River Dell Regional School District 4 Seventh Grade Science Curriculum Approved September 26, 2016
Rationale The science 7 course helps students develop understanding of key concepts in the life sciences. Students start by investigating cells. Students should know that all organisms are made of cells and that cells can specialize for particular functions within organisms. Cells are organized into interacting subsystems that allow organisms to stay alive. Students then study the processes that transfer energy within organisms and between organisms and their environment. Students next address how organisms use energy to grow, develop and reproduce. With an understanding of how traits are passed via genetic material, students are ready to learn about how changes in DNA lead to changes in organisms over longer periods of time. The course is also designed to help students understand the practices used by scientists and engineers. Students model scientific phenomena, carry out investigations, analyze data, use mathematical representations, construct arguments supported by empirical evidence, evaluate design solutions, and synthesize information from multiple sources. The major topics are 1) structure, function, and information processing, 2) ecosystems: interactions, energy, and dynamics, 3) growth, development, and reproduction of organisms, and 4) natural selection and adaptations. The cross cutting concepts of cause and effect, patterns, energy and matter, stability and change, scale, proportion, and quantity, systems and system models, and structure and function are addressed throughout the year to help make additional connections to the disciplines of earth and physical science. The curriculum also addresses the nature of science and connections to engineering and technology. Ultimately, all students regardless of whether they pursue science related fields should be able to make informed decisions about science issues that affect society.
