Hundreds of meters below the surface of the ocean, Laura Robinson probes the steep slopes of massive undersea mountains. She's on the hunt for thousand-year-old corals that she can test in a nuclear reactor to discover how the ocean...

There aren't many creatures as safe and chill as the humble sea sponge, right? Well, not so fast! It turns out there's a whole family of carnivorous sponges that trap and eat small animals using spines and migrating stomaches!

If you were a jackrabbit in the desert, you'd be glad to stumble across a cactus: the flesh of these plants is a water source for many animals. Known for their spines and succulent stems, cacti of all shapes and sizes have evolved to not...

Join Jessi and friends as they learn about sound waves by making a string phone! Plus, learn how to make your own!

Glaciers might look like just lifeless frozen wastelands, but they are not! There are unique ecosystems hidden inside of them.

In 1816, Europe and North America were plagued by heavy rains, odd-colored snow, famines, strange fogs and very cold weather well into June. Though many people believed it to be the apocalypse, this "year without a summer" was actually...

Mr. Andersen shows you how to use the factor label method to solve complex conversions.

Usually when it's snowing outside, it's really calm, pretty, and fun to play in! But there are certain types of big snowstorms, called blizzards, that can get really windy, wild, and even dangerous!

If you want to improve your wireless internet signal, we've got a few things to keep in mind.

So now that we know what Properties are, how can we use them to figure things out? In this episode of Crash Course Kids, Sabrina uses them to solve the mystery of what she tripped over last night. This first series is based on 5th grade...

Mr. Andersen explains the difference between potential and kinetic gravitational energy. He also uses physics to calculate the energy in various objects.

Mr. Andersen explains the concept of momentum. He also shows you how to solve simple momentum problems. He finally shows you how momentum is both conserved and relative.

There is more than one way to measure the same thing! Jessi and her friend The Giant Squidstravaganza (Squid for short) explore the differences between the Metric System and the Imperial System.

There are all sorts of flying birds, but some of the world's biggest are ones that stick to the ground, like the awesome ostrich!

This video is answering the question of how big are asteroids.

Short video describing acceleration - for middle school

Area is the space inside a 2D shape. The rule for calculating the area of a rectangle is Length X Width.This formula doesn't work for compound shapes (shapes that are made up of two or more basic shapes).If we break down a compound...

This content provides a conceptual understanding of average velocity for a particle moving along a semicircular path. It emphasizes that average velocity is calculated based on displacement (the straight-line distance between start and...

This video demonstrates how to calculate the net work done on an object by multiple forces and explains its relationship to the change in kinetic energy. It walks through a solved physics problem, ideal for understanding work-energy...

A massive earthquake is expected to hit the Pacific Northwest at some point, due to the Cascadia Subduction Zone. This 9.2 magnitude quake could trigger a huge tsunami and destroy major cities like Seattle, collapsing buildings, roads,...

Welcome to our complete high school mathematics tutorial series! Whether you’re a student preparing for exams, a teacher seeking additional resources, or a parent helping your child succeed in math, these videos cover a wide range of...

In this video, we break down the derivation of the continuity equation for ideal fluid flow! Learn how the equation explains why fluid velocity increases as the cross-sectional area of a pipe decreases, such as when you narrow the end of...
