What Physics Teachers Get Wrong About Tides!
We all know tides have something to do with gravity from the Moon and Sun, but if gravity affects the motion of all objects equally, then how come oceans have large tides while other bodies of water don't? It's because your mental...

Why Do My Ears Pop?
We’ve all experienced it, that annoying pressure in our head when we’re flying in a plane or a storm front comes in, then it pops! Find out how this popping happens and things to avoid so you don’t harm your ears.
Crash Course
Real Gases: Crash Course Chemistry
Hank bursts our ideal gas law bubble, er, balloon, and brings us back to reality, explaining how the constants in the gas law aren't all that constant; how the ideal gas law we've spent the past two weeks with has to be corrected for...

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...
