When it comes to cost, clean energy is bound to beat out fossil fuels, says technologist Ramez Naam. But the hesitancy to build amid the prevalence of "not in my backyard" campaigns is preventing the creation of our sustainable future....

Let's learn all about the waves that we play in at the beach!

With winter in full swing, Jessi and Squeaks are snowed in for the day and passing the time with their favorite game: Guess That Animal!

As Squeaks continues to prep for his big trip with Jessi, Mr. Brown helps him learn all about how the wind outside the fort will also affect how long his airplane ride with Jessi takes!

Jessi and Anthony have been helping Squeaks learn all about flying before his big airplane ride to the robot museum so he isn’t so nervous! Here’s everything they learned together!

Jessi and Squeaks learn all about pine cones and their seeds today! Did you know that pine cones can open and close to help protect their seeds?

Squeaks went on a trip to the beach, and wants to tell Mister Brown all about it! And, we can learn all about the science that formed the beach, plus a guest appearance by Grady the tardigrade to talk all about the plants and animals in...

Names like Bayard Rustin, Frances Thompson and William Dorsey Swann have been largely erased from US history, but they and other Black queer leaders played central roles in monumental movements like emancipation, civil rights and LGBTQ+...

Architecture can't ignore the realities of climate change. For time-tested solutions that perform under extreme conditions, designer Alyssa-Amor Gibbons says we should look to traditional buildings. Taking us to her home of Barbados,...

Earth’s magnetic field is special! And, in the last 20 years, we’ve made incredible discoveries, thanks to a squad of probes that have flown around our planet, observing solar wind as a team!

In 2004, construction began on a new building in Dubai, promising a revolutionary design that would dwarf the rest of the world's skyscrapers. Five years later, the 828-meter Burj Khalifa was complete, surpassing the previous...

The physics of the perfect storm

Alternative energy is great, but our infrastructure isn't exactly equipped to handle it. So scientists are coming up with other ways to use it, including turning it into food.

Today Phil follows up last week’s look at the death of low mass stars with what comes next: a white dwarf. White dwarfs are incredibly hot and dense objects roughly the size of Earth. They also can form planetary nebulae: huge,...

There are a lot of weird places here on Earth, but here are a few of our favorite strange spots!

So... what makes the wind? You might be surprised to learn that it has to do with two of Earth's spheres; The Hydrosphere and the Geosphere. In this episode of Crash Course Kids, Sabrina takes us to the beach to chat about how the wind...

Some might call sand coarse, rough and irritating, but there’s no denying that it’s used everywhere: from glass to asphalt, sand is a key ingredient for all sorts of materials in construction and technology. But this heavy reliance on...

How do you tell a plane from a bird? The vertical tail, of course! By why can birds fly without a vertical tail, and how do planes use their vertical tails to stay in the air?

Stripes! Hexagons! They're everywhere! These patterns in nature might seem like aesthetic coincidences, but they are actually the result of physical process that show up again and again, even in otherwise unrelated phenomena.

Today is exciting, because Jessi and Squeaks are making parachutes! Tag along to learn how you can make your own, and what forces are being used to make your parachute work!

Ever have a staring contest? Why is it so hard?! Jessi answers a question from a curious SciShow Kids viewer: Why do we blink?

All around the world, millions of people are flipping a switch, plugging in, and pressing an 'on' button every second. So how much electricity does humanity use? And how much will we need in the future? Discover how much energy it takes...

Get an engineeer's-eye-view of the tallest buildings in the world, to learn what challenges they face as they reach for the sky and wonder, how tall can we build?

Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day. And unlike coal or oil, this resource is totally renewed each day. So how can we harness this incredible...
