About this worksheet

Environment and traits helps third graders connect observations with scientific explanations instead of memorizing isolated facts. Students may say every difference is inherited, or forget that a fair test changes only one condition. This worksheet uses short evidence-based situations so students must read the setup, identify the pattern, and choose the answer that fits the science idea named in the title. Students find the condition that caused a difference, read plant and animal growth graphs, and plan fair tests that change one thing.

Support versions use familiar examples and direct wording. Standard and challenge versions add closer distractors and require more comparison. Encourage your child to point to the evidence in the prompt before choosing an answer. If the answer does not explain the observation or solve the stated problem, it is probably a distractor. That habit builds careful science reasoning and prepares students for longer investigations.

What your child will learn

  • Find the condition that caused a difference
  • Read growth data from graphs
  • Plan a fair test
  • Tell inherited traits from environment effects

NGSS standard: 3-LS3-2

Worked example

Two bean plants from the same kind of seed get the same water, but one sits in sun and one in shade. The sunny plant grows taller, so sunlight affected its height.

Common mistake

Changing two conditions at once and then naming one as the cause.

Helpful hint

Look for the one condition that was different.
