Biology lesson plan: DNA, chromosomes and inherited traits
Topic: Role of DNA and chromosomes in coding traits passed from parents to offspring (HS-LS3-1). Adjust the settings, then copy the prompt.

Planning notes for this lesson
Prerequisite skills to check: genes are made of DNA and carry information (MS-LS3-1); chromosomes and cell division basics (MS-LS3-2); cells have a nucleus that holds genetic material (MS-LS1-2).
Warm-up idea: Ask why siblings can share a family resemblance but still look different from each other, and collect student ideas before naming DNA and chromosomes.
Exit ticket idea: Students explain, in their own words, how DNA on chromosomes carries instructions for traits, and write two questions they still have about how a parent's DNA relates to an offspring's traits (staying inside the HS-LS3-1 assessment boundary).
Always check the AI's plan and answers before you teach.
