Similarities Between Parents and Offspring

Turn inherited traits into a reasoning task with this scaffolded worksheet for grades 3-5. Students analyze a side-by-side plant family model in which both parents share the same flower color but differ in stem height, so the pattern of inheritance and variation reads straight off the diagram.

The sheet builds toward real scientific thinking. Students first answer guided questions about which traits are shared and which vary, then complete a full claim-evidence-reasoning task. They choose the stronger claim, select the two best pieces of evidence from four options (two are deliberate distractors), and write their reasoning using a sentence starter.

This is analysis, not recall: students must use the model as data to explain why offspring resemble their parents yet are never identical. Includes seven items and a complete answer key with sample responses. Aligned to NGSS 3-LS3-1 and pitched for upper-elementary learners. Just print and teach.
