Students construct three-dimensional models of water catchment basins using everyday objects to form hills, mountains, valleys and water sources. They experiment to see where rain travels and collects, and survey water pathways to see how they can be altered by natural and human activities. Students discuss how engineers design structures that impact water collection, as well as systems that clean and distribute water.

This interactive activity helps learners visualize the role of electrons in the formation of ionic and covalent chemical bonds. Students explore different types of chemical bonds by first viewing a single hydrogen atom in an electric field model. Next, students use sliders to change the electronegativity between two atoms -- a model to help them understand why some atoms are attracted. Finally, students experiment in making their own models: non-polar covalent, polar covalent, and ionic bonds.

This 90-minute activity features six interactive molecular models to explore the relationships among voltage, current, and resistance. Students start at the atomic level to explore how voltage and resistance affect the flow of electrons. Next, they use a model to investigate how temperature can affect conductivity and resistivity. Finally, they explore how electricity can be converted to other forms of energy. The activity was developed for introductory physics courses, but the first half could be appropriate for physical science and Physics First. The formula for Ohm's Law is introduced, but calculations are not required. This item is part of the Concord Consortium, a nonprofit research and development organization dedicated to transforming education through technology. The Concord Consortium develops deeply digital learning innovations for science, mathematics, and engineering.

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.

In this scenario-based activity, students design ways to either clean a water source or find a new water source, depending on given hypothetical family scenarios. They act as engineers to draw and write about what they could do to provide water to a community facing a water crisis. They also learn the basic steps of the engineering design process.
