Sal crafts a demonstration around one of his "most misspelled words" - logarithms - in this thorough and understandable video. He defines a logarithm before using several examples to illustrate his point. Sal makes learning this concept...

Logarithms and exponents go together like multiplication and division. A video lesson demonstrates solving exponential equations both graphically and using logarithms. Supplemental materials give learners an option to practice what...

You can't just do any old thing with a logarithm. You need a property to back you up. Pupils learn the properties of logarithms and how they relate to exponent properties in a video presentation. They then use the provided practice...

There is no rhythm like the logarithm. A complete lesson on graphing logarithm highlights the inverse relationship between exponential and logarithmic functions. A guided notes document and practice problem accompany the video presentation.

Keep on rolling with a lesson on logarithms. A video presentation introduces the definition of logarithms, the properties of them, and then how to use logarithms to solve simple exponential equations. The lesson is a first in a series of...

Linear scales are the standard that most graphs and data use. Converting data to a logarithmic scale can be tricky, but a video presentation thoroughly describes the process. Using visual imagery and specific examples, the lesson...

What is pH and where does it come from? Science superstars take their understanding of acids and bases to another level using a video from JFR Science. The narrator builds on prior knowledge to show viewers how to use what they already...

Aren't all acids strong? Dispel the myth with a video from JFR Science. Viewers learn general types of strong and weak acids, what the dissociation constant is, and the behavior of strong versus weak acids with bases and water.

What makes one acid stronger than another? Pupils peruse the property of pH through a video from the JFR Science playlist. The narrator explains what is meant by a neutral pH, what that looks like from a chemical standpoint, and how...

It is only natural to take the derivative of a logarithmic function with a complex argument. The 21st installment in a series of 31 provides an example of taking the derivative of a natural logarithmic function. First simplifying the...

Use this trick to find the derivative of x raised to the x power. The video shows how to find a complicated derivative by rewriting the function using properties of logarithms. After rewriting the function, the derivative is simply...

Is your smartphone really doing its best work when it comes to color? The narrator describes technology's lazy approach to recreating colors in an insightful video. Science scholars discover how digital cameras store...

Get to the point! An absorbing video introduces some new notation for exponents, logarithms, and radicals using the three points of a triangle. It explains how to use this notation and how it is more intuitive than the accepted notation...

An informative video provides a definition for an acid, where it falls on the pH scale, and how individuals test for them. It uses many examples with chemical equations.

Studying acids and bases can be basic. Over the course of four short videos, an instructor explains the pH scale. Viewers observe a demonstration and watch the instructor solve two quiz questions in detail. 

The instructor shows how logarithms of base e can be written as using the natural logarithm notation, abbreviated ln.

This video shows how to convert an equation in exponential form to logarithmic form. The example shown uses base e, and it is converted to an equation using a natural logarithm.

Logarithms can be a little tricky and if you'd like to use a calculator you'll need to use a formula to change the given logarithm into base ten. This tutorial defines the formula, uses it to change a logarithm to base ten, then how to...

You don't want to risk breaking the Laws of Logarithms! The video instructor explains the steps to using laws to condense a logarithmic expression and evaluate the result. The lesson is a continuation of videos in a series of 29.

A graph of bacteria growth is shown and explained in this one-minute clip. Help your young scientists learn how to read scientific graphs by showing them this video.

Demonstrates how to convert a logarithmic equation to an exponential equation. [1:27]

Explains what a logarithm is and the relationship between logarithms and exponents. Practice problems available. [9:48]

Demonstrates how to apply the logarithm property regarding the sum of logarithms with the same base to simplify a logarithmic expression. [5:04]

This video demonstrates how to apply the property that division inside a log can be turned into subtraction and the logarithm of a power property to simplify a given logarithmic expression. [2:10]
