Mississippi Science ENV.1.1
The Standard
- ENV.1
- Students will investigate the interdependence of diverse living organisms and their interactions with the components of the biosphere.
Identify, investigate, and evaluate the interactions of the abiotic and biotic factors that determine the types of organisms that live in major biomes.

What This Standard Means
What Students Need to Do
- Students compare rainfall, temperature, soil, and organisms across major biomes. They use evidence to explain how those conditions and relationships among organisms affect which species live there.
What Mastery Looks Like
- Given two biome profiles, a student can predict which plants and animals are likely to survive in each and cite evidence. They can trace how rainfall affects plant growth and herbivores, then explain how grazing might change the plants.
Common Misconceptions
- Students often assume temperature alone determines a biome, ignoring rainfall and soil. They may treat animals as passive residents rather than organisms that can change plant cover and food supply.
How to Assess It
- Exit ticket: A site gets 15 cm of rain yearly and has sandy soil and sparse shrubs. Name its likely biome, then explain how increased rain and grazing could change plant cover.

Ways to Teach It
Pour 50 mL of water into perforated cups of sand and potting soil, measure drainage, and predict which seedlings might dry out first.
Display monthly rainfall graphs for a savanna and rainforest; ask, “How might drought and browsing together limit savanna trees?”
Give groups cactus, oak, and moss cards with desert, temperate forest, and tundra climate cards; require a match supported by climate evidence.
At the schoolyard, compare plant counts and ground temperature in sun and tree shade, then explain how trees change conditions for smaller plants.
