Discover how the James Webb Space Telescope will help scientists studying the formation of stars. The telescope will provide infrared observations and give astronomers an unprecedented view of stellar birth. Computer models show how a giant cloud of gas and dust collapses to form stars and planets.
In this episode, host Margaret Thompson discusses the discovery of exoplanets. Exoplanets are planets revolving around other suns in the universe. The first exoplanet was discovered in 1995, and recently NASA has reported the discovery of over three thousand exoplanets.
Introduces water and its properties and uses. Shows water's three forms: liquid, gas, and solid and how it changes form through evaporation, condensation, and freezing. Emphasizes that all living things need water to survive. Demonstrates the water cycle and discusses ways people use this essential liquid.
The decade saw The Great War, The Flu Epidemic and the Titanic disaster. Ten years into the 20th Century and the world is grappling with some serious growing pains. In a decade racked by conflict, there were inventions that made the world both safer and infinitely more dangerous. Featured inventions include: the parachute, the gas mask, the toaster, the Tommy Gun, and sonar.
Will the oil spill in the Gulf of Mexico create dead zones? That’s the concern of University of Georgia marine scientist Samantha Joye. She’s headed to the gulf to investigate how the oil and methane gas discharged by the BP Deepwater Horizon spill is impacting the ocean microbes that live there. With funding from National Science Foundation, she is also looking at how the dispersants used to break up the oil are impacting marine life, including microbes, fish, and shellfish.
In Colorado, drilling for oil and natural gas using hydraulic fracturing, sometimes referred to as fracking, is big business. But questions about its impact on the air and water are far from settled. With support from the National Science Foundation, University of Colorado environmental engineer Joseph Ryan heads a team gathering data on the pros and cons of oil and natural gas development, including the use of hydraulic fracturing. Part of the National Science Foundation Series “Science Nation.”
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.
The temperature of the Earth is dropping, and superhero Autumn Ray must find a safe way to heat the planet. At first she thought the answer was to increase the amount of greenhouse gases, but Dr. Mother Nature tells her there has to be a safe balance of gases to regulate the temperature of the Earth. Part of "The Science of Climate" series.
Provides important steps you can take and become self-reliant to prepare for various emergency situations topics include: Weather-related disasters, hurricanes, tornadoes, blizzards, floods, wildland fires, earthquakes, power outages, terrorism, bio terrorism, pandemics, avian and swine influenza, radiation emergencies, effects of climate change, and other disruptions including civil unrest. Knowing what you and your family can do to prepare for any type of disaster will help reduce stress if a natural or man-made disaster occurs. Having the proper supplies and knowing how to use them can make a difference between life and death in time of an emergency. Explains how to store food and water and you can have hot, tasty meals without electric power.
Pollution is waste material produced from human activities. It impacts the environment in a negative way. Explores how pollution can affect the air, water, and land in the form of gases, liquids, and solids. Substances that constitute pollution in the environment include: greenhouse gases (CO2, smog, and industrial emissions), oil, blue/green algae, plastic, litter, dog poop, and fertilizer. Also explores how a sustainable future depends upon individuals and society minimizing pollution by making informed and responsible decisions when choosing consumer items.
Scientific evidence may show that human activity, particularly over the past 100 years, has led to a buildup of what are known as "greenhouse gases," the most common of which is carbon dioxide, in the atmosphere. Energy use, particularly the burning of fossil fuels and the large-scale removal of vegetation from the earth's surface, are thought to be largely responsible for greenhouse gas buildup.
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 energy. Part of the Science Video Vocab Series.
Matter is made up of tiny particles called molecules. Host, Max Orbit, helps students learn all about the different properties, qualities, and characteristics of matter. He also discusses solids, liquids, and gases. Part of the "Way Cool Science" series.
Often hard-to-understand concepts of air, gases, air pressure, and layers of the atmosphere are plainly explained in this video. Concepts and terminology: oxygen, nitrogen, layers, weather, jet stream, and northern lights.
Hydrogen is the chemical element with the symbol H and atomic number 1. With a standard atomic weight of 1.008, hydrogen is the lightest element in the periodic table.
Saturn has twenty-one moons, and each one has its own physical composition and location. From the Kool Books series narrated by Hector Bonilla.
