Physical and Chemical Change

Grade 5 - Science - On Level

Worksheet 1

  1. Classify this change: paper is cut into small squares.

  2. Which evidence supports the claim that "baking soda and vinegar fizz" is a chemical change?

  3. Which observation is about new substances in this event: baking soda and vinegar fizz?

  4. Which model step is most important for deciding whether baking soda and vinegar fizz is physical or chemical?

    Sequence cards show before, change, and after observations.3 cards placed left to right, each describing one event and numbered in order.1observe before2change happens3observe after

  5. Why is "the nail is only bent" not the best evidence for "a steel nail rusts"?

  6. Classify this change: wood burns in a campfire.

  7. Which evidence supports the claim that "wood burns in a campfire" is a chemical change?

  8. Which observation is about new substances in this event: wood burns in a campfire?

  9. Which model step is most important for deciding whether milk turns sour is physical or chemical?

About this worksheet

Physical and chemical change questions ask students to decide whether matter only changes form or whether new substances form asks fifth graders to connect a model, data table, or observation with a scientific explanation. Students may label any dramatic event as chemical or any quiet event as physical, instead of looking for evidence such as gas, ash, rust, odor, or recoverable material. This worksheet keeps each question tied to the named science idea, so students cannot answer by eliminating vocabulary from a different unit. Students classify changes, identify evidence for new substances, compare physical changes with reactions, and reject observations that do not support the claim. Support versions use familiar examples and direct observations. Standard and challenge versions add closer distractors, multi-step evidence, and model-based reasoning. Ask your child to point to the measurement, diagram, or cause-and-effect clue before choosing. If an answer sounds scientific but does not explain the evidence in the prompt, it is probably a distractor.

What your child will learn

  • Classify changes
  • Find new-substance evidence
  • Compare observations
  • Use matter evidence

Worked example

Rusting is a chemical change because a new reddish-brown substance forms on the metal.

Common mistake

Calling a change chemical just because the object looks different.

Helpful hint

Ask whether a new substance with new properties formed.
