Mississippi Science ZOO.4.8
The Standard
- ZOO.4
- Students will describe the evolution of structure and function of phylum Platyhelminthes, phylum Nematoda, and phylum Annelida.
Enrichment: Use an engineering design process to design and construct a system to utilize flatworms, roundworms, or annelids to meet a human need. *

What This Standard Means
What Students Need to Do
- Students choose a human problem worms can help solve, such as food waste. They set design limits, build a system, test it, and change it based on the results.
What Mastery Looks Like
- A student builds a compost bin that gives earthworms air, moisture, and suitable food. They compare scrap mass with a no-worm bin, then use the results to explain a design change.
Common Misconceptions
- Students may think any worm can compost scraps, including parasitic roundworms. They may seal the bin to keep moisture in or add meat, which can harm worms and attract pests.
How to Assess It
- Ask students to sketch a bin for composting cafeteria apple peels. Have them label how worms get air and moisture, name one result to measure, and suggest a change if scraps grow mold.

Ways to Teach It
Teams build a worm bin from a ventilated tub, damp shredded paper, vegetable scraps, and composting earthworms.
Ask, “Why would earthworms work better than parasitic roundworms in a cafeteria scrap bin?” Have students support their answer with two facts.
Give teams three bin cards with different air holes, moisture levels, and foods; have them rank the designs and revise one.
Weigh one day's cafeteria vegetable scraps, then use a provided bin capacity to estimate how many worm bins the school would need.
