This program provides an overview of the different types of foods. It also gives guidance on healthy eating. Students learn the difference between refined grain and whole grain. They also discuss the benefits of eating fruits and vegetables, how the body turns proteins into amino acids to build muscle and tissue, and the need to avoid processed foods. Part of the "Human Nutrition" series.

Today's telescopes study the sky across the electromagnetic spectrum. Each part of the spectrum tells scientists different things about the universe, giving them more pieces of the cosmic jigsaw puzzle. The most powerful telescopes on the ground and in space have joined forces over the last decade in a unique observing campaign, known as the Great Observatories Origins Deep Survey, or GOODS, which reaches across the spectrum and deep back into cosmic time.
The Very Large Array, or VLA, is a complex of 27 massive antennas on the Plains of San Agustin in central New Mexico, all pointing skyward to monitor radio emissions from the cosmos. With support from the National Science Foundation, astronomers use this facility to observe the most dynamic, cataclysmic events in the universe. Part of the "Science Nation" series.
The scientists will explore the color spectrum and explain why humans cannot see the whole spectrum. They will also create a solar oven using aluminum foil. Part of the House of Science Series.
Experts Eli Green, Jaymie Campbell, and Alessia Palanti define pertinent terms like cisgender, transgender, gender identity, gender expression, and pronouns. Viewers learn about gender norms and stereotypes that affect all people, no matter how they identify on the gender spectrum. Teens describe their personal experiences with gender and explain the critical importance of allies in their lives.
Using crisp images and lifelike animations, this program introduces students to the intriguing realm of stars and galaxies. The main characteristics of galaxies and stars are discussed. Special attention is given to the features of stars, including size, temperature, and brightness. The life cycle of a star is also highlighted, as are the tools used by astronomers to study space. Additional concepts and terminology illustrated in the video include: universe, telescope, satellites, constellations, star color, spectrum, gas, light-year, and black hole.
Visible light, which can be seen with human eyes, comprises a small sliver of the electromagnetic spectrum. The rest of the spectrum, from short wavelength gamma rays to long-wavelength radio waves, requires special instruments to detect. ALMA uses an array of radio telescopes to detect and study radio waves from space. ALMA is an advanced tool for studying very old stars and galaxies. These objects now are seen at great cosmic distances, with most of their light stretched out to millimeter and sub-millimeter wavelengths by the expansion of the universe. ALMA provides the unprecedented ability to study the processes of star and planet formation.
Students will learn how light is measured. Visual diagrams and hands-on experiments help students understand how light works. Important terminology includes wave, electromagnetic spectrum, wavelength, energy, reflection, lens, and prism.
Dr. Michelle Thaller explains the relationship between visible light and the principle of black-body radiation. These two aspects along with the anatomy of the human eye explain why stars don't appear green in the night sky. Part of the "Ask an Astronomer" series.
The invention of the lens goes far beyond the glasses that sit on one’s nose. Galileo used lenses to create the telescope and bring faraway things closer to mankind. At the opposite end of the spectrum, the lens exposed the microscopic world, leading to medical advancements including vaccination, anesthetics, and antibiotics.
Using real-world demonstrations and colorful graphics, students explore how light travels and how different mediums can affect light, resulting in reflection, refraction, and absorption. The color spectrum is also discussed through the use of prisms and paints. Part of the "Real World Science" series.
Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our zoom and magnification feature, so zoom in for a closer look, if you need to.

What is light? How does it operate? What are its properties? Why is it so important to the foundations of our physical world? Examines the nature of light and how it's harnessed in our lives. Explains the basic properties of light and the wave model. Also, discusses the concepts of wavelength, frequency, speed, reflection, refraction, total internal reflection, and dispersion. Explains the EMR spectrum, the color of objects, and the addition and subtraction of colors.
From a table at a bar, on a corner of the city of Buenos Aires, we discovered the nature of some of the “wave motion phenomenon” that surrounds us. Some of these were radio and TV waves or the ones from the microwave in the kitchen, solar light, X-rays and cosmic waves.
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.
