Beginning a series based on The Official SAT Study Guide(first edition), the speaker (Sal) deftly demonstrates how to work through the types of problems typically seen on the SAT. He assumes that the reader is also working from the...

Here is a recipe for a practical cross-curricular lesson! Cover unit conversions and ratios for math, the periodic table of elements for science, the difference between sodium and salt and its relation to high blood pressure for...

How many ways can you graph a quadratic? The video shows two approaches to graphing a quadratic expression that is initially in standard form. The first method finds the vertex using -b/2a. The second approach is to find (h,k). 

The process requires the combination of several concepts. A video shows how individuals need several concepts to add rational expressions. Pupils must remember they need to find common denominators, combine like terms, and use the...

Demonstrate how to use a box and whisker plot to place a line of best fit accurately with an educational video. It begins with a review of box and whisker and line of best fit, and then uses an application problem to describe the...

Sal spends most of this video explaining the Mean Value Theorem in a very intuitive way. He follows this with a concrete example of finding the value of a function on a closed interval where the slope is the same as the average slope of...

Discover the transition from circular orbit theories to elliptical orbits. An episode of a video series on astronomy models the different elliptical shapes of the orbits of the planets in the solar systems. Using string, the presenter...

Scientists and engineers in every field use scientific notation. The Socratica video explains what scientific notation is and why people use it. Then, it offers examples of how to convert a number into and out of scientific notation....

If you know how much carbon dioxide you produce in one breath, can you figure out how much you produce in one month? Socratica helps solve multi-step unit conversion problems. The video walks through how to set up these challenges and...

Orbital velocity of planets change. Kepler's Second Law of Motion attempts to explain and predict the change in velocity. Scholars learn how to apply this law as they watch the video lesson.
