Viewers watch while the narrator explains limiting reactions through the familiar example of a recipe. He then describes why it is necessary to use moles to solve these problems rather than just relying on diagrams. The video ends...

CH2O is not the formula for seawater, and this resource explains why. The video models how to write the chemical formula when given the chemical name in both covalent an ionic forms. 

Using impactful visuals and chemical equations, this video describes how to balance chemical equations. It uses examples that are common to the classroom such as methane burning in a Bunsen burner. 

After discovering plutonium, Glenn Seaborg was given the opportunity to determine its periodic symbol. Rather than going with the obvious Pl, he went with Pu as a joke. The designation was approved and is now on every periodic...

A chemistry walks  viewers through non-polar covalent, polar covalent, and ionic bonds and how to determine the type of specific chemical bonds. 

The major groups on the periodic table and their general properties based on their electrons are the focus of a video that also explains why the table is drawn in two parts and which elements are crucial to life. 

In 1924, Bose and Einstein predicted a fifth state of matter. The prediction proved to be true in 1995 and is referred to as the Bose-Einstein condensation. This video discusses the concept of matter, all five states of matter, and what...

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. 

Learners investigate the relationship of position with respect to time in a graphical situation and develop an understanding of the slope related to the object in motion. They then use that understanding to create a velocity versus time...
