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.

In this activity, students will experience echolocation themselves. They actually try echolocation by wearing blindfolds while another student makes snapping noises in front of, behind, or to the side of them.

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?

CLASSROOM FILMS

History.com has short videos on the Vietnam War (“Vietnam” and “A Soldier's Story”).

In this lesson, students will continue their analytical essays with a focus on the writing process. They will use the writing group protocol to bring structure to their peer editing groups.

Students are introduced to the sound environment as an important aspect of a room or building. Several examples of acoustical engineering design for varied environments are presented. Students learn the connections between the science of sound waves and engineering design for sound environments.
