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.

Fractals are complex, never-ending patterns created by repeating mathematical equations. A math student at MIT delves into their mysterious properties and how they can be found in technology and nature. Part of the "Science Out Loud" series.
One of the areas showing the greatest impacts of climate change is Antarctica. These impacts are significant because Antarctica serves as the regulator of global climate patterns and helps redistribute heat throughout the planet. Antarctica also greatly influences the circulation of the world’s oceans’ currents. Due to Antarctica’s influence on global climate patterns, scientists and other experts are working together to ensure the protection of Antarctica’s environment. Chapter 8 of Air: Climate Change Series.
Drop balls to begin observations. Note this sim does not yet have a Keyboard Shortcuts dialog, and simple descriptions are in progress.

The gray seal population in the Northeast has risen due to protection policies enacted by the federal government. Due to the population increase, conservation biologists are conducting experiments by placing tracking devices on the seals. They are analyzing their diving history, travel patterns, and foraging habits.
Part of the "Chemistry in Action" series. Numerous real-life examples of elements are exemplified in the table. Animations and graphics illustrate concepts not easily achieved through other instructional strategies. Specific patterns in the periodic table are highlighted. Introduces the following terminology: atomic structure, atomic number, atomic mass, periods, and families.
One of the consequences of accelerating climate change is the alteration of rainfall patterns. This alteration is causing flash floods and severe drought in several global areas. The increase in droughts and flash floods is a source of global social problems and economic loses. Chapter 7 of Air: Climate Change Series.
Weather affects everyone's life. This program provides illuminating, live-action examples and explanations of different weather patterns around the world. Students will also learn the layers of the atmosphere and be able to explain the causes and effects of air currents and air pressure. Part of the "Way Cool Science" series.
A Scientist from NASA explains how to easily build an inexpensive planetarium to introduce students to star patterns. The activity also allows students to create their own constellations. Part of the “DIY Space Classroom Activities” series.
This video explores the daily condition of the Earth's atmosphere, and the factors that influence and cause weather. Special emphasis is given to the global processes that generate weather patterns. Other topics covered include conduction, convection, radiation, thermometer, barometer, air pressure, winds, anemometer, sea breeze, land breeze, doldrums, trade winds, prevailing westerlies, polar easterlies, and jet streams.
Different processes in nearby coastal oceans drive the ecosystems found in the Mediterranean climate zones. Atmospheric processes over the oceans influence seasonal rainfall patterns, while currents and ocean temperatures affect both local and regional climate conditions. Part of the "Mediterranean-Climate Ecosystems" series.
Hurricane season runs from June to November. During these months, all three requirements for hurricanes to form are present. Storms form off the coast of Africa and travel on currents of warm ocean water. Also, the wind patterns alter the location of the jet stream. Part of the "Seasonal Science" series.
Scientists at NASA’s Jet Propulsion Laboratory give tips on how to come up with a unique idea for a science fair project. In this segment, they encourage students to look around and ask questions about what they see. This can include observations about patterns, shapes, and behaviors. Part of the “How to Do a Science Fair Project” series.
Global warming is changing the intensity, duration, and frequency of precipitation. These changing climate patterns are altering the water cycle and negatively impacting the environment. As the climate of regions changes, life on earth is significantly impacted. The increased potential for flooding raises concerns over loss of life and property, and individual actions are critical to lessen global warming and climate change. Chapter 4 of Air: Climate Change Series.
Weather forecasting has changed from a day-to-day guess based on local observation to a scientific method dependent on global data collected accurately, in detail, and at set times. Traces the progression of forecasting from data-collection methods to regional centers for computer plotting and analysis to prediction of weather for the next five to seven days. Includes why forecasting is important.
The human brain is wired to perceive patterns and structure in surrounding environments. Young children especially need structure to feel secure. Yet the developing brain is also continuously seeking new information. Discover how to give young children the structure they need to establish a strong foundation for continual learning. Part of "The Brain" series.
Ancient civilizations such as the Babylonians, the Chinese and the Greeks studied the stars without the benefit of telescopes and yet identified patterns of stars that are still used today. These early scientists collected the first data in the science of astronomy. This program provides students with a summary of the history of astronomy and highlights many important astronomers.
I think what your eyesight does is confirm other senses, says James Robertshaw, a world champion kite flyer and for two years personal assistant to Rory Heap. Heap has been blind from birth, but with Robertshaw's assistance pursues his ambition for kite flying--particularly of complicated figure eight patterns. Using all of his senses except for sight, Heap learns how to fly a kite with the same dexterity that Robertshaw uses to guide him through busy city streets.
Imagine if there were electronics able to prevent epileptic seizures before they happen, or electronics that could be placed on the surface of a beating heart to monitor its functions. The problem is that such devices are a tough fit. Body tissue is soft and pliable while conventional circuits can be hard and brittle--at least until now. Materials scientist John Rogers at the University of Illinois Urbana-Champaign is working to develop elastic electronics.
In recent years, the number and scale of wildfires in the U.S. has risen, threatening cities and forests and forcing large-scale evacuations. NSF is supporting the WIFIRE initiative, led jointly by UC San Diego and the University of Maryland, to better monitor, predict, and mitigate wildfires in the future. Part of the National Science Foundation Series “Science Nation.”
