Students will listen to and analyze music of Afghanistan's "national instruments" the Rubab and Tabla. Student will also play rhythmic and melodic patterns while improvising in the Yeman mode. Students become acquainted with the geography of Central Asia and the political Climate of Central Asia, and gain an understanding of censorship of music.

In this resource, students learn to review primary sources about African Americans in aviation during the 1940s. They use their primary source study to answer two research questions: What obstacles to full participation in aviation did African Americans face? What strategies did they use to overcome these obstacles?

This unit affords teachers with opportunities to lead children in active singing games and
dances from Quebec, Canada. These lessons will offer young singers and players an
opportunity to listen to, discuss, sing, play games, and create.

Students can learn about how Native Americans have been represented on stamps over the history of the United States. This is a resource from the Smithsonian Postal Museum and it addresses the culture of the United States.

This site providedes a brief synopsis of each of the forty-four presidents of the United States, from President George Washington to President Barack H. Obama. By clicking on their photograph at the top of the page, students will access their biography. In addition, their major accomplishments are described and various objects related to them are depicted.

Students learn about methane hydrate ice worms and hydrate shrimp, including how they obtain their food and interact with other species in deep sea ecosystems. Students will work in collaborative groups to research these organisms to develop hypotheses about the relationship between methane hydrates, ice worms, and hydrate shrimp and present their hypotheses to the class. In an extension activity, students will construct models of methane hydrate molecules.

In this resource, students can learn about the ways which the United States provided naval assistance during the two World Wars. This resource is connected with the Smithsonian Museums.

This online interactive exhibition by the Smithsonian's Air and Space Museum examines the story of America's effort to master the challenges of an unprecedented journey across thousands of miles of space is told in this online exhibition: Apollo to the Moon. The story is told through primary and secondary sources in the context of the space race between the United States and the Soviet Union.

In this lesson, students interpret graphs of global temperature records and Arctic temperature records for the past 100 years to determine differences in the rates of change between the two records.

This series of activities focuses on the world's oceans and their integral role in weather and climate. In step 1, students will identify the basic circulation patterns of the oceans and evaluate the relationship between ocean currents and trade routes of the past. In step 2, students will analyze climatic data from coastal and inland regions and conduct and experiment on the differing heat capacities of water and air. In step 3, students will locate major port cities of the world and identify ocean currents as potential travel routes. In step 4, students will explore El Nino by analyzing satellite-based data and evaluating weather reports for evidence of its occurrence.

In this lesson, students use Schoenbein paper to test for the presence of ozone in the air through a reaction between ozone and potassium iodide that produces a purple color.

In this lesson, students will learn how scientists measure small particles called aerosols in Earth's atmosphere and make their own measurements of atmospheric aerosols.

In this lesson, students create a greenhouse gas, carbon dioxide, through a simple chemical reaction, measure the effect of the gas on air temperature, and relate their findings to the greenhouse effect in our atmosphere.

In this lesson, students conduct an experiment to help students understand that ultraviolet radiation is present in natural outdoor light and that the intensity of the light varies with season and time of day.

With this interactive resource, students can explore what would happen if the amounts of oxygen, carbon dioxide, and ozone were increased or decreased on Earth.

Students will be introduced to the concept of beats in groups of two and three. Balloons, instruments, and dancing will be used to explore this concept using Polka and Waltz.
