This curriculum unit presents an overview of privacy as a concept intrinsic to the functioning of a democratic society. The unit requires students to examine the concept of privacy, some differences among individuals and cultures in relation to it, its benefits and costs, and its proper scope and limits. The curriculum is organized around topical questions that provide a systematic approach to the analysis and evaluation of privacy. This edition of the curriculum, for students in grades 2 and 3, contains four units, each of which concerns a topical question. Unit 1 asks, "Que es la intimidad o privacidad personal?" (What is privacy?). Unit 2 asks, "Como se explicaran las diferencias de conducta para conseguir la intimidad?" (What factors might explain differences in privacy behavior?). Unit 3 asks, "Cuales son los beneficios y los costos que causa la intimidad?" (What might be some benefits and costs of privacy?). Unit 4 asks, "Que abarca y hasta donde se limita la intimidad?" Each lesson in the teacher's guide features an overview, objectives, student materials, and learning procedures. This document is the English-Spanish Bilingual Edition of the curriculum, which has been created to provide Spanish-speaking students of limited English proficiency with an opportunity to participate in the instructional activities described.
