Investigate various approaches for summarizing variation in data, and learn how dividing data into groups can help provide other types of answers to statistical questions. Understand numerical and graphic representations of the minimum, the maximum, the median, and quartiles. Learn how to create a box plot.
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
Investigate symmetry, one of the most important ideas in mathematics. Explore geometric notions of symmetry by creating designs and examining their properties. Investigate line symmetry and rotation symmetry; then learn about frieze patterns.

Learn that area is a measure of how much surface is covered. Explore the relationship between the size of the unit used and the resulting measurement. Find the area of irregular shapes by counting squares or subdividing the figure into sections. Learn how to approximate the area more accurately by using smaller and smaller units. Relate this counting approach to the standard area formulas for triangles, trapezoids, and parallelograms.
Examine visual methods for finding least common multiples and greatest common factors, including Venn diagram models and area models. Explore prime numbers. Learn to locate prime numbers on a number grid and to determine whether very large numbers are prime.
Dave tours historic locations in Philadelphia recalling battles of the American Revolution and the lives of the Founding Fathers who attended the Constitutional Conventions held there. He spends some time at Franklin House where he reviews the biography of the great statesmen and inventor. Locations, such as the American Philosophical Society, Declaration House, and Carpenter's Hall bring to mind the writing of the Declaration of Independence and the American Constitution, documents whose common sense approach to freedom and liberty is extolled throughout the episode. Dave also recalls the history of the Liberty Bell, the design of the Great Seal, and the establishment of the American bald eagle as the symbol of the United States and its freedoms.
Investigate the difference between a count and a measure, and examine essential ideas such as unit iteration, partitioning, and the compensatory principle. Learn about the many uses of ratio in measurement and how scale models help us understand relative sizes. Investigate the constant of proportionality in isosceles right triangles, and learn about precision and accuracy in measurement.
Connections can be physical, as with bridges, or immaterial, as with friendships. Both types of connections can be understood using the same mathematical framework called network theory, or graph theory, which is a way to abstract and quantify the notion of connectivity. This unit looks at how this branch of mathematics provides insights into extremely complicated networks such as ecosystems.
I Choose My Future, a captivating presentation and video series, provides viewers with comprehensive, straightforward insight into how substance abuse impacts the individual, their families, and society.

What tools do world historians use in the study of history? This unit begins the study of world history by examining its use of geographical and chronological frameworks: how they have shaped the understanding of world history and have been used to chart the past.
Rome's civil engineering contributed as much to the empire as did its weapons.n
This program on physics is the last of five programs in the science section of the GED Connection series, which helps prepare students for the GED exam. Physics is the study of forces that move things. Matter is anything that takes up space or has a mass. The program features guests of various disciplines who explain specific applications of physics concepts. The first segment uses the physics of roller coasters to explain the three laws of motion. Energy is defined as the ability to do work; work involves moving something by using a force at a distance. Potential and kinetic energy are discussed. There are three "Test Connection" segments where the host underscores previous lessons dealing with the three laws of motion, the relationship between space flight and the laws of thermodynamics involving heat; and how to apply information about sound waves in helping students to read charts on the GED exam and beyond. A segment called "The Science of Sound" presents a physics teacher who also sings about such physics themes as the mechanics of sound waves. Also covered are distinctions between electricity and magnetism, as well as current and voltage. The electromagnetic spectrum consists of waves traveling at the speed of light, including visible light. Another feature is the use of electromagnetic waves by MRI technician.
