Mississippi Science ZOO.2.9

ScienceGrades 9–12Zoology I and II

The Standard

ZOO.2: Students will understand the structure and function of phylum Porifera and phylum Cnidaria and how each adapts to their environments.

Describe the ecological importance of and human impacts on coral reefs.

2026 Mississippi College- and Career-Readiness Standards for Science · Phyla Porifera and Cnidaria

Teacher's field guide

What Students Need to Do: Students explain how reefs provide shelter for fish and reduce wave energy along coasts. They describe how warmer water, muddy runoff, and physical damage harm reefs and the animals that depend on them.
What Mastery Looks Like: Given reef photos and a water temperature chart, students connect bleaching to heat. They can predict how coral loss affects fish habitat and wave damage along a coast.
Common Misconceptions: Students may think coral is a plant or just a rock. They may assume bleached coral is already dead, though it can recover. They may also miss how runoff from land harms reefs.
How to Assess It: Exit ticket: A reef near a cleared hillside receives muddy runoff. Explain one effect on the coral and one effect on reef fish.

Lesson moves

In a shallow tray, push water toward a sand shore with and without a rock barrier; compare how much sand moves.
Show healthy and bleached reef photos; ask, "How might fewer living corals change where young fish hide?"
Match cards for warming, muddy runoff, anchors, and loss of grazing fish to bleaching, blocked light, broken coral, and algae growth.
Use a Florida Keys reef map and a hurricane photo to explain how reef loss could increase wave damage to nearby homes.
