycle is a slow, ongoing process.
Cars use airbags. Packages use airbags. Why shouldn't eggs use airbags too? Students model NASA's airbag landing system in this activity from "Design Squad Nation." They design and build protective covers made of balloons to protect an egg dropped from a height of three feet. Their systems model the airbag landing systems used by three NASA Mars missions. The students use the engineering design process, apply a variety of science concepts, and learn about NASA's exploration of the solar system. Part of the "Design Squad Nation" series.
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. Manuel, Leo and Gabi arrive at a new planet where day and night go by very quickly. Only Leo understands their fast chatter. He is a tongue twister champion on Earth. Maqui takes this opportunity to explain the phenomenon of rotation to the three friends.
