This lab demonstrates Hooke's Law with the use of springs and masses. Students attempt to determine the proportionality constant, or k-value, for a spring. They do this by calculating the change in length of the spring as different masses are added to it. The concept of a spring's elastic limit is also introduced, and the students test to makes sure the spring's elastic limit has not been reached during their lab tests. After compiling their data, they attempt to find an average value of the spring's k-value by measuring the slopes between each of their data points. Then they apply what they've learned about springs to how engineers might use that knowledge in the design of a toy that enables kids to jump 2-3 feet in the air.

The Springfield Studio is a practicum design course that focuses on the economic, programmatic and social renewal of an urban community in Springfield, Massachusetts by combining classroom work with an applied class project. The course content covers the areas of neighborhood economic development and the related analysis and planning tools used to understand and assess urban conditions from an economic and community development perspective. Urban design issues are investigated in the context of social and economic challenges within the community.

Buongiorno! Welcome to Spunti: Italiano elementare 2 – a new, unique program, authored by the Italian faculty of Muhlenberg College, that takes the place of a traditional language textbook. Spunti is a fully designed course that a college instructor of Italian can use and adapt.

Welcome to Spunti: italiano intermedio – a unique program, authored by the Italian faculty of Muhlenberg College, that takes the place of a traditional language textbook. Spunti is a fully designed course that a college instructor of Italian can use and adapt.

This is a rectangle subdivision task; ideally instead of counting each square. students should break the letters into rectangles, multiply to find the areas, and add up the areas. However, students should not be discouraged from using individual counting to start if they are stuck. Often students will get tired of counting and devise the shortcut method themselves.

This short video and interactive assessment activity is designed to teach third graders an overview of area and perimeter.

This short video and interactive assessment activity is designed to give fifth graders an overview of squares and rectangles.

Squeak is a modern open-source development environment for the classic Smalltalk-80 programming language. Despite being the first purely object-oriented language and environment, Smalltalk is in many ways still far ahead of its successors in promoting a vision of an environment where everything is an object, and anything can change at run-time.

Through hands-on group projects, students learn about the force of compression and how it acts on structural components. Using everyday materials, such as paper, toothpicks and tape, they construct structures designed to (hopefully) support the weight of a cinder block for 30 seconds.

Students design and build structures to support the weight of books for 15 seconds.

Students analyze and begin to design a pyramid. Working in engineering teams, they perform calculations to determine the area of the pyramid base, stone block volumes, and the number of blocks required for their pyramid base. They make a scaled drawing of the pyramid using graph paper.

This task uses language, "half of the stamps," that students in Grade 5 will come to associate with multiplication by the fraction 12. In Grade 3, many students will understand half of 120 to mean the number obtained by dividing 120 by 2. For students who are unfamiliar with this language the task provides a preparation for the later understanding that a fraction of a quantity is that fraction times the quantity.

This art history video discussion examines the "Standard of Ur", c. 2600-2400 B.C.E. (British Museum).

From audience analysis to giving a presentation, Stand up, Speak out: The Practice and Ethics of Public Speaking will guide students through the speech making process. The authors focus on the process of speech making because they have created this book to be a user-friendly guide to creating, researching, and presenting public speeches. While both classic and current academic research in public speaking guide this book, the authors believe that a new textbook in public speaking should first, and foremost, be a practical book that helps students prepare and deliver a variety of different types of speeches — and that is the primary goal of this book.With practicality in mind, the authors developed, Stand up, Speak out: The Practice and Ethics of Public Speaking, as a streamlined public speaking textbook. Many public speaking textbooks today contain over twenty different chapters, which is often impossible to cover in a ten-week quarter or a sixteen-week semester; this textbook is eighteen unique chapters. The fifteen chapters are divided into four clear units of information: introduction to public speaking, speech preparation, speech creation, and speech presentation.

What is a star and what shape is it? Students explore both artistic and scientific representations of stars, learn that stars are like the sun but much further away and make their own star hat.

Have you ever wondered what happens to the different stars in the night sky as they get older? The Star in a Box application lets you explore the life cycle of stars. It animates stars with different starting masses as they change during their lives. Some stars live fast-paced, dramatic lives; others change very little for billions of years. The app visualises the changes in mass, size, brightness and temperature for all these different stages.

To get a better understanding of complex networks, students create their own, real social network example by interacting with their peers in the classroom and documenting the interactions. They represent the interaction data as a graph, calculate two mathematical quantities associated with the graph—the degree of each node and the degree distribution of the graph—and analyze how these quantities can be used to infer properties of the social network at hand.
