Grade 1 - Science - Building Confidence
Worksheet 1
1A scientist observes a bird. How should it be sorted?
2Which observation is the best evidence that a bird is living?
3Which test would help decide whether the bird is living?
4The bird can move. What else must be checked before calling it living?
5Complete the science claim: A rock is nonliving because _____.
6Which science group belongs on the label for a bird?
7A class calls a pencil nonliving. Which fact supports their claim?
8What long-term observation would reveal whether a sunflower has a life process?
9Movement alone does not classify the bird. Which trait is stronger evidence?

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.
