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

If you were to orbit the Earth, you'd experience the feeling of free fall, not unlike what your stomach feels before a big dive on a roller coaster. With a little help from Sir Isaac Newton, Matt J. Carlson explains the basic forces...

In this episode of Crash Course Physics, Megneto helps Shini explain what induction is, how it works, and why magnetism is so seemingly complicated.

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...

In this video Paul Andersen explains how the atmosphere surrounds the planet. The state of the atmosphere is climate and is affected by unequal heating, the Coriolis Effect, and the ocean. Convection cells and ENSO are discussed in...

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

Why do some regions experience full-time heat while others are reckoning with frigid temperatures and snow? And why are the seasons reversed in the two hemispheres? Rebecca Kaplan explains how the shape of the Earth's orbit around the...

The fourth planet from the sun and the outermost of the terrestrial planets, Mars has long been a popular spot for missions and imagination. Phil walks you through the planet's topography, core, and features. We'll take a look back to...

New ReviewIf you're lost in the woods, your best chance of finding your way might be a tiny magnet.

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

Not only do they describe every electrical and magnetic phenomenon, but hidden within these equations is a fundamental truth about the nature of light, and why it is the ultimate speed of the universe. We...

What came before the Big Bang? what happened before the big bang? Since time is thought to have started at the big bang, asking what happened "before" is like asking what is North of the North pole? It may have no...

Discover how gravitational acceleration is calculated near Earth and why your weight changes with altitude, latitude, and Earth’s rotation. This lesson unpacks the physics behind g = a₉ − ω²R and shows how gravity subtly varies across...

Pupil outcome: I can locate and talk about the Arctic Circle using maps and globes, and describe seasonal changes. Key learning points: - The Arctic Circle is an imagined circle around the North Pole that surrounds the area known as the...

Pupil outcome: I can identify some of the wildlife found in the Antarctic and explain how it is affected by seasonal change Key learning points: - All the creatures that come to the Antarctic feed in the sea. - Penguins are only found in...

Pupil outcome: I can explain Earth’s movement and how the Sun gives us night and day and the seasons. Key learning points: - We have seasons because Earth is tilted on its axis as it orbits the Sun each year. - Each season has its own...

Pupil outcome: I can describe some of the threats to the polar regions, what is being done to address them and what more could be done. Key learning points: - Because an essay is a non-fiction piece of writing, it must be based on facts....

Pupil outcome: I can describe the world’s polar regions and explain a number of ways in which they are important. Key learning points: - Because an essay is a non-fiction piece of writing, it must be based on facts. - Facts are obtained...

Pupil outcome: I can interpret sets of negative and positive numbers in a range of contexts. Key learning points: - For negative temperatures, the further the number is from zero, the colder it is

Pupil outcome: I can describe how magnets can attract magnetic materials, as well as attract and repel other magnets. Key learning points: - All magnets have a north–seeking pole and a south–seeking pole. - Unlike magnetic poles attract...

Pupil outcome: I can write the first half of an essay about the effects of climate change on the polar regions, using a range of linguistic features and a formal tone. Key learning points: - Our essay gives a logical argument that builds...

Discover Earth's five oceans – from the vast Pacific to the icy Southern Ocean – uncovering unique features, marine life, and geographic features like the Mid-Atlantic Ridge.

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.
