This art history video discussion looks at the Mosaics of Santa Prassede, Rome, early 9th century Mosaics from the early 9th century, under Pope Paschal. The church is dedicated to Saint Praxedes and her sister Saint Pudentiana, daughters of Saint Pudens. The sisters were martyred because they provided Christian burials for martyrs, against Roman law.

This task involves a fairly straightforward decaying exponential. Filling out the table and developing the general formula is complicated only by the need to work with a fraction that requires decisions about rounding and precision.

This task describes two linear functions using two different representations. To draw conclusions about the quantities, students have to find a common way of describing them. We have presented three solutions (1) Finding equations for both functions. (2) Using tables of values. (3) Using graphs.

Students explore the properties of composites using inexpensive materials and processing techniques. They create beams using Laffy Taffy and water, and a choice of various reinforcements (pasta, rice, candies) and fabricating temperatures. Student groups compete for the highest strength beam. They measure flexure strength with three-point bend tests and calculations. Results are compared and discussed to learn how different materials and reinforcement shapes affect material properties and performance.

In 2016, a billionaire businessman and the first woman nominated by a major party ran against each other for president of the United States. In very different ways, both candidates approached the presidency as outsiders, reaching beyond the traditional boundaries of US presidential politics. As outsiders, the 2016 candidates are noteworthy, but not unique; indeed, the 2016 race resonates with the legacies of outsiders who have come before. This exhibition explores the rich history of select individuals, parties, events, and movements that have influenced US presidential elections from the outside—outside Washington politics, outside the two-party system, and outside the traditional conception of who can be an American president.

Using gumdrops and toothpicks, students conduct a large-group, interactive ozone depletion model. Students explore the dynamic and competing upper atmospheric roles of the protective ozone layer, the sun's UV radiation and harmful human-made CFCs (chlorofluorocarbons).
The primary audience for this book starts with students in Journalism 302: …
The primary audience for this book starts with students in Journalism 302: Infomania, a course we teach at the University of Kansas. When they take this class, these students usually are in their second or third semesters in the William Allen White School of Journalism and Mass Communications. They have varied career aspirations. A few of them want to be “traditional” journalists, writing for online news sites, magazines, or newspapers. Some of them want to be broadcast journalists. Many of them want to work in strategic communications, which encompasses public relations, advertising, marketing, and related fields.

Online tools are empowering for kids, and they also come with big responsibilities. But do kids always know what to do when they encounter cyberbullying? Show your students appropriate ways to take action and resolve conflicts, from being upstanders to helping others in need.

In this activity, students learn about their heart rate and different ways it can be measured. Students construct a simple measurement device using clay and a toothpick, and then use this device to measure their heart rate under different circumstances (i.e., sitting, standing and jumping). Students make predictions and record data on a worksheet.
Lighting is responsible for nearly one-third of the electricity use in buildings. …
Lighting is responsible for nearly one-third of the electricity use in buildings. One of the best ways to conserve energy is to make sure the lights are turned off when no one is in a room. This process can be automated using motion sensors. In this activity, students explore material properties as they relate to motion detection, and use that knowledge to make design judgments about what types of motion detectors to use in specific applications.

In this 1-2 week engineering design lesson, students will design and build water filters out of natural materials to simulate a filter system (bioswales) that cleans storm-water runoff before it soaks into the ground or enters a city’s storm-drain system. Their ultimate goal is to determine the combination and sequence of materials that best clean polluted water. Using materials easily found in pet stores and garden centers, students use the scientific method, students design to test and retest their designs and record, display and analyze their results.

The University of North Georgia Press and Affordable Learning Georgia bring you Becoming America: An Exploration of American Literature from Precolonial to Post-Revolution. Featuring sixty-nine authors and full texts of their works, the selections in this open anthology represent the diverse voices in early American literature. This completely-open anthology will connect students to the conversation of literature that is embedded in American history and has helped shaped its culture.

The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with Beer's Law. "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer! The simulation is also paired with a teachers' guide and related resources from PhET. The simulation is also available in multiple languages.

The study of biomimicry and sustainable design promises great benefits in design applications, offering cost-effective, resourceful, non-polluting avenues for new enterprise. An important final caveat for students to understand is that once copied, species are not expendable. Biomimicry is intended to help people by identifying natural functions from which to pattern human-driven services. Biomimicry was never intended to replace species. Ecosystems remain in critical need of ongoing protection and biodiversity must be preserved for the overall health of the planet. This activity addresses the negative ramifications of species decline. For example, pollinators such as bees are a vital work force in agriculture. They perform an irreplaceable task in ensuring the harvest of most fruit and vegetable crops. In the face of the unexplained colony collapse disorder, we are only now beginning to understand how invaluable these insects are in keeping food costs down and even making the existence of these foods possible for humans.
