MS-LS4-5
The standard
Gather and synthesize information about the technologies that have changed the way humans influence the inheritance of desired traits in organisms.
Next Generation Science Standards
What this standard means
Students need to collect information from reliable sources about ways people change inherited traits in plants, animals, or humans. They should compare older methods, like selective breeding, with newer tools, like genetic modification and gene therapy. They also need to explain benefits, risks, limits, and social impacts.
Mastery looks like a clear synthesis, not a copied report. Students can connect a technology to a trait outcome and support claims with evidence from sources. Common struggles are confusing learned traits with inherited traits, using weak sources, and giving only opinions about whether a technology is good or bad.
Ways to teach it
- Have students sort cards for selective breeding, GM crops, gene therapy, and animal husbandry by method, trait, benefit, and concern.
- Use the prompt, Should humans change inherited traits in organisms, and require one claim, two evidence points, and one tradeoff.
- Give three short source excerpts and ask students to mark each as reliable, questionable, or not useful with one reason.
- Compare seedless watermelon, disease-resistant corn, and dog breeds, then ask who benefited and what problems may have followed.
