Conserving the Canopy
Called "the queen of canopy research," Nalini Nadkarni explores the rich, vital world found in the tops of trees. A unique ecosystem of plants, birds and monkeys thrives in the treetops of the rainforest. Nalini Nadkarni explores these canopy worlds -- and shares her findings with the world below, through dance, art and bold partnerships. Run time 16:27.
The tropical rainforests of the world are home to thousands of species of plants and animals -- including many that remain undiscovered by scientists. This video segment from the Race to Save the Planet teaching module "Saving the Diversity of Life" explores both the ecological importance and fragility of the rainforest biome and its organisms.

Physical Geography - Forces that Shape Our Earth
Explore the major landforms of our world with spectacular video footage. Look at the various forces that affect our physical environment including glaciers, volcanoes, gravity, rivers, lakes and oceans, movement in the earth, wind and temperature changes. This video is a superb introduction to the ways all these forces work together to shape our planet.
The Proton in Chemistry Acids are often thought to be harmful, but acids have many important uses in industry. Both strong and weak acids and bases are shown to be found in the natural world and used in our daily lives. Demonstrations explain pH and how it is measured. Five of the top 10 chemicals used in industry are acids and bases.

Volcanoes 101 Today we know volcanoes are openings or vents to the interior of the planet. About 1,500 volcanoes around the world are considered active, about 90% rest in the Ring of Fire, a band circling the Pacific Ocean. While the Earth’s surface looks peaceful the crust is made up of slabs of rock that constantly shift, where the plates interact, volcanoes often form. Friction from shifting plates melts the Earth’s crust, causing ro

Using Cloud-Seeding (Geo-Engineering) to Solve Global Warming
This clip from the "Five Ways to Save the World" details a cheap, simple, and low-risk way to compensate for global warming.
If the reflectivity of clouds could be increased slightly, sufficient sunlight would be reflected to compensate for any future release of CO2 into the atmosphere. (09:37)

The Origin of Teflon
The slipperiest stuff known to man, Teflon has made a tremendous impact on the world. Invented by accident in 1938, it has gone on to become a substance in all kinds of household items. Created by mistake, PTFE (poly-tetra-fluoro-ethylene) is a long chain carbon polymer surrounded by fluoride atoms. The fluoride atoms fully enclose the carbon chain so that it can't react with other molecules. It wasn't until 1944 that the name "Teflon" became trademarked. Dr. Kiki gives us the skinny in this
Voltage, Energy, and Force
In a world of electric charges and currents, field, forces and voltages, what really matters? When is electricity dangerous or benign, spectacular or useful? The electric potential and its gradient; the potentials of atoms and metals; electric energy, and why sparks jump.
The Industrial Revolution

Science Extreme - Making it Rain...on Purpose
"The Chinese government promised and delivered a rain-free opening ceremony to the delight of thousands in attendance and millions watching around the world. During the rainy season how did they do this? Simple: They seeded storm clouds with iodide before they blew into the capital city causing the rain to fall long before they reached Bejing.
Sound extreme? When it comes to technology triumphing over climate, this is just the tip of the iceberg. Welcome to the 21st century and welc
