TED-ED: The strengths and weaknesses of acids and bases - George Zaidan and Charles Morton
Vinegar may have a powerful smell, but did you know it's actually a weak acid? In the chemical economy, acids actively give away their protons while bases actively collect them -- but some more aggressively than others. George Zaidan and...

Electromagnetism - Electrostatic Force: The Four Fundamental Forces of Physics #4a
Hank reaches the fourth and final of the four fundamental interactions in physics: electromagnetism. In this part, he teaches us about the electrostatic force, which builds up a charge in an object and can travel in the form of an...

The Bohr Atom
In this video Paul Andersen describes the major parts of an atom and explains how the Bohr Model more accurately represents the location of electrons around the nucleus. Niels Bohr refined the Rutherford model to account for spectra.

Nuclear Chemistry: Crash Course Chemistry
In this episode, Hank welcomes you to the new age, to the new age, welcome to the new age. Here he'll talk about transmutation among elements, isotopes, calculating half-life, radioactive decay, and spontaneous fission. -- Table of...
Crash Course
pH and pOH: Crash Course Chemistry
In this episode, Hank goes over Reversible Reactions, the water dissociation constant, what pH and pOH actually mean, Acids, Bases, and Neutral Substances as well as the not-so-terrifying Logarithms, strong acids, weak acids, and how to...

TED-Ed: Radioactivity: Expect the unexpected - Steve Weatherell
Neutrons don't change into protons. Except, sometimes, they do. Radioactivity is the process under which the nucleus can change spontaneously from one element to another. Steve Weatherell suggests that we acknowledge both the usefulness...

Cellular Respiration
Paul Andersen covers the processes of aerobic and anaerobic cellular respiration. He starts with a brief description of the two processes. He then describes the important parts of the mitochondria. He explains how energy is transferred...

TED-Ed: Pedro Brugarolas: Why do hospitals have particle accelerators?
Is there a way to detect diseases like cancer and Alzheimer's before they advance too far? Doctors are using injected radioactive drugs that circulate through the body and act as a beacon for PET scanners. These diagnostic tools can...
