What helps seeds grow? Where do they come from? What is pollination? How does it happen? An elementary class experiments to find the answers. Time-lapse photography and illustrations reinforce the concepts.

Presents the principles of atmospheric dynamics. The Earth's atmosphere is a balance of gases and sunlight that allows for the possibility of life. It has a composition, structure, and life sustaining biological, geological, and chemical cycles in its lower reaches. Also, discusses how these atmospheric elements are being impacted by the unprecedented burning of fossil fuels.
An expert on exercise physiology discusses the importance of different elements of fitness, and teenagers share personal stories about how exercise helped them achieve and maintain a healthy weight. Exercise also helps build strength, develop endurance, improve agility, boost self-confidence, and connect socially. John Ratey, a professor of psychiatry, describes the growing evidence that aerobic exercise remodels our brains, making us sharper mentally, and providing protection against mood disorders. Teens describe how exercise helped them deal with depression, anxiety, and stress.
Since the beginning of time, humans have used chemical reactions without understanding them. For example, ancient Greek artisans were able to smelt metal, dye fabrics, and make glass. The attempt to transform simple metal into gold and silver was known as alchemy (the forerunner of chemistry as we know it today). By mixing elements, alchemists created chemical reactions which produced new compounds. While alchemists were never able to transform anything into gold or silver, their trails helped shape the science of chemistry. Part of Chemistry: Solved by Sherlock Olmos Series.
Powerful forces have forged the conditions on Earth that have made life possible. The millennia have been witnesses to the formation of the planet: its singular position in relation to the sun, the evolution of the continents, and the birth of entire mountain chains. All of these elements combine to create Earth’s constantly changing climate. Homo sapiens emerge into this unpredictable and violent world, fighting for survival from the start. It is these early humans’ ability to adapt that allows them to triumph even in the face of incredible adversity and sets the path for modern man. Part of the "How Climate Made History" series.
Using light as a probe, scientists found innovative ways to make inferences about the inner structure of the atom. In this unit, scientists discuss the change from believing the atom was a single indivisible particle to later understanding the atom is composed of subatomic parts. This new picture of matter lead to the development of the quantum model of the atom, as well as ways to identify traces of chemical elements, whether on earth, in the sun, or in a distant galaxy. Part of the series Chemistry: Challenges And Solutions.
Explores the open savannahs of Africa, particularly the mammals that inhabit them and the trees that border the grasslands. Shows how the different animals interact with each other and the non-living elements of their habitat to maintain a healthy balance. Also investigates the threat from an increasing human population for homes, food, other resources, and the resultant threat to the survival of many animal groups. Looks at international breeding programs around the world, which were established to protect these animals and enable them to reproduce in captivity, so their gene pool is preserved.
When the Maori arrived to New Zealand in 900 AD, it was one of the last places to be settled on earth by humans. They brought many elements of their Polynesian culture to the Islands, but none transformed the landscape as much as their use of fire. Modern Maori scholars shed light on the important role that fire has always played in their lives, as well as the inherent sense of conservation that is embedded in their culture and approach to the land. Part of WildFIRE PIRE series.
An early exploration (2015) into how to make a sim accessible has taken place for Forces and Motion Basics. It has working keyboard navigation and auditory descriptions for the 'Net Force' screen when the screen reader is in 'Forms' mode. We are working on updating the content so that it can be read by the screen reader in any mode. Notes for the main interaction: Press 'Enter' or 'Spacebar' to enter a group of pullers. Once in the group, use 'Arrow' keys to choose which puller you wish to select. Press 'Enter' or 'Spacebar' to select puller and move to knot selection. Use 'Arrow' keys to choose between different knots. Press 'Escape' to leave a group of pullers or knots, 'Tab' to leave group and go to next element. This prototype has been tested with NVDA and Firefox.

An elementary class prepares for a visit from the Shadow Players, a group who use light, shadow, and color to tell a story. The class learns about sources of light, shadows, and silhouettes. They experiment with transparent, opaque, and translucent objects to see what lets light through. Using a prism, they discover the colors in light. Review at the end.
Curiosity Quest visits an elementary school that is doing their part to protect the environment. The students have created a lunch tray recycling program, and host Joel Greene visits the cafeteria to see how the school recycles all their foam lunch trays. Part of the Curiosity Quest Series.
Anna has built a successful business from the ground up, and upon retirement, she leaves the company to her employees, not to her son. What does that decision tell us about Anna's psychology and about the development of the human brain over a lifetime? Explores the emotional and neurological elements of learning, explaining how the brain processes and stores experiences and prepares for future decision-making. Employing real-to-life dramatizations, Anna's journey from innocent teenager to philosophical retiree--and the changes that take place in her cortex, hippocampus, and neural synapses as she faces and overcomes challenges--are all depicted. In addition, several influential brain experiments from the past decade are described.
Some things die and decay and others don't. A walk in the park teaches that leaves, logs, and animals are examples of things that decay or rot. An elementary class buries apple, potato, and banana skins, bread, a plastic tray, and an aluminum can. They learn what decays and what will not. Some things that don't decay can be recycled; those that do, enrich the earth.
What are explorers? What do they do? What skills do they need? Is exploring done today? How can students be explorers? Following a summary of the 18-month Lewis and Clark expedition, elementary students learn about Will Steger, contemporary arctic explorer. Emphasizes the importance of keeping a journal to record what is seen and heard. Students explore nearby woods and share their discoveries.
Teaches caveman Zog that people use energy in one of two main ways: by moving heat from one place to another (conduction, convection, or radiation) or by transferring energy from one form to another by using an appliance, like a lamp or car. Appliances always waste some energy, and Zog learns why energy efficient appliances are the best choices people have today. As only a caveman can, Zog provides plenty of laughs along the way to finding clever and complete answers to elementary energy questions.
