Sal does a phenomenal job introducing students to the atom, and the history that goes along with how we understand and view atoms today. Students are introduced to the atomic number, and how elements are organized into the periodic table...

Art forgeries are works of art themselves? How can inspectors tell real art from fake? A video from the a large science playlist explores the techniques practiced by expert forgers and the subtle science behind telling a masterpiece from...

Atoms may make up everything, but what are they made of? The narrator asks patrons at a local park what atoms are in an interview-style video. He then creates an atomic model and adds a neutron to it, opening the discussion to isotopes.

Seeing is believing! But, how can something as tiny as an atom be made visible? Explore the history of the atom with a video from the American Chemical Society's Reactions playlist. Content includes early concepts of the atom, as well as...

How do you prove the existence of something you can't see? For Albert Einstein, a liberal application of math usually did the trick! Physics scholars discover the relationship between atomic size and the motion of larger particles...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...
