Velocity Time Graphs, Acceleration & Position Time Graphs - Physics
By The Organic Chemistry Tutor
This physics video tutorial provides a basic introduction into motion graphs such as position time graphs, velocity time graphs, and acceleration time graphs. It explains how to use area and slope to calculate the velocity, acceleration, displacement, and whether if the particle is speeding up or slowing down. It also explains how to determine if the velocity is increasing or if the acceleration is positive.
pH of Weak Acids and Bases - Percent Ionization - Ka & Kb
By The Organic Chemistry Tutor
This chemistry video explains how to calculate the pH of a weak acid and a weak base. It explains how to calculate the percent ionization of a weak acid using the acid dissociation constant Ka.
Capacitors - Basic Introduction - Physics
By The Organic Chemistry Tutor
This physics tutorial provides a basic introduction into capacitors. It explains the concept of capacitance and how it works including the equations and formulas you need to solve homework problems. The full version of this video contains plenty of examples and practice problems for you to work on.
Buffer Solutions
By The Organic Chemistry Tutor
This chemistry video tutorial explains how to calculate the pH of a buffer solution using the henderson hasselbalch equation. It explains the concept, components, and function of a buffer solution. A buffer solution consist of a weak acid and its conjugate weak base counterpart. It's purpose is to maintain a relatively constant pH value. This video discusses the relationship between the pH and pKa values with the relative amounts of weak acid and weak base components in the buffer solution. This video contains plenty of examples and practice problems.

2011 Roundtable at Stanford: Redefining K-12 Education in America
By Lumos Learning
October 22, 2011 - Designing an education that truly builds the necessary skills for today's enormously diverse student population is not easy. But it's the key to opportunity for our citizens, economic vitality for our nation, and to assuring the U.S. remains a world leader. There is hope: innovations and innovators that challenge the status quo; research to help us understand how to move the education needle; a virtual army of reformers experimenting with new ways to teach, learn, and run our public schools.
