Ex 3: Distributive Property to Simplify, Linear Equations, Algebra I
Variables on both sides of the equation are the name of the game in this video, and Sal's easygoing manner and thorough instructions make even complicated algebraic equations look like games. He warms up with two equations to demonstrate...
Khan Academy
Cancer, Cells, MCAT
Learning about apoptosis and how cells can destroy themselves without any external influence is fascinating. Sal creates interest in the vast number of cells and the complexity of the human body. The likelihood of a mutation causing a...
Khan Academy
Solving Quadratic Equations by Completing the Square, Algebra II
"The neat thing about completing the square is that it will always work," Sal explains, "no matter how crazy the problem is." This video provides a basic overview of how to complete the square and provides a good background for both...
Khan Academy
Box-and-Whisker Plots
Elucidating the concept of box-and-whisker plots, Sal explains not only how to generate the diagram but also how to read one. He uses several examples to help young mathematicians become familiar with the format and explains its...
Khan Academy
Difference of Cubes Factoring, Polynomial and Rational Functions, Algebra II
Sal factors and finds the difference between the two cubed terms because this comprehensive presentation would be perfect as homework support or as an independent workstation.

Phase Diagrams, States of Matter and Intermolecular Forces, Chemistry
In his previous videos, Sal showed students how to calculate how much energy is needed to change various amounts of water from state to state when the atmospheric pressure is constant. In this video, he shows students how to use phase...
Khan Academy
Hess's Law and Reaction Enthalpy Change, Chemistry
Sal introduces students to Hess's Law. The law states that a process's energy change is independent of how we get from one state to another. He sets up a series of reactions and solves them to illustrate the principles behind Hess's Law....
Khan Academy
Mitosis, Cells, MCAT
The lecturer starts by emphasizing that the mitotic process is a separate mechanism from cytokinesis—the cytoplasm splitting to become two cells. The video continues by explaining the stages of mitosis in great detail. Each stage is...
Khan Academy
Dividing Mixed Numbers, Fractions, Pre-Algebra
Before Sal can divide a mixed number, he has to rewrite it as an improper fraction. He explains that dividing a fraction is the same as multiplying it by its reciprocal and that you can "cancel out" numbers to make multiplying easier.
