Compare and contrast folktales, myths, and fables in an interactive eBook. The interactive is broken up into three topics: myths, fables, and folktales. Each section includes a reading passage and a guided lesson on the theme, topic, and...

See calculus to the end. The eBook is the last of a three-volume series covering college-level calculus topics. Scholars begin with parametric equations and polar coordinates before moving to vectors, finally ending with multi-variable...

Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

What could be more real life than a biology course? Mt. Hood Community College offers a complete biology textbook with an emphasis on genetics. Topics range from DNA replication to biotechnology and inheritance patterns.

Violet is making a pattern of colored cereal for a necklace but keeps eating some until only one color is left. Includes audio narration in 16 additional languages with text in English.

Students investigate the underlying causes of two-point source interference pattern. They also discover that the spatial separation between the antinodal and nodal lines in the pattern is related to the wavelength of the waves.

Students examine the findings of Thomas Young's light experiment, which showed that an interference pattern results when light from two sources meets up while traveling through the same medium.

This lesson focuses on wallpaper groups. While there are infinitely many possible patterns, they all have one of just 17 different symmetry groups. These are called the Wallpaper Groups. Every wallpaper group is defined by a combination...

Mathematicians in ancient Greece were amazed by mathematical patterns, and wanted to explore and explain them. They began to study mathematics just "for fun" without a specific application in mind. One of these mathematicians, Thales of...

A guitar string has a number of frequencies at which it will naturally vibrate. These natural frequencies are known as the harmonics of the guitar string. Students work through several example problems.

After looking at a representative two-point source interference pattern with accompanying order numbers, students investigate the rationale behind the numbering system, and develop some mathematical equations that relate the features of...

This lesson focuses on Pascal's Triangle, a number pyramid in which every cell is the sum of the two cells directly above. It contains all binomial coefficients, as well as many other number sequences and patterns.

This lesson focuses on Fibonacci numbers, a pattern based on the sum of the two previous numbers. It offers examples and practice exercises using some form of Fibonacci numbers.
