Life Science worksheets
Cells, ecosystems, the human body, plants, and animals.
Life Science worksheets help K-8 students investigate the patterns and processes of living things — from a single seed becoming a sunflower to an entire ecosystem moving energy from the sun through plants and animals. Topics are built on the Next Generation Science Standards Life Science (LS) strand and the OpenStax K12 / CK-12 concept libraries.
Every Life Science topic on this page comes with eight printable worksheet formats — vocabulary matching, fill-in-the-blank, short answer, diagram labeling, a nonfiction reading passage, sort-and-classify cards, an investigation lab, and a 10-question quick quiz. Choose the format that fits your lesson today.
