Mississippi Science L.5.3B.1
The Standard
- L.5.3B
- Students will demonstrate an understanding of a healthy ecosystem with a stable web of life and the roles of living things within a food chain and/or food web, including producers, primary and secondary consumers, and decomposers.
Obtain and evaluate scientific information regarding the characteristics of different ecosystems and the organisms they support (e.g., salt, and fresh water, deserts, grasslands, forests, rain forests, or polar tundra lands).

What This Standard Means
What Students Need to Do
- Students gather information about conditions in different ecosystems, such as rainfall, temperature, and water type. They check where the information came from and use it to explain which organisms can live there.
What Mastery Looks Like
- A student uses a labeled rainfall chart to compare deserts and rainforests. They explain why a cactus is suited to a dry desert and point out when an unsupported claim conflicts with the chart.
Common Misconceptions
- Students may think deserts are always hot or that freshwater and saltwater habitats support the same animals. They may accept a claim about where an animal lives without checking its source.
How to Assess It
- Give students a rainfall chart credited to a science textbook and an unsigned card claiming deserts are wetter than rainforests. Ask which source is better supported and where a cactus and a fern would most likely grow, using evidence from the chart.

Ways to Teach It
Give pairs rainfall cards and organism pictures; have them build desert and rainforest displays and label one clue for each match.
Show a National Park Service fact sheet and an unsigned post about desert animals; ask which claims students can verify and how.
Play ecosystem match: teams pair organism cards with habitat cards and earn a point only when they cite a condition from the card.
Show a photo of a nearby pond and a cattail field-guide page; ask which pond conditions support cattails.
