Squeaks and Jessi are spending the afternoon playing "Guess That Animal" and learning about some of their favorites!

Vultures, you eat old, putrid dead things for a living. How is that not killing you? Hank explains the secret weapons vultures use to fight off disease, avoid predators, and beat the heat. Prepare for a Sci-Show Gross-Out!

Part 1 of 3 in my series about why our bodies are shaped the way they are.

In tropical seas, flying fish leap out of the water, gliding for up to 200 meters, before dipping back into the sea. In the Indo-Pacific, a hunting sailfish swims up to 110 kilometers per hour. These feats are made possible by a fish's...

Here at SciShow Kids we're gearing up for the spookiest time of year! And today, we're going to learn all about ravens! Ravens may give you the creepy crawlies, but they have some awesome skills and behaviors that make them very clever...

Our month-long exploration of human reproduction continues with a look at testicular anatomy, the steps of sperm production, and how it's influenced by gonadotropin and testosterone. Hank also explains how sperm mature, and how...

If you hear the word “baby-faced” you might picture a doe-eyed celebrity who never seems to age. But, really, you should be thinking of the axolotl. However, it is possible to transform these otherwise forever-babies, causing them to...

Given that Earth’s magnetic field helps protect its life-sustaining atmosphere, you might think that the stronger a planet’s magnetic field, the better. But as it turns out, some planets’ relationships with their magnetic fields are a...

Cell membranes are structures of contradictions. These oily films are hundreds of times thinner than a strand of spider silk, yet strong enough to protect the delicate contents of life: the cell's watery cytoplasm, genetic material,...

Why can amphibians, fish and even some reptiles regenerate limbs, while birds and mammals can’t? Researchers think they might have found a clue on the tip of the alligator’s tail.

Renowned paleontologist Jack Horner has spent his career trying to reconstruct a dinosaur. He's found fossils with extraordinarily well-preserved blood vessels and soft tissues, but never intact DNA. So, in a new approach, he's taking...

This is part 3 of 3 in my series about how our bodies evolved to look like they do.

Laughter, love, and happiness are some of the best aspects of being human, and we've looked into the science behind it more than a few times. Here are a few videos that we hope will make you happy!

Magnetic fields fill our universe, but here at home we have a very special one that nature uses in a myriad of ways. And further away, other magnetic fields give us fascinating glimpses into the nature of the universe!

Soil ecologist Dr. Ylva Lekberg explains the connection between microscopic fungi and invasive plants, and Jessi from Animal Wonders introduces us to Sydney the woylie!

In this video Paul Andersen explains how vector addition can be used to determine the electric field of a dipole.

Inside our cells, each of us has a second set of genes completely separate from our 23 pairs of chromosomes. And this isn't just true for humans— it's true of every animal, plant, and fungus on Earth. This second genome belongs to our...

You probably have a vague idea of what sperm does, but not all sperm are created equal, and some have even developed unique adaptations to get where they're going.

Mr. Andersen explains the Central Dogma of biology. He shows how DNA is transcribed to form mRNA and how mRNA is translated into a protein.

Paul Andersen gives you a brief introduction to the cell membrane. He starts by describing amphipathic nature of a phospholipid and how it assembles into a membrane. He gives an overview of the fluid mosaic model inside cells. He...

Male birds have the largest genital diversity of any class of animals because their sex chromosomes make it easy to pass male-helping mutations down the...

Did you know the moon has a tail? No one did, until 1998, and we've been trying to figure it out ever since.

Today on Crash Course Astronomy, Phil explains comets. Comets are chunks of ice and rock that orbit the Sun. When they get near the Sun the ice turns into gas, forming the long tail, and also releases dust that forms a different tail....

Watch as Mark surprisingly finds then gets slashed and stung by the world's biggest scorpion: the Giant Asian Forest Scorpion! Where will it land on the Brave Wilderness Bite-Sting Index? How will the pain compare to all the other...
