Explore what can be measured and what it means to measure. Identify measurable properties such as weight, surface area, and volume, and discuss which metric units are more appropriate for measuring these properties. Refine your use of precision instruments, and learn about alternate methods such as displacement. Explore approximation techniques, and reason about how to make better approximations.
Systems of synchronization occur throughout the animate and inanimate world. The regular beating of the human heart, the swaying and near collapse of the Millennium Bridge, the simultaneous flashing of gangs of fireflies in Southeast Asia: these varied phenomena all share the property of spontaneous synchronization. This unit shows how synchronization can be analyzed, studied, and modeled via the mathematics of differential equations, an outgrowth of calculus, and the application of these ideas toward understanding the workings of the heart.
Continue examining the number line and the relationships among sets of numbers that make up the real number system. Explore which operations and properties hold true for each of the sets. Consider the magnitude of these infinite sets and discover that infinity comes in more than one size. Examine place value and the significance of zero in a place value system.

Explore the basics of geometric thinking using rich visualization problems and mathematical language. Use your intuition and visual tools for geometric construction. Reflect on the basic objects of geometry and their representation.
Consider statistics as a problem-solving process and examine its four components: asking questions, collecting appropriate data, analyzing the data, and interpreting the results. This session investigates the nature of data and its potential sources of variation. Variables, bias, and random sampling are introduced.
Examine the relationships between area and perimeter when one measure is fixed. Determine which shapes maximize area while minimizing perimeter, and vice versa. Explore the proportional relationship between surface area and volume. Construct open-box containers, and use graphs to approximate the dimensions of the resulting rectangular prism that holds the maximum volume.
The conventional notion of dimension consists of three degrees of freedom: length, width, and height, each of which is a quantity that can be measured independently of the others. Many mathematical objects, however, require more

How do ideas change the world? This unit traces the impact of European Enlightenment ideals in the American and Haitian revolutions and in South America. It also examines the revitalization of Islam expressed in the Wahhabi movement as it spread from the Arabian peninsula to Africa and Asia.
Public education and mass communications created a new political life and leisure time.n
This, the first of five science programs lays the foundation for the science track. It explains the four main areas of science that will be covered on the GED test and in the next four episodes (life science, earth and space science, chemistry and physics). The host explains the basic format of the test - the fact that there are 50 multiple choices questions based on passages that test takers read. Throughout the program sample questions are reviewed, the correct answers are provided and an explanation is given for why the other answers are incorrect. The program includes commentary from the Executive Director of the GED Testing Service who provides insight into how the new test differs from the previous version and offers suggestions for taking the test (such as reading carefully and learning to recognize what is being asked). The program also features commentary from researchers, teachers and others in biology, chemistry, and other fields who describe how they use science and their professional and everyday lives. The GED hotline phone number (1-800-626-9433) and the LiteracyLink Web site (www.pbs.org/literacy) are both mentioned in the program (and on screen) as resources for additional information.
