About this worksheet

Children often decide that anything that moves is alive, which makes a rolling ball or a moving toy especially confusing. Scientists use evidence instead: living things grow, need resources, and make more of their own kind. A thing does not need to show every trait at the moment we observe it. A seed may look still, yet it can grow under the right conditions. This worksheet asks first graders to classify familiar examples and, more importantly, choose the observation that supports each decision. Support questions use obvious plants, animals, and classroom objects. Challenge questions include seeds, fallen leaves, and machines that move. Listen for explanations based only on motion, shape, or where something is found. Ask your child to finish the sentence, “I know because…” so the category is tied to evidence rather than a guess.

What your child will learn

  • Tell living things from nonliving objects
  • Use growth and needs as evidence
  • Explain why motion alone does not prove life
  • Classify less obvious examples such as seeds

Worked example

A puppy is living because it grows and needs food and water. A toy puppy is nonliving even if a battery makes it move.

Common mistake

Calling every object that moves living, even when a person, wind, or battery causes the motion.

Helpful hint

Ask whether it grows and needs food or water.

Plant Parts and Needs
