Students are introduced to superhydrophobic surfaces and the "lotus effect." Water spilled on a superhydrophobic surface does not wet the surface, but simply rolls off. Additionally, as water moves across the superhydrophobic surface, it picks up and carries away any foreign material, such as dust or dirt. Students learn how plants create and use superhydrophobic surfaces in nature and how engineers have created human-made products that mimic the properties of these natural surfaces. They also learn about the tendency of all superhydrophobic surfaces to develop water droplets that do not roll off the surface but become "pinned" under certain conditions, such as water droplets formed from condensation. They see how the introduction of mechanical energy can "unpin" these water droplets and restore the desirable properties of the superhydrophobic surface.

This course explores the relationship between music and the supernatural, focusing on the social history and context of supernatural beliefs as reflected in key literary and musical works from 1600 to the present. It provides an understanding of the place of ambiguity and the role of interpretation in culture, science and art. Great works of art by Shakespeare, Verdi, Goethe (in translation), Gounod, Henry James and Benjamin Britten are explored, as well as readings from the most recent scholarship on magic and the supernatural.

At this stage of the "Lost in the Amazon" (hypothetical) adventure, students determine what supplies they will take with them to survive their trip through the Amazon. They use estimation and basic math skills to determine how much they can carry and what they can use to survive in the jungle environment as they travel on to their destination.

Supply Chain Planning focuses on effective supply chain strategies for companies that operate globally, with an emphasis on how to plan and integrate supply chain components into a coordinated system. Students are exposed to concepts and models important in supply chain planning with emphasis on key tradeoffs and phenomena. The course introduces and utilizes key tactics such as risk pooling and inventory placement, integrated planning and collaboration, and information sharing. Lectures, computer exercises, and case discussions introduce various models and methods for supply chain analysis and optimization.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.

In this activity, students develop Common Core reading skills (eg. citing textual evidence, determining the central ideas, and determining meaning of words and phrases) through a study of the history of the second amendment to the U.S. Constitution and its significance today. First, students work independently, with some class discussion, to complete a close reading of the second amendment text and related primary and secondary documents. Then, students work in groups to prepare a presidential candidate for a debate in which he/she must defend a particular position, or claim, about the meaning of the second amendment and constitutionality of gun regulation.

The goal of these materials is to illustrate how Common Core aligned math tasks can be used to support math instruction and language development for ELLs at three grade spans (elementary, middle, and high school). We used or adapted tasks from two publicly accessible curriculum projects, Inside Mathematics and Mathematics Assessment Project.

This multidisciplinary resource develops topics of interest to all those who care about and for individuals with co-occurring intellectual disabilities and mental illness. Each chapter presents current evidence informed practice knowledge. Each topic is also presented with audio enabled text boxes emphasizing 'Key Points for Caregivers.' For those who are interested in background knowledge, we provided the comprehensive literature base. And, for those interested mainly in 'what to do,' we provided text box summaries for reading and listening.

The federal judiciary, which includes the Supreme Court as well as the district and circuit courts, is one of three branches of the federal government. This lesson provides an introduction to the Supreme Court.

The course offers an introduction to quantitative analysis of geomorphic processes,and examines the interaction of climate, tectonics, and surface processes in the sculpting of Earth's surface.

Surface tension accounts for many of the interesting properties we associate with water. By learning about surface tension and adhesive forces, students learn why liquid jets of water break into droplets rather than staying in a continuous stream. Through hands-on activities, students learn how the combination of adhesive forces and cohesive forces cause capillary motion. They study different effects of capillary motion and use capillary motion to measure surface tension. Students explore the phenomena of wetting and hydrophobic and hydrophilic surfaces and see how water's behavior changes when a surface is treated with different coatings. A lotus leaf is a natural example of a superhydrophobic surface, with its water-repellent, self-cleaning characteristics. Students examine the lotus effect on natural leaves and human-made superhydrophobic surfaces, and explore how the lotus leaf repels dewy water through vibration. See the Unit Overview section for details on each lesson in this unit.

Students are presented with the question: "Why does a liquid jet break up into droplets?" and introduced to its importance in inkjet printers. A discussion of cohesive forces and surface tension is included, as well as surface acting agents (surfactants) and their ability to weaken the surface tension of water. Students observe the effects of surface tension using common household materials. Finally, students return to the original question through a homework assignment that helps them relate surface tension and surface area to the creation of water droplets from a liquid jet.

Students extend their understanding of surface tension by exploring the real-world engineering problem of deciding what makes a "good" soap bubble. Student teams first measure this property, and then use this measurement to determine the best soap solution for making bubbles. They experiment with additives to their best soap and water "recipes" to increase the strength or longevity of the bubbles. In a math homework, students perform calculations that explain why soap bubbles form spheres.

In an activity that integrates science and art, students see, experience and harness the phenomenon of surface tension as they create beautiful works of art. Students conduct two experiments related to surface tension floating objects on the surface of water and creating original artwork using floating inks. They also learn historical and cultural information through an introduction to the ancient Japanese art form of suminagashi. They take the topic a step further by discussing how an understanding of surface tension can be applied to solve real-world engineering problems and create useful inventions.

Students learn about the basics of molecules and how they interact with each other. They learn about the idea of polar and non-polar molecules and how they act with other fluids and surfaces. Students acquire a conceptual understanding of surfactant molecules and how they work on a molecular level. They also learn of the importance of surfactants, such as soaps, and their use in everyday life. Through associated activities, students explore how surfactant molecules are able to bring together two substances that typically do not mix, such as oil and water. This lesson and its associated activities are easily scalable for grades 3-12.

This lesson introduces the concepts of longitudinal and transverse waves. Students see several demonstrations of waves and characterize them by transverse and longitudinal behavior. This lesson also introduces the Sunken Treasure theme of the Sound and Light unit a continuous story line throughout the lessons.

This unit focuses on teaching students about the many aspects of biomedical engineering (BME). Students come to see that BME is a broad field that relies on concepts from many engineering disciplines. They also begin to understand some of the special considerations that must be made when dealing with the human body. Activities and class discussions encourage students to think as engineers to come up with their own solutions to some of medical challenges that have been solved throughout the history of BME. Class time iincludes brainstorming and presenting ideas to the class for discussion. Specific activities include examination of the material properties and functions of surgical instruments and prosthetics, a simulation of the training experience of a surgical resident, and an investigation of the properties of fluid flow in vascular tissue.

Students act as surgical residents for the day. Working in teams, they use surgical instruments to complete tasks that are inside of a box, hidden from direct view. They are able to see inside of the box with the help of a "laparoscope" (webcam and flashlight). This engaging activity shows students one application of engineered medical instrumentation and gives them first-hand experience in seeing how form fits function. They also learn that an engineer's job does not end with a finished product because s/he must train others to use the device correctly.
