Part three of this four-part series on the origins of the universe describes the radiation that can be heard in static radio signals and the other amazing remnants left today that were around at the time the universe was born. Stars,...

How much does your class know about subatomic particles? Module 13 in a 14-part series tests their knowledge of how to determine an atom's number of protons, neutrons, and electrons when given the atomic number and the mass...

Looking for a great way to see what young chemists know about atomic structure? In the 14th and final installment in the states of matter series, learners put their skills to the test. The four-part question covers placement of...

I blew up my chemistry experiment. Oxidants happen. The ninth video in the series walks through the steps on how to solve one problem by finding oxidation numbers using an electron dot structure.

Want to hear a joke about element 116? Uuh ... Here is a video that explains how to find the formal charge of a molecule using its covalent electron distribution. It focuses on electron dot structure and dividing the molecule into...

Part of a longer video created by Disney, this segment opens with a history of the telescope and microscope. This old-fashioned video is a sufficient introduction to the topic of atoms. The animations are antiquated, but they are still...

Everything is made of Atoms and the number of electrons and neutrons an atom has determine what form it will take. This class dresses up as the components of an atom to demonstrate the Atomic Model. Great for kinesthetic and visual...

Part one of this short two-part series begins with a review of Einstein's theories and what they mean to the world as we know it. This clip delves into the "Beyond Einstein" program which NASA created to further Einstein's theories. This...

Drawings on an interactive whiteboard are used to introduce the basic structure of an atom. Technically, the model drawn is inaccurate, as three electrons are shown on the innermost orbital. Electron orbitals are not the intent of the...

How are gases like liquids; how are they different? This clip demonstrates the state of matter called gas. We find out how the properties of gas are similar and different to the properties of liquid. An experimental demonstration and...

Chemguy uses diagrams on his whiteboard to describe the structure of an atom. In a second segment, he explains what an isotope is with an example. That is all there is to this presentation. Its brevity allows you to include it as a link...

A materials science and engineering professor, Dr. Chris Muhlstein of Penn State University, explains how to rearrange atoms without touching them with your hands. [3:06]

A video lecture explaining elements and their differing properties. Also discussed is how elements relate to atoms and the particles that make up an atom. [13:08]

A video showing the mathematical description of the uncertainty principle to associate it with the momentum of electrons to solve for the position of the electron. [10:17]

Video tutorial explains the difference between atomic weight and atomic mass in chemistry, and how it compares to the physics definitions of weight and mass. [8:53]

Video tutorial presents an introduction to the concept of a mole as a number. [9:43]
