Mississippi Science L.4.2.2
The Standard
- L.4.2
- Students will demonstrate an understanding of life cycles, including familiar plants and animals (e.g., reptiles, amphibians, or birds).
Develop and use models to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, or butterflies) including commonalities (e.g., birth, growth, reproduction, or death).

What This Standard Means
What Students Need to Do
- Students draw and use life cycle diagrams for plants and animals. They show how each organism grows, produces offspring, and dies. They compare stages that are alike and stages that differ.
What Mastery Looks Like
- A student puts the stages of a bean plant and a butterfly in the right order. Their arrows show that adults produce a new generation, not that the same organism starts over.
Common Misconceptions
- Students may think a caterpillar and a butterfly are different animals, or that plants do not reproduce. They may draw an arrow from a dead adult to an egg, as if that organism starts life again.
How to Assess It
- Give students frog and butterfly stage picture cards. Have them draw two labeled cycles, mark reproduction and death, and write one similarity and one difference.

Ways to Teach It
Give pairs bean seed, sprout, flower, and pod picture cards to arrange on a paper life cycle wheel with arrows.
Ask: How does a bean plant make a new plant, and how does a frog make a new frog? Use drawings to explain.
Shuffle frog and butterfly stage cards; teams race to sequence both cycles and point out where each organism grows and reproduces.
Show photos of eggs, caterpillars, and butterflies on milkweed; have students sketch how the butterflies produce the next eggs.
