By the early 1900’s, nearly every region of the globe had been visited and mapped, with only two key locations left: the North and South Poles. After two Americans staked claim to reaching the North Pole, a Norwegian explorer and a...

Paul Andersen explains how objects interact when touching and at a distance. Electromagnetic forces are very important when objects are touching and fields explain both electromagnetic and gravitational forces. The strong and weak...

In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed...

Antarctica wasn't always covered in kilometer thick ice sheets, in fact, scientists have spent years figuring out what turned this once lush continent into its current icy state.

It sounds like science fiction, but journalist Stephen Petranek considers it fact: within 20 years, humans will live on Mars. In this provocative talk, Petranek makes the case that humans will become a spacefaring species and describes...

The water on Mars probably doesn't have much oxygen, but new models show that life doesn't need as much O2 as we thought. And NASA is sending a claw machine to the red planet!

Mister Brown and Squeaks are here to teach you all about the compass - and they will even help you make your own!

In this final segment on the four fundamental forces of physics, Hank tackles the magnetic force, the second of the two ways in which electromagnetism is apparent in the universe

Is it in the Arctic Ocean? In Canada? Russia?

In this video Paul Andersen explains how magnetic domains act as tiny magnets within ferromagnetic material.

In this video Paul Andersen explains how all material has magnetic properties. Ferromagnetic material can be permanently magnetized, paramagnetic material will align with magnetic fields, and diamagnetic material will align weakly with...

You’re probably familiar with the basics of magnets already: They have a north pole and a south pole. Two of the same pole will repel each other, while opposites attract. Only certain materials, especially those that contain iron, can be...

NASA's Cassini spacecraft has detected a huge ocean under the surface of Saturn's moon Enceladus. But how? And what does it really mean? Hank lays out the data -- straight from space to your brain!

Jessi and Squeaks are working on an experiment: Making an ordinary magnet float in the air!

2 minute video demonstrating magnetism and magnetic properties for middle school science

Explore what happens if you fall straight through Earth—using Newton’s Shell Theorem, simple harmonic motion, and real gravitational data. Understand why every straight tunnel gives the same 42-minute trip, and how gravity behaves inside...

There is no time in the North and South Pole

Ernest Shackleton on his British Antarctic Expedition 1907–09, otherwise known as the Nimrod Expedition, the first of three expeditions to the Antarctic led by the Anglo-Irish explorer. Its main target, among a range of geographical and...

Take a trip around Earth’s seven continents and discover what makes them unique, from Asia's towering Mount Everest to the native wildlife of Australia to the frozen expanse of Antarctica.

How do we get from A to B? Cardinal and intermediate directions are a tool in geography that help us navigate the world around us.

It's been three years since NASA's Juno spacecraft arrived at Jupiter. But what has it seen and discovered? We will examine Jupiter's magnetic field, core, bands, aurora, atmosphere, storms and clouds.

Antarctica, the highest, driest, coldest, and windiest continent on Earth, is a land of extremes. With 99.6% of its surface covered in ice, it offers unique conditions for climate research. International scientists and researchers...

Feedback is a vital part of any manager or supervisor’s role. And that’s as true for Project Managers as for any other form of manager or leader. There are different types, but the one that gets...

The Stern-Gerlach experiment, which took place in 1922, was the most important proof that electrons have spin and that they have a spin quantum number. A stream of silver atoms was sent through an experiment using a magnetic field...
