Page | 2 Curriculum – 7th Grade Science Triton Central Middle School 7th grade science Narrative Description Seventh grade science consists of a mix of earth science, physical science, and life science. Many of the concepts overlap and build on each other throughout the year allowing repetition to better enable students to retain the information. Page | 3 Curriculum – 7th Grade Science Course Concepts and Generalizations The Nature of Science and Technology Students gain scientific knowledge by observing the natural and constructed world, performing and evaluating investigations, and communicating their findings. These principles should guide student work and be integrated into the curriculum along with the content standards on a daily basis. Physical Science Explain that energy cannot be created or destroyed but instead can only be changed from one form into another or transferred from place to place. Describe and investigate how forces between objects can act at a distance or by means of direct contact between objects. Earth and Space Systems Describe how earth processes have shaped the topography of the earth and have made it possible to measure geological time. Life Science Understand the cellular structure of single-celled and multicellular organisms. The Design Process As citizens of the constructed world, students will participate in the design process. Students will learn to use materials and tools safely and employ the basic principles of the engineering design process in order to find solutions to problems.
