Mississippi Science ENV.1.2
The Standard
- ENV.1
- Students will investigate the interdependence of diverse living organisms and their interactions with the components of the biosphere.
Evaluate evidence in nonfiction text to explain how biological or physical changes within biomes affect populations and communities and how changing conditions may result in altered ecosystems.

What This Standard Means
What Students Need to Do
- Students read nonfiction reports and graphs about changes such as drought or invasive species. They use evidence to explain effects on one population, other species, and the ecosystem. They check whether the evidence supports the claimed cause.
What Mastery Looks Like
- A student can use before-and-after counts to explain how a smaller pond might affect frogs and the snakes that eat them. They can also explain why the counts alone do not rule out disease.
Common Misconceptions
- Students may confuse a population with a community. They may assume every species responds the same way, or that two changes happening together prove cause and effect.
How to Assess It
- Give students this report excerpt: “During a drought, pond area fell by half, and frog counts fell from 80 to 30.” Ask them to explain one possible effect on other species and why these numbers alone do not prove drought caused the decline.

Ways to Teach It
Give pairs a printed pond report and frog-count graph; have them arrange drought, pond size, frogs, and snakes cards into a cause-and-effect chain.
Read a printed pond report, then ask: “Which sentence links drought to frogs, and what other cause could explain the counts?”
Play evidence match: teams pair claims about a shrinking pond and its wildlife with supporting lines from the printed report.
Compare a local drought map with nearby pond observations on iNaturalist, then discuss why sightings alone cannot show population size.
