A build up of static electricity is usually harmless, resulting in only small shocks. But in some cases it can be deadly. Discover the danger static electricity poses for helicopters and their crew. Physics - Electricity And Circuits -...

Water is added to dry and bent matchsticks to let us see capillary action at work. The wood absorbs the water causing the matchsticks to straighten. Biology - Plants - Learning Points. Water is a polar molecule because the electrons are...

We use a Van de Graaff generator to investigate static electricity. The generator is turned on and we see a spark move between the two domes. We then place a wig on the main dome and see the hair rise as the charge builds and the hairs...

Dr. Forrester defines the terms: atoms, protons, electrons, and neutrons. She explains that atoms are made up of protons, electrons and neutrons. She also teaches that all electricity comes from the electrically charged particles.

Let's learn how nuclear fusion powers the sun!

Static Charge | Electricity | Physics | FuseSchool Have you ever had your hair stand on end after combing it, or after you have rubbed a rubber balloon against it? This video will look at the physics behind static electricity. It might...

It may seem counterintuitive, but draining the battery to 0 to 1% before recharging it again, is not a good practice. One simple hack to improve your battery life (for Li-ion batteries) is to use the 80:20 rule. Charge your battery to...

Lotus uses her birthday present to uncover another secret about Mark Brent - he’s radioactive! This lesson will introduce the different types of field forces.

Definitions included: force, field force, mass, weight, electric force,...

In this video, we discuss the mechanisms by which proteins are targeted to the nucleus (import) and moved from the nucleus to the cytoplasm (export). Collectively, nucleocytoplasmic transport is regulated by the nuclear pore complex and...

Learn the basics about Testing for positive ions - part 2. Find out more in this video!

What is an atom | Matter | Physics | FuseSchool Atoms are tiny particles that are so small they are not possible to see with the naked eye, and are only barely possible to make out with the most powerful microscopes. Everything that...

The video explains the fundamental concepts of mass number, atomic number, and isotopes. It begins by presenting a diagram of an atom and the three particles contained within it - neutrons, protons, and electrons - and their charges. The...

Ready for action? Time to get your neurons firing with some action potential. If you thought resting potential was tough to understand, it seems like action potential is that much more difficult. However, thanks to Alie Astrocyte, we...

I can see clearly now the rain is gone...oh, and because I know all about the VISUAL SYSTEM! Going beyond the physics of the eye and how light works, how much do you know about how visual information gets sent to the brain? Alie...

Semiconductors are the essential components that allow electricity to flow and regulate the flow of electrical energy in all electronic devices. They are materials that sit between conductors and insulators, enabling the controlled...

How a superconductor works. Everything from the physics and some of the history as well. Superconductors were discovered in 1911 by Heike Kamerlingh Onnes. It was discovered because it was made possible to liquefy helium which produced...

What's the deal with electricity? Benjamin Franklin flies a kite one day and then all of a sudden you can charge your phone? There's a gap in conceptual understanding! Let's figure out what electricity is, exactly, and how it works.

Electrolysis is electrical current flow through a liquid which causes chemical changes. The liquid can be a molten ionic compound or aqueous solution. The liquid will contain free-flowing positive ions and negative ions. The positive...

The program offers a brief review of ions. Students will learn what determines the charge on an ion and how ionic bonds are formed. Viewers will come to understand that ionic bonds form due to electrostatic attraction between two ions...
