Mississippi Science ENV.2.6
The Standard
- ENV.2
- Students will relate the impact of human activities on the environment, conservation activities, and efforts to maintain and restore ecosystems.
Enrichment: Obtain water from a local source (e.g., stream on campus, rainwater, ditch water) to monitor water quality over time, using a spreadsheet program to graphically represent collected data.

What This Standard Means
What Students Need to Do
- Students collect water from the same local source on several dates. They measure pH and temperature the same way each time, then enter and graph the readings in a spreadsheet.
What Mastery Looks Like
- A student records the site, date, pH, and temperature for each sample. They make labeled graphs and describe a change the readings show without claiming to know its cause.
Common Misconceptions
- Students may switch collection spots and treat the readings as directly comparable. They may call one unusual reading a trend or assume clear water is safe to drink.
How to Assess It
- Enter these readings in a spreadsheet: Oct. 1, pH 7.0; Oct. 8, pH 6.8; Oct. 15, pH 6.5. Make a labeled line graph and write one observation it supports and one cause it cannot confirm.

Ways to Teach It
Test teacher-collected creek water with pH strips and a thermometer, then enter the date, site, and readings in a shared spreadsheet.
Show readings from before and after rainfall, then ask: What changed, and why does the graph alone not prove rain caused it?
Give pairs a spreadsheet with four weeks of readings, and have them fix mislabeled axes and a missing data point.
Check the local water utility's quality report and list one test it runs that your classroom pH strips cannot replace.
