Science Essentials Middle School Level gives classroom teachers and science specialists a dynamic and progressive way to meet curriculum standards and competencies. Science Essentials are also available from Jossey--Bass publishers at the Elementary and High School Levels. You'll find the lessons and activities at each level actively engage students in learning about the natural and technological world in which we live by encouraging them to use their senses and intuitive abilities on the road to discovery. They were developed and tested by professional science teachers who sought to give students enjoyable learning experiences while preparing them for district and statewide proficiency exams. For easy use, the lesson and activities at the Middle School Level are printed on a big 8 x 11 lay--flat format that folds flat for photocopying of over 165 student activity sheets, and are organized into four sections: * PHYSICAL SCIENCE: MOTION AND FORCES (22 Lessons) * CHEMISTRY (34 Lessons) * ASTRONOMY (16 Lessons) * BIOLOGY (12 Lessons)
