Students learn about various natural hazards and specific methods engineers use to prevent these hazards from becoming natural disasters. They study a hypothetical map of an area covered with natural hazards and decide where to place natural disaster prevention devices by applying their critical thinking skills and an understanding of the causes of natural disasters.

There are many misconceptions about the chemistry concept, “Conservation of Mass”. Thus, the aim of this video lesson is to teach students about the chemical concept of Conservation of Mass through several chemistry experiments. The students will carry out experiments while assisting a fortune teller named Pak Belalang to gain victory for his kingdom. In an effort to help Pak Belalang, students should be able to answer all the questions related to the Conservation of Mass that are posed by an evil witch. In this video, materials such as a box of matches, a closed and open container, a box of panadol soluble tablets (Alka-Seltzer), and weighing scales are needed. At the end of the lesson, students will be able to see that mass is “conserved”. The lesson will take up to 60 minutes to complete.

Student teams practice water quality analysis through turbidity measurement and coliform bacteria counts. They use information about water treatment processes to design prototype small-scale water treatment systems and test the influent (incoming) and effluent (outgoing) water to assess how well their prototypes produce safe water to prevent water-borne illnesses.

Students develop an understanding of the concepts of "push" and "pull" as they "save" stuffed animals from danger using LEGO MINDSTORMS(TM) NXT robots. After learning more about the concepts through a robot demonstration, students explore the concepts themselves in the context of saving stuffed animala from the table edges. They choose to either push or pull the animal to safety, depending on the orientation of the robot and toy. They see the consequences of their choices, learning the importance of understanding these force concepts and the differences between them.

In this challenging instructional task students relate addition and subtraction problems to money and to situations and goals related to saving money.

Students use their knowledge about how healthy heart valves function to design, construct and implant prototype replacement mitral valves for hypothetical patients' hearts. Building on what they learned in the associated lesson about artificial heart valves, combined with the testing and scoring of their prototype heart valve designs in this activity, students discover the pros and cons of different types of artificial heart valves based on materials, surgery requirements, and lifespan.

This brief activity leads students through analysis of an archaeologist's sketch of the grave of an African buried in colonial New York.

Students build scale models of objects of their choice. In class they measure the original object and pick a scale, deciding either to scale it up or scale it down. Then they create the models at home. Students give two presentations along the way, one after their calculations are done, and another after the models are completed. They learn how engineers use scale models in their designs of structures, products and systems. Two student worksheets as well as rubrics for project and presentation expectations and grading are provided.

Students gain an understanding of the layers of the Earth by designing and building clay models.

Students learn how different characteristics of shapes—side lengths, perimeter and area—change when the shapes are scaled, either enlarged or reduced. Student pairs conduct a “scaling investigation” to measure and calculate shape dimensions (rectangle, quarter circle, triangle; lengths, perimeters, areas) from a bedroom floorplan provided at three scales. They analyze their data to notice the mathematical relationships that hold true during the scaling process. They see how this can be useful in real-world situations like when engineers design wearable or implantable biosensors. This prepares students for the associated activity in which they use this knowledge to help them reduce or enlarge their drawings as part of the process of designing their own wearables products. Pre/post-activity quizzes, a worksheet and wrap-up concepts handout are provided.

Students learn how to determine map distances and areas using the map scale. They get a feel for how much an area represents on the map in relation to the size they are suggesting for their underground caverns to shelter the Alabraska population.

This collection uses primary sources to explore The Scarlet Letter by Nathaniel Hawthorne. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

What are the circuits, mechanisms and representations that permit the recognition of a visual scene from just one glance? In this one-day seminar on Scene Understanding, speakers from a variety of disciplines -- neurophysiology, cognitive neuroscience, visual cognition, computational neuroscience and computer vision -- will address a range of topics related to scene recognition, including natural image categorization, contextual effects on object recognition, and the role of attention in scene understanding and visual art. The goal is to encourage exchanges between researchers of all fields of brain sciences in the burgeoning field of scene understanding.

This art history video discussion looks at Christian Schad's "Self-Portrait", 1927, oil on wood, 29 x 24-3/8 inches, 76 x 62 cm (Tate Modern, London).

This art history video discussion looks at Egon Schiele's "Hermits" 1912, oil on canvas (Leopold Museum, Vienna).

This art history video discussion looks at Egon Schiele's "Seated Male Nude (Self-Portrait)", 1910, oil and gouache on canvas (Leopold Museum, Vienna).

Dostoyevsky's Crime and Punishment, is a CCSS exemplar for grades 11 "“ CCR taught at the upper high school level and in AP English. This three lesson unit looks at a variety of schisms and divisions in the novel. It provides a close reading of the novel by considering Dostoevsky's view of human nature, through his characters; the theoretical division Man v Superman; the societal setting in the novel.

This word problem may be used for instructional or assessment purposes, depending on where students are in their understanding of addition and how the teacher supports them.

A survey of developments in Western musical style from 1810-1910. Thirty composers discussed including the Romantics Schubert, Berlioz, Chopin, Schumann, and Liszt; and the post-Romantics Wagner, Verdi, Brahms, Strauss, Farwell, and Mahler. Required reading, score-reading, and listening assignments.
