This short video and interactive assessment activity is designed to teach fourth graders about visual differences in length (english units).

This course is an invitation to German film-making since the end of the Second World War. We investigate how German cinema captured the atmosphere of the immediate post-war years and discuss extensively major works of the "New German Cinema" of the Sixties and Seventies. We also look at examples of East Germany's film production and finally observe the very different roads German cinema has been taking from the 1990's into the present.

This short video and interactive assessment activity is designed to teach fifth graders about visual objects: comparing length.

Students make simple spectroscopes (prisms) to look at different light sources. The spectroscopes allow students to see differing spectral distributions of different light sources. Students also shine a light source through different materials with varying properties and compare the differences.

The organization of the mammalian visual system and the manner in which shape, color, texture, motion, and depth are processed. Alternate years.

This short video and interactive assessment activity is designed to teach fourth graders about visually comparing weight and balancing a scale (metric units).

This short video and interactive assessment activity is designed to teach fourth graders about visually finding weights and calculate totals (metric units).

This short video and interactive assessment activity is designed to teach fourth graders about visually finding capacity (metric units).

The purpose of this textbook is to help learners develop best practices in vital sign measurement. Using a multi-media approach, it will provide opportunities to read about, observe, practice, and test vital sign measurement.

For the singer and/or pianist interested in collaborative study of solo vocal performance. Historical study of the repertoire includes listening assignments of representative French, German, Italian, and English works as sung by noted vocal artists of the genre. Topics include diction as facilitated by the study of the International Phonetic Alphabet; performance and audition techniques; and study of body awareness and alignment through the Alexander Technique and yoga.

Vocal Techniques, the course title used at many institutions, is essentially a voice class for instrumentalists, and is a required course for instrumental music education majors seeking all-level certification. Students take at least one Vocal Techniques course to learn proper singing technique along with basic pedagogy and can include teaching techniques as they apply to adolescent singers. The focus of the course is the development of the individual singing voice. This includes breathing, tone production, articulation, musicality and textual expression and understanding. Students also develop confidence in front of groups, improve their general vocal quality, and learn that a healthy voice serves them well in the general and performance classroom.

This lesson helps students "hear" some of the diverse colonial voices that, in the course of time and under the pressure of novel ideas and events, contributed to the American Revolution. Students analyze a variety of primary documents illustrating the diversity of religious, political, social, and economic motives behind competing perspectives on questions of independence and rebellion.

Students learn about the causes, composition and types of volcanoes. They begin with an overview of the Earth's interior and how volcanoes form. Once students know about how a volcano functions, they learn how engineers predict eruptions. In a class demonstration, students watch and measure a mock volcanic eruption and observe the phases of an eruption, seeing how a volcano gets its shape and provides us with clues to predict a blast.

Challenged with a hypothetical engineering work situation in which they need to figure out the volume and surface area of a nuclear power plant’s cooling tower (a hyperbolic shape), students learn to calculate the volume of complex solids that can be classified as solids of revolution or solids with known cross sections. These objects of complex shape defy standard procedures to compute volumes. Even calculus techniques depend on the ability to perform multiple measurements of the objects or find functional descriptions of their edges. During both guided and independent practice, students use (free GeoGebra) geometry software, a photograph of the object, a known dimension of it, a spreadsheet application and integral calculus techniques to calculate the volume of complex shape solids within a margin of error of less than 5%—an approach that can be used to compute the volumes of big or small objects. This activity is suitable for the end of the second semester of AP Calculus classes, serving as a major grade for the last six-week period, with students’ project results presentation grades used as the second semester final test.

Students research archival material to examine nineteenth and early twentieth century arguments for and against women's suffrage.

This problem is the fifth in a series of seven about ratios. In the first problem students define the simple ratios that exist among the three candidates. It opens an opportunity to introduce unit rates. The subsequent problems are more complex. In the second problem, students apply their understanding of ratios to combine two pools of voters to determine a new ratio. In the third problem, students apply a known ratio to a new, larger pool of voters to determine the number of votes that would be garnered.

This is the sixth problem in a series of seven that use the context of a classroom election. While it still deals with simple ratios and easily managed numbers, the mathematics surrounding the ratios are increasingly complex.

This is the last problem of seven in a series about ratios set in the context of a classroom election. Since the number of voters is not known, the problem is quite abstract and requires a deep understanding of ratios and their relationship to fractions.

This is the first and most basic problem in a series of seven problems, all set in the context of a classroom election. Every problem requires students to understand what ratios are and apply them in a context. The problems build in complexity and can be used to highlight the multiple ways that one can reason about a context involving ratios.

This is the second in a series of tasks that are set in the context of a classroom election. It requires students to understand what ratios are and apply them in a context. The simple version of this question just asked how many votes each gets. This has the extra step of asking for the difference between the votes.
