Compare observations of DNA and describe the pattern you notice — free printable Middle School Science worksheet

This Grades 6–8 Life Science worksheet asks students to compare observations of DNA structures — including double-helix models and base-pair sequences — and describe the patterns they notice, connecting structure to function in genetics. Teachers can use it as a model-analysis activity within a genetics and biotechnology unit or as a formative check after instruction on DNA replication and gene expression. It supports standards that require students to explain how DNA carries genetic information and how that information is expressed.

Learning objectives

  • Compare observations of DNA structures to identify patterns in their composition
  • Describe the base-pairing rules and how they relate to DNA structure
  • Connect observed structural patterns in DNA to their role in genetic inheritance
