New York Science — Grade 7

Comprehensive Course Syllabus

Course Overview

Our New York Grade 7 Science course is the most demanding yet. Students meet atoms, DNA, chemical reactions, and natural selection — the explanatory frameworks that make sense of everything they have studied so far.

The life science strand covers cells and cell theory, diffusion, osmosis, and homeostasis, the organisation of living systems, nine human body systems, photosynthesis and cellular respiration as complementary processes, genetics, DNA, chromosomes, and mutation, reproduction, and natural selection.

The ecology strand covers ecosystems, food webs and trophic levels, matter cycling including the carbon cycle, symbiotic relationships, and biodiversity with human impact. The physical science strand introduces atomic structure, the periodic table, elements and compounds, and chemical reactions with conservation of matter.

Students then study energy and its conservation, heat transfer, forces and motion, Newton’s three laws, waves, sound and light, and electricity and magnetism. The year closes with Earth’s systems, weather and climate including climate change, and engineering design applied to environmental problems.

Standards Note

This syllabus is aligned broadly with the New York State P-12 Science Learning Standards (NYSSLS) for Grade 7. It is designed to explain clearly to parents and students what Grade 7 science covers.

New York State schools, districts, and charter schools may use different textbooks, curriculum programmes, laboratory resources, pacing guides, and assessment systems, and may sequence middle-school science differently across Grades 6 to 8. This syllabus does not claim that every New York school follows the same programme.

This is not the only official Grade 7 Science syllabus in New York. It is one structured pathway through the Grade 7 standards, created for this educational programme.

Scientific topics including evolution by natural selection, reproduction, and climate change are presented factually and age-appropriately as established science, consistent with the New York State Science Learning Standards.

It is important to distinguish between the New York State Science Learning Standards and the course structure created for this educational programme, which organises those standards into 32 teachable modules.
