HS-ESS3-4
The standard
Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.
Next Generation Science Standards
What this standard means
Students need to judge a technology meant to reduce human impact on ecosystems. They should use evidence, not opinions, to compare how well it works, what problem it targets, and what tradeoffs it creates. Data might include pollution levels, habitat loss, land use maps, species counts, or waste amounts.
Mastery looks like a clear claim supported by data, with limits and side effects named. Strong students can suggest a specific improvement and explain why it should help. Students often get stuck treating any “green” idea as automatically good, ignoring cost, scale, unintended harm, or weak evidence.
Ways to teach it
- Have students test simple water filters using gravel, sand, charcoal, and dirty water, then compare turbidity before and after filtering.
- Ask students to write: Which solution best reduces plastic waste at our school, refill stations, compostables, or bottle bans? Defend with evidence.
- Give students a one-page data table on two pollution-control designs and ask them to choose the better option in three sentences.
- Use a local landfill, solar farm, storm drain, or recycling program as a case study for benefits, tradeoffs, and possible improvements.
