Viewers learn about the history of our knowledge of atoms through the discoveries of eight different scientists: Mendeleev, Democritus, Dalton, Thompson, Schrodinger, Bohr, Rutherford, and Chadwick. 

Since it was accidentally discovered in 1938, polytetrafluoroethylene—otherwise known as Teflon—has made its way into many different products. Watch an informative video that describes the science in making Teflon, and its benefits to...

The leader of the biology gang is known as the nucleus. In the video, learners see the different levels of the hierarchy of life. Scholars explore each level, listening to descriptions and seeing examples of each one. It is the second...

Can you name the man who created the periodic table, committed bigamy, and literally defined Russian vodka? Dmitri Mendeleev did all of these things. The video takes a balanced look at his work and his life. 

This instructional video explains how bonds are formed between different atoms. It discusses valence electrons, charges, electron transfer, and Coulomb attraction. It is the second in a 15-part series.

The video contains a one-question quiz over oxidation numbers, solved with the electron dot structure. It is the seventh in a series of 15 chemistry lessons.

The Rutheford plum pudding model of an atom, as well as the nuclear model, are the subject of a video that also includes an explanation of protons, neutrons, electrons, nucleus, atomic mass, atomic charge, and ions. 

Imagine if scientists today were killed for their thoughts, ideas, and beliefs. And yet, Antoine Lavoisier was beheaded for just those things in 1794. Learn about this fascinating aspect of science along with the contributions of...

Einstein didn't just discover relativity, he proved the existence of atoms in 1905 — more than 110 years ago. Discover how he did it and begin learning about basic chemistry: parts of an atom, atomic mass, atomic number, and how to read...
