NGSS Life Science

NGSS Life Science provides science and engineering practice resources and NGSS-aligned biology curriculum for middle and high school teachers. Its materials are designed to support inquiry-based instruction, hands-on learning, and scaffolded activities that encourage students to ask questions, investigate problems, develop models, and explain scientific ideas. The site offers free biology lessons, alongside a membership option that provides editable lesson files, answer keys, and test-question banks.

The curriculum spans a wide range of life science topics, including bioenergetics, cell biology, ecology, evolution, genetics, biochemistry, and organism-level biology. Teachers can find worksheets, labs, projects, and tests covering subjects such as photosynthesis, cellular respiration, cell division, food webs, natural selection, DNA, human body systems, and microorganisms. Resources for science practices include materials on the scientific method and the metric system. Membership downloads are provided in DOCX, PPTX, and XLSX formats, supporting both digital and traditional classroom use. NGSS Life Science also shares guidance on integrating science and engineering practices with NGSS and Common Core learning, helping teachers connect curriculum content with student inquiry.
