What is Saturn made up of? What are differences between Saturn and Earth? Saturn, Lord of the rings, Part 1

What does our planet look like from space? Most are familiar with the beloved images of the blue marble or pale blue dot -- Earth from 18,000 and 3.7 billion miles away, respectively. But closer to home, within the...

We learned about ideal gases, as well as kinetic molecular theory, which explains the laws that govern ideal gases. But some of the postulates of this theory won't always hold true. When a gas is highly pressurized and/or very cold, it...

This video discusses the historical development of the modern model of the atom. It begins with ancient Greek philosopher Democritus' theory that all matter is comprised of tiny, indivisible particles called atoms. The video then...

This video focuses on the why economists are concerned about Fed Reserve Repos and the effects it might have globally.



Helping you become more knowledgeable about how the world works, our content covers the biggest topics...

This video is about atomic structure and covers the three particles that make up an atom - protons, neutrons, and electrons. The video discusses their properties, such as charge and relative mass, and where they are located within the...

This video explains the basics of sound and how it is produced, transmitted, and perceived. Explore the physics of sound and acoustics. Acoustics is the study of mechanical waves and how they move through gas, liquids, and solids....

Learn the basics about Concentration formula and calculations. How do you calculate the masses of reactants and products from balanced equations? Find out more in this video!

Atmosphere Set: 3. This clip explains the formation of the Earth's auroras.

This is a classic experiment that is frequently referred to when describing quantum phenomena, so we definitely have to go over it a little bit. What happens when you pass a beam of light through a screen with two slits? What about when...

This lecture video explains how sound waves propagate, transfer from air to a solid, and how the human ear works. The video then explains how sound waves interact with solids, including reflection, absorption, and transmission. The video...

The video provides an overview of the structure and function of the lungs, specifically focusing on the alveoli, which are responsible for gas exchange. The video also highlights the negative effects of smoking and other forms of...

Smoke from a candle makes a ""fuse"" that relights it. Parts needed: 1 Candle, 1 Lighter.

LISA Pathfinder, a mission led by ESA (the European Space Agency) that included NASA contributions, successfully demonstrated technologies needed to build a future space-based gravitational wave observatory, a...

How did the field of quantum mechanics come about in the first place? The Rayleigh-Jeans catastrophe, also known as the ultraviolet catastrophe was a prediction by the Rayleigh-Jeans law that a blackbody would radiate infinite amounts of...

At Virginia Polytechnic Institute and State University (VT), Christopher Williams heads the effort to further advance 3-D printing--known among engineers as additive manufacturing--with copper, a widely used conductor in electronics....

This video provides a brief yet intriguing overview of black holes, explaining their formation, characteristics, and different types. It highlights the challenges scientists face in directly observing black holes and explores the...

In this video learn about Collision Theory and find out what is necessary for reactions to take place.

Microwave ovens use radio waves to quickly and efficiently cook food by agitating water molecules and generating heat at the atomic level. The waves can pass through certain materials such as plastic, glass, and ceramic, making heating...

Upon viewing the What is Sound video series, students will be able to do the following: Understand that sound is produced when matter vibrates. Explain that sound energy can travel through air, liquids, and solids, which are generally...

As you go faster, what happens to time and space? What would happen if you could manage to go the speed of light? Astrum Answers!

We've learned a lot about the phenomenon of pressure, so how exactly do we measure it? There are a few different devices that serve different purposes. Barometers measure atmospheric pressure, while manometers measure the pressure of an...

This video explains how thermal energy is transferred by infrared radiation and compares the ability of different material surfaces to absorb and emit this radiation. Examples of different objects and surfaces are given to illustrate...
