Mississippi Science ENV.2.5
The Standard
- ENV.2
- Students will relate the impact of human activities on the environment, conservation activities, and efforts to maintain and restore ecosystems.
Research various resources related to water quality and pollution (e.g., nonfictional text, EPA’s Surf Your Watershed, MDEQ publications) and communicate the possible effects on the environment and human health.

What This Standard Means
What Students Need to Do
- Students use water quality reports and other reliable sources to identify a pollutant, where it may come from, and how it reaches water. They explain possible effects on aquatic life and human health using evidence from those sources.
What Mastery Looks Like
- A student can use a nitrate test result to explain how runoff may lead to algae growth and lower oxygen for fish. They can describe the risk to infants if nitrate reaches drinking water, without claiming a stream test proves tap water is unsafe.
Common Misconceptions
- Students may assume clear water is safe or that pollution in a stream always reaches household taps. They may treat one test result as proof of where the pollution came from.
How to Assess It
- Exit ticket: A stream report shows high nitrate downstream of farms. Explain one possible effect on fish and one possible health risk if the water enters a drinking supply.

Ways to Teach It
Build a sloped tray watershed with paper farms, sprinkle cocoa on one slope, pour water, and watch runoff reach a model stream.
Compare a local water report with an EPA pollutant fact sheet, then write two sentences separating measured pollution from possible health effects.
Sort cards labeled fertilizer, runoff, nitrate, algae, low oxygen, and fish deaths into a cause-and-effect chain, then explain each link.
Find a public water utility's annual water report, circle one measured contaminant, and compare its level with the listed limit.
