About this worksheet

Plant life cycles show how plants grow, flower, make seeds, and begin the pattern again helps third graders connect observations with scientific explanations instead of memorizing isolated facts. Students may remember one stage but place it in the wrong order, or they may miss that pollination and seeds are what let the cycle continue. 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 order stages, find missing stages in a cycle diagram, connect flowers and pollen to seeds, and compare how seeds, cones and spores start new plants.

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

Worked example

A bean plant grows from a seed to a sprout, then an adult plant with flowers. Bees carry pollen, the flowers make pods with seeds, and each seed can start the cycle again.
