American Government is designed to meet the scope and sequence requirements of the single-semester American government course. This title includes innovative features designed to enhance student learning, including Insider Perspective features and a Get Connected Module that shows students how they can get engaged in the political process. The book provides an important opportunity for students to learn the core concepts of American government and understand how those concepts apply to their lives and the world around them. American Government includes updated information on the 2016 presidential election.Senior Contributing AuthorsGlen Krutz (Content Lead), University of OklahomaSylvie Waskiewicz, PhD (Lead Editor)

Novel representations and diverse perspectives can reveal new insights into complex systems, and can support rich understandings of the world. In this activity, students will identify and analyze the choices artists and scientists make when creating representations of living or non-living natural objects. This process will help students recognize the potential and place for their own articulation of how the world works. After drawing from nature, students will reflect on the process of representing information, then compare their drawings with that of a 16th-century artist. Students will consider what is included and what is excluded, and hypothesize about larger contexts and systems.

This subject investigates the special relation of women to several musical folk traditions in the British Isles and North America. Throughout, we will be examining the implications of gender in the creation, transmission, and performance of music. Because virtually all societies operate to some extent on a gendered division of labor (and of expressive roles) the music of these societies is marked by the gendering of musical repertoires, traditions of instrumentation, performance settings, and styles. This seminar will examine the gendered dimensions of the music -- the song texts, the performance styles, processes of dissemination (collection, literary representation) and issues of historiography -- with respect to selected traditions within the folk musics of North America and the British Isles, with the aim of analyzing the special contributions of women to these traditions. In addition to telling stories about women's musical lives, and studying elements of female identity and subjectivity in song texts and music, we will investigate the ways in which women's work and women's cultural roles have affected the folk traditions of these several countries.

This lesson explores several strands of the musical "DNA" that make up the beat of popular music. Looking to the past, this lesson asks what it means to call music "Afro-Cuban" "Afro-Caribbean," or more broadly, "African-American." Students will use Soundbreakingclips of Santana and Beyonce and the Soundbreaking Rhythmic Layers TechTools to locate in American popular music influences stemming from the African-American church, Latin America and West Africa. Students will then explore the ways "the beat" of this music has, to some listeners, been perceived as "dangerous" while, for others, it is believed that music has been able to challenge obstacles of racism and segregation, bringing people from varied ethnic groups and lifestyles together in ways that words and laws could not.

This interactive Flash animation allows students to explore size estimation in one, two and three dimensions. Multiple levels of difficulty allow for progressive skill improvement. In the simplest level, users estimate the number of small line segments that can fit into a larger line segment. Intermediate and advanced levels offer feature games that explore area of rectangles and circles, and volume of spheres and cubes. Related lesson plans and student guides are available for middle school and high school classroom instruction. Editor's Note: When the linear dimensions of an object change by some factor, its area and volume change disproportionately: area in proportion to the square of the factor and volume in proportion to its cube. This concept is the subject of entrenched misconception among many adults. This game-like simulation allows kids to use spatial reasoning, rather than formulas, to construct geometric sense of area and volume. This is part of a larger collection developed by the Physics Education Technology project (PhET).
