3 Physics Experiments that Changed the World
Physics investigates why the universe behaves the way that it does, and today, Hank tells us about the three physics experiments that he thinks were the most awesome at helping us understand how the universe works.
Crash Course
Electrochemistry: Crash Course Chemistry
Chemistry raised to the power of AWESOME! That's what Hank is talking about today with Electrochemistry. Contained within, Hank discusses electrochemical reactions, half reactions, how batteries work, galvanic cells, voltage, standard...

Electron Configuration
In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law and...

Theory of Everything - What is Matter?
What is matter, anyway? What does it have to do with math? And why aren't you made of Jesus? Delving deeper into the theory of (almost) everything - the Standard Model of particle physics.
Crash Course
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...

Covalent Network Solids
In this video Paul Andersen explains how covalent network solids form elementally (like graphite) or by combining multiple nonmetals (like quartz). Covalent network solids contain elements from the carbon group because they have four...
Bozeman Science
Covalent Bonding
In this video Paul Andersen explains how covalent bonds form between atoms that are sharing electrons. Atoms that have the same electronegativity create nonpolar covalent bonds. The bond energy and bond length can be determined by...

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...
Crash Course
The Periodic Table: Crash Course Chemistry
Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the different...
Crash Course
The History of Atomic Chemistry: Crash Course Chemistry
How did we get here? Well, in terms of Atomic Chemistry, Hank takes us on a tour of the folks that were part of the long chain of other folks who helped us get to these deeper understandings of the world. From Leucippus to Heisenberg to...
TED-Ed
TED-Ed: What can Schrodinger's cat teach us about quantum mechanics? - Josh Samani
The classical physics that we encounter in our everyday, macroscopic world is very different from the quantum physics that governs systems on a much smaller scale (like atoms). One great example of quantum physics' weirdness can be shown...
Bozeman Science
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...
Bozeman Science
Drawing Lewis Dot Diagrams
Mr. Andersen shows you how to draw Lewis Dot Diagrams for atoms and simple molecules.
TED-Ed
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...
Bozeman Science
Atoms and the Periodic Table
Mr. Andersen describes atomic structure and tours the periodic table.
Bozeman Science
Metallic Solids
In this video Paul Andersen explains how metallic solids form when delocalized electrons hold the positive nuclei in an electron sea. This model helps to explain the properties of metals like conductivity, shiny appearance, malleability,...
Bozeman Science
Metallic Bonding
In this video Paul Andersen explains how metallic bonding structure creates the different properties of metals. The electron sea model explains how the positive nuclei are locked into a negative sea of delocalized electrons. This sharing...
Bozeman Science
Chemical Bonds: Covalent vs. Ionic
Mr. Andersen shows you how to determine if a bond is nonpolar covalent, polar covalent, or ionc.
Bozeman Science
Quantum Mechanical Model
In this video Paul Andersen explains how the quantum mechanical model of the atom refined the shell model. Uncertainty of the position of the electron as well as spin forces chemists to create an improved model. In this model the...

How Superconductors Work at the Quantum Level
In 1908, Dutch physicist Heike Onnes figured out how to turn helium gas to liquified helium for the first time. He cooled Mercury and found that all its electrical resistance went away. Electricity in a superconducting wire will continue...

Static electricity: charge
Pupil outcome: I can describe what charges are and how they are transferred between some objects, giving them opposite charges. Key learning points: - Atoms contain positive and negative electric charges. - The particles in atoms with a...

Polyacrylamide Gel Electrophoresis: Protein Electrophoresis Basics
Polyacrylamide gel electrophoresis (PAGE) uses a gel matrix formed by polymerizing acrylamide and bis-acrylamide through free radicals generated by TEMED and APS. This exothermic polymerization forms linear chains cross-linked into a 3D...

Drawing Bohr Models of Atoms and Ions - 3 easy steps!
While While the Bohr model of the atom is not the most accurate model we have today, it can help up show a lot of valuable information about the atom. Bohr models can show the protons and neutrons in the nucleus along with the number of...
