Students use ultrasonic sensors and LEGO© MINDSTORMS© NXT robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold values, and again after making adjustments to optimize its effectiveness. Like engineers, they gather and graph data to analyze a given design (from the tutorial) and make modifications to the sensor placement and/or threshold values in order to improve the robot's performance (iterative design). Students see how problem solving with biomimicry design is directly related to understanding and making observations of nature.

Students' understanding of how robotic ultrasonic sensors work is reinforced in a design challenge involving LEGO MINDSTORMS(TM) NXT robots and ultrasonic sensors. Student groups program their robots to move freely without bumping into obstacles (toy LEGO people). They practice and learn programming skills and logic design in parallel. They see how robots take input from ultrasonic sensors and use it to make decisions to move, resulting in behavior similar to the human sense of sight but through the use of sound sensors, more like echolocation. Students design-test-redesign-retest to achieve successful programs. A PowerPoint® presentation and pre/post quizzes are provided.

The 11th grade learning experience consists of 7 mostly month-long units aligned to the Common Core State Standards, with available course material for teachers and students easily accessible online. Over the course of the year there is a steady progression in text complexity levels, sophistication of writing tasks, speaking and listening activities, and increased opportunities for independent and collaborative work. Rubrics and student models accompany many writing assignments.

Throughout the 11th grade year, in addition to the Common Read texts that the whole class reads together, students each select an Independent Reading book and engage with peers in group Book Talks. Students move from learning the class rituals and routines and genre features of argument writing in Unit 11.1 to learning about narrative and informational genres in Unit 11.2: The American Short Story. Teacher resources provide additional materials to support each unit.

In this unit, students will explore great works of American literature and consider how writers reflect the time period in which they write. They will write two literary analysis papers and also work in groups to research and develop anthologies of excellent American stories.

ACCOMPLISHMENTS

Students read and analyze stories from several 19th-, 20th-, and 21st-century American authors. After researching a time period, they select stories from that period to create an anthology. The readings enhance their understanding of the short story, increase their exposure to well-known American authors, and allow them to examine the influence of social, cultural, and political context.
Students examine elements of short stories and have an opportunity for close reading of several American short stories. During these close readings, they examine the ways that short story writers attempt to explore the greater truths of the American experience through their literature.

GUIDING QUESTIONS

These questions are a guide to stimulate thinking, discussion, and writing on the themes and ideas in the unit. For complete and thoughtful answers and for meaningful discussions, students must use evidence based on careful reading of the texts.

If you were to write a short story about this decade, what issues might you focus on?
What defines a short story? Just length?
To what extent do these stories reflect the era or decade in which they were written?
To what extent are the themes they address universal?

Students model and design the sound environment for a room. They analyze the sound performance of different materials that represent wallpaper, thick curtains, and sound-absorbing panels. Then, referring to the results of their analysis, they design another room based on certain specifications, and test their designs.

Traces the evolution of this Maryland site from a chapter of the Chautaqua movement, to an amusement park, to a national park. This spectacular Maryland location, so lovingly described by Edward and Edwin Baltzley, its first developers, has served the people of Washington, D.C., as a center for education and recreation for more than 100 years. It was first developed as a chapter of the widespread Chautauqua movement–a Protestant ecumenical effort to democratize learning and spread culture from the well-to-do to the masses. Early in the 20th century the area was redeveloped as a trolley park, and now the site is preserved as a national park. The trends that impacted the development and redevelopment of the Glen Echo Park site are not unusual; the fact that they impacted the same area of space is. This unique survivor, a traditional gathering place for the people of Washington, D.C., provides students with the opportunity to study the evolution of the American concepts of education, recreation, and social interaction in the late 19th and 20th centuries. Lesson plan included.

Students learn about how ultrasonic sensors work, reinforcing the connection between this sensor and how humans, bats and dolphins estimate distance. They learn the echolocation process sound waves transmitted, bounced back and received, with the time difference used to calculate the distance of objects. Two mini-activities, which use LEGO MINDSTORMS(TM) NXT robots and ultrasonic sensors, give students a chance to experiment with ultrasonic sensors in preparation for the associated activity. A PowerPoint® presentation explains stimulus-to-response pathways, sensor fundamentals, and details about the LEGO ultrasonic sensor. Pre/post quizzes are provided. This lesson and its associated activity enable students to gain a deeper understanding of how robots can take sensor input and use it to make decisions via programming.

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. Understanding the properties of sound and how sound waves travel helps engineers determine the best room shape and construction materials when designing sound recording studios, classrooms, libraries, concert halls and theatres.
