What Makes Something Alive? Living, Once-Living, and Nonliving Reading Comprehension Passage and Questions

This reading explores how scientists use evidence to classify objects as living, once-living, biologically produced but never independently living, or nonliving. Students learn that appearance, movement, growth, or biological origin alone cannot determine whether something is alive. Instead, scientists examine an object’s present organization and activity, its ability to perform life processes, and its biological or material history.

Students apply these ideas to challenging examples such as dormant seeds, dead leaves, wooden desks, eggshells, fossils, viruses, flames, and quartz crystals. They examine the differences between dormancy and death, consider why something made by an organism was not necessarily alive itself, and evaluate why viruses remain difficult to classify. The reading emphasizes using multiple lines of evidence to make and defend scientific classifications.

This resource covers the following topics:

✅ Grade 8 and Up Reading on Classifying Living and Nonliving Things: Explains how scientists use evidence to determine an object’s current state and biological history.

✅ No-Prep, Editable Resource: Easy to assign as print or digital scientific literacy practice.

✅ Four-Category Classification System: Students distinguish among living, once-living, biologically produced but never independently living, and nonliving objects.

✅ Challenging Real-World Examples: Students classify dormant seeds, dead leaves, wood, eggshells, fossils, viruses, flames, and crystals.

✅ Includes Reading Comprehension and Extension Questions: Comes with 10 comprehension questions, 5 extension questions, and complete answer keys.
