7 Things We Don’t Know About the Ocean

The ocean covers 70% of the planet, but humans still don’t know very much about it. In this episode, Hank discusses seven mysterious ocean topics.

A Brief History of Plastic

For centuries, billiard balls were made of ivory from elephant tusks. But when excessive hunting caused elephant populations to decline, they began to look for alternatives. John Wesley Hyatt took up the challenge. In five years, he invented a...Show More

A Guide to the Energy on Earth

Energy is neither created nor destroyed — and yet the global demand for it continues to increase. But where does energy come from, and where does it go? Joshua M. Sneideman examines the many ways in which energy cycles through our planet, from...Show More

A Leap Forward for Life

In rural Australia, what can ancient fossils tell us about the first leaps of life on Earth?
Adapt or Die

Adapt or Die

In order to survive, every form of life needs to be adapted to its habitat. A ‘habitat’ is the environment or place where an organism lives. And being ‘adapted’ means being well suited or fitted to live there. Otherwise there is no future...Show More

Air Pressure and Heat

Discover how the force of gravity and air pressure work together in our incredible atmosphere.

Antarctica and the Ice Sheet

Explore the wonders of the massive ice sheets that cover Arctic plains.
Arctic Warming

Arctic Warming

The oceans absorb 90% of the heat from greenhouse gasses, causing ever more ice to melt.

Asteroid in Canda

Brian travels to Canada for an excursion to learn more about asteroids.

Asteroids and the Barringer Crater

In Arizona, the Barringer crater reveals how our planet comes into contact with another object.

Avalanche Experiment Results

An explosive experiment is underway on a snowy mountain top to understand how an avalanche is caused.

Avalanche Experiment: Hitting a Car

How does a small car fare in the impact of an avalanche?

Axis Tilt Effect

Did you know that Earth orbits the Sun on an tilt? Learn more about the axis tilt and how it impacts life on Earth.

Balancing Act

Do ballet dancers get dizzy? How does our 'sense' of balance work? It turns out there are quite a few things that feed into what we call balance. In the experiment, students will have the chance to test each other and see just how much balance...Show More

Why cutting CO2e requires pricing carbon.

Catastophes and How the Earth Has Coped vs Humans

Earth has been experiencing catastrophies since the extinction of the dinosaurs. How do we humans fare in the face of catastrophe compared to Earth?

Circuits and Switches

Electricity is central to our lives. But where does it come from, how is it made and transported, and what are some of its basic properties? Students will be using playdough, batteries and LED's to create a simple circuit which can then use to...Show More
Colourful Chemistry

It may not make the top ten list of 'foods kids love to eat', but red cabbage is a great addition to any chemistry experiment toolbox. Students will find out how the colour can be extracted from the cabbage and how it can change colour depending...Show More

Coral Bands and Longer Days

On the coast of Bermuda, a deep dive into the waters reveals how coral records the Earth's history.

Coriolis Effect

Like a ball curving when it's thrown, explore how Earth behaves in a similar manner referred to as the Coriolis effect.
Crater Maker

Crater Maker

Objects flying through space and slamming into planets may not seem that relevant here on Earth (thankfully it happens quite rarely), but it is a process that was key to forming the planet we have today, not to mention our moon and a lot of the...Show More
Current Events (Air Currents)

Current Events (Air Currents)

What are air currents? Air currents are like rivers of wind caused by areas of high and low pressure.The air above the land is warmer and less dense, so it rises. The air over the water is cooler and heavier. The cool air rushes in toward the...Show More

Discovering Cenotes

This clip explores the evolutionary catastrphe that proved to be in favour for humans.
