What is a frontier? What are the frontiers of the future? What frontiers are being explored today? These and other questions are presented in this series on frontiers that help make this concept come alive to all students. The books in Prufrock's Differentiated Curriculum Kits employ a differentiated, integrated curriculum based on broad themes. This all-in-one curriculum helps teachers save planning time, ensure compliance with national standards, and most importantly, pique their students' natural excitement and interest in discovery. By participating in the wide variety of activities in the Differentiated Curriculum Kit for Grade 6, students will discover the frontiers around them and gain a lifelong desire to learn. In Frontiers Book 1: Pioneers, Genetics, and Energy, students will explore forgotten pioneers in the Westward expansion, the Civil Rights Movement, and medicine. In Frontiers Book 2: Geography, Explorers, and Literature, students will follow the trail of Lewis and Clark, as well as other explorers that broke through geographic and literary frontiers. In Frontiers Book 3: Geology, Astonomy, and Environment, students will explore plate tectonics, the rock cycle, Mars, and conservation of natural resources. Each book contains detailed lesson plans, reproducible activity sheets, and assessment tools.
