Can we trust the robots of the future? Explores the world of artificial intelligence, taking us into labs and workshops where innovators teach robots to perceive, think, and move just like human beings.
Dr. Ronald Evans reviews how cell receptors called PPARs regulate body weight by controlling fat burning or storage. Part of the 2004 Howard Hughes Holiday Lecture Series.
Very little in the physical world around us occurs without chemical reactions being involved. Takes an in-depth look at five common products that are in use all around us. Also, explores the chemistry behind their manufacture and/or use, including chemical equations. The products are soap, polystyrene, aluminum, paint, and car batteries.
Using a balanced chemical equation to calculate amounts of reactants and products is called stoichiometry. It is a super technical-sounding word that simply means using ratios from the balanced equation. Topics covered in this program include the metric system, balancing equations, molar conversions, mass percent, empirical formulas, and limiting reactants. Part of the "Chemistry" series.
Documents efforts to contact and communicate with potential extraterrestrial life and interstellar space. Attempts to answer the question: Are we alone? Looks at the Drake equation, the standard for anyone seeking to find the number of planets with intelligent life in the Milky Way galaxy. Discusses the pioneering research at the Search for Extraterrestrial Intelligence Institute (SETI) based in Mountain View, California.
Part of the "Chemistry in Action" series. Chemicals interacting with each other are one of the most fascinating topics in chemistry. Fireworks, burning flares, and rusting all illustrate chemical reactions. Describes the different types of reactions as well as the process of balancing chemical equations. Introduces the following terminology: chemical equations, Law of Conservation of Mass, decomposition and synthesis reactions, replacement reactions, and reaction rates.
Observe changes to the equation and wire as you play with the resistivity, length, and area sliders.

How did the universe form? Where did it come from? Where does Earth fit into the equation? This segment focuses on Earth's place in the universe. Other topics covered include the solar system, gravity, planetary experience, and stars. Part of the "Earth Science" series.
From cooking food to enjoying the warmth of a fire, chemical reactions happen every day. Students learn the major characteristics and types of chemical reactions. Additional concepts and terminology discussed include: reactants, products, physical and chemical changes, chemical equation, reaction rate, and indicators of chemical reactions.
Dr. Corina Tarnita describes the importance of termite mounds in a savanna ecosystem. Termite mounds are biological hotspots that concentrate nutrients. When viewed from above, the mounds form a strikingly regular polka-dot pattern. Dr. Tarnita uses mathematical modeling to explain the regularity of the pattern.
A scientist from NASA explains how to build a rocket powered by rubber bands. Part of the activity includes launching the rocket from various angles to study trajectory. The activity provides students with an excellent hands-on perspective of key mathematical concepts. Part of the “DIY Space Classroom Activities” series.
Things really get spinning with a discussion of accelerated circular motion. The Standard Deviants explain rotational motion, which is the rotation of objects like planets. Along the way, students learn about radical radians and linear momentum. Part of the "Standard Deviants School: Physics" series.
How far is a star or a galaxy? Scaling and measuring the cosmos is a complex problem. Scientists are integrating mathematical applications and scientific technology to create measurement standards. Distances are so vast they are described in light years, and nearby stars are measured by trigonometry. Farther out, astronomers use standard candle measurement for deep space exploration.
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 scalars. Part of the Science Video Vocab Series.
Play with voltage and resistance sliders and observe changes to the equation and circuit.
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.

Is light composed of waves or particles? Explores the wave model of light from its earliest roots to our modern understanding of electromagnetism in 17 computer-animated video modules. Expresses Empedocles' belief that light streams from the eye, Aristotle's conception of light as a disturbance in ether, and Euclid's mathematical, ray-centered paradigms. Presents the Cartesian sine wave model, Huygens' principle of bending wave fronts, the electromagnetic spectrum, and aspects of particle theory. Provides an overview of diffraction, interference, polarization, and dispersion. Also explains Young's double-slit experiment.
