Unified Science 7

Course Description

This course consists of three units: Diversity of Life, Earth History, and Force and Motion. In the first unit, students observe and maintain protists, plants, and animals in the classroom and study their characteristic features. In the second, students investigate rocks and fossils to discover clues that reveal Earth’s history. They explore sedimentary rocks and fossils from the Grand Canyon, consider the processes that created them, and compare evidence discovered in the rocks to present-day geologic processes and contemporary life forms. In the third unit, students investigate linear motion, including position, and several aspects of change of position—distance, speed, and acceleration. They investigate fundamental forces (gravity and electromagnetism) in familiar environments, such as pushes, pulls, impacts, and falls. An object in motion has momentum, and momentum is conserved. Students acquire the most important understanding about the interplay between force and motion: Force= mass X acceleration.
