A watershed and its features are very important parts of a region's water supply system. It can also be a powerful predictor of the quality of life in this region. This segment of a WPSU documentary Liquid Assets describes how a watershed is formed.

What is it that distinguishes a living organism from a nonliving object? This collection of images presents examples that aren't as clear-cut as one might think, enticing students to question the meaning of life.

These questions test knowledge of the definition of a logarithm, domain and range of logarithmic functions, and properties of logarithms. Questions are true/false and multiple-choice; solutions are provided.

Students are introduced to a unique fluid ferrofluids the shape of which can be influenced by magnetic fields. This activity supplements traditional magnetism activities and offers comparisons between large-scale materials and nanomaterials.Students are introduced to the concepts of magnetism, surfactants and nanotechnology by relating movie magic to practical science. Students observe ferrofluid properties as a stand-alone fluid and under an imposed magnetic field. They learn about the components of ferrofluids and their functionality as they create shapes using magnetically controlled ferrofluids and create their masterpieces.

This pathway explores the essential concepts of magnets and magnetic fields. The relationship between magnets and the fields they produce is explained, as well as some of the contemporary applications of magnetism in medical diagnostics and quantum mechanics. Problems are provided to check for understanding.

In this fun, engaging activity, students are introduced to a unique type of fluid ferrofluids whose shape can be influenced by magnetic fields! Students act as materials engineers and create their own ferrofluids. They are challenged to make magnetic ink out of ferrofluids and test their creations to see if they work. Concurrently, they learn more about magnetism, surfactants and nanotechnology. As they observe fluid properties as a standalone-fluid and under an imposed magnetic field, they come to understand the components of ferrofluids and their functionality.

The tutorial examines the domain of functions. Students learn about the mathematics concept through examples with detailed solutions.

Here is a site that clearly and thoroughly explains functions and function notation. There are example problems solved, problems for the student to attempt, and answers to the student problems. Point this site out to students who have been absent or who need additional instruction on this or many other topics.
