NGSS 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.

What This Standard Means
What Students Need to Do
- Students find trustworthy information about ways people influence which traits appear in plants, animals, or humans. They compare older methods, such as selective breeding, with newer tools, such as gene editing. They combine evidence from several sources to explain scientific and social effects.
What Mastery Looks Like
- Students can compare selective breeding, genetic modification, animal husbandry, and gene therapy. They can explain how each method changes genetic outcomes and identify likely benefits, risks, and social effects. They support conclusions with evidence from reliable sources.
Common Misconceptions
- Students may think selective breeding and genetic modification are the same process. They may assume all genetic changes pass to offspring, including gene therapy changes in body cells. They may also treat company claims or social media posts as reliable evidence.
How to Assess It
- Give students two short source cards about a genetically modified crop. Ask them to name the technology, explain its effect on inheritance, and cite one benefit or risk supported by evidence.

Ways to Teach It
Model selective breeding with colored beads, choosing parent pairs by one trait and tracking changes across five generations.
Write a claim on whether editing crops for drought resistance is worth the risks, using evidence from two source cards.
Play a matching game linking selective breeding, genetic modification, and gene therapy to tools, outcomes, benefits, and risks.
Compare a seed company page and a university article about pest-resistant corn, then mark claims supported by evidence.

Mastery here sets students up for these next.
- HS-LS4-2
Understanding inherited trait variation and selection in human-directed breeding supports explaining how variation and reproductive success drive evolution.
- HS-LS4-3
Understanding human selection of heritable traits supports the high school idea that advantageous traits can become more common in populations.
