TED: Climate change isn't a distant threat -- it's our reality | Selina Neirok Leem
Every year, ocean levels rise and high tides flood the low-lying Marshall Islands in the Pacific, destroying homes, salinating water supplies and disrupting livelihoods. In a stirring poem and talk, youth climate warrior Selina Neirok...

TED-Ed: How to squeeze electricity out of crystals - Ashwini Bharathula
It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini...

Traveling Waves: Crash Course Physics
Waves are cool. The more we learn about waves, the more we learn about a lot of things in physics. Everything from earthquakes to music! Ropes can tell us a lot about how traveling waves work so, in this episode of Crash Course Physics,...

Photons
In this video Paul Andersen explains how light travels in photons which can be described as both particles and waves. Einstein showed that photons can be described as particles using the photoelectric effect to show that the energy of a...

Sound Waves
Mr. Andersen explains how sound waves are created and perceived. A brief discussion of pitch and loudness are included. A generated sound of varying pitches is also included.

TED-Ed: What is the Heisenberg Uncertainty Principle? - Chad Orzel
The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time....

Quantum Tunneling Takes a Surprisingly Long Time
Quantum tunneling happens when a particle seemingly teleports across a barrier. But despite how instantaneous this event sounds, recent research suggests that it doesn’t happen nearly as fast as you might think.

How Do Noise-Canceling Headphones Work?
You're on a flight, and the drone of the engines is getting on your nerves, so you pop on a pair of noise-canceling headphones, and sweet, blessed silence descends. But those headphones aren't just muffling the sound -- they're actually...

Standing Waves
In this video Paul Andersen explains how standing waves are created through the reflection and interference of traveling waves. Destructive interference creates areas of no movement called nodes. Constructive interference creates areas...

TED-Ed: Can loud music damage your hearing? | Heather Malyuk
After a concert, you find it difficult to hear your friend rave about the show. It sounds like they're speaking from across the room, and it's tough to make out their voice over the ringing in your ears. But, by the next morning, the...

TED-Ed: The science of hearing - Douglas L. Oliver
The ability to recognize sounds and identify their location is possible thanks to the auditory system. That's comprised of two main parts: the ear, and the brain. The ear's task is to convert sound energy into neural signals; the brain's...

Doppler Effect
In this video Paul Andersen explains how the perceived frequency of a source depends on the motion of both the source and the observer. As a source approaches an observer the frequency will increase and as it moves away it will decrease....

Wave Period and Frequency
In this video Paul Andersen explains how the period is the time between wave and the frequency is the number of waves per second. Period is measured in seconds and frequency is measured in Hertz. Wave period and wave frequency are...
