Mississippi Science L.2.2.1
The Standard
- L.2.2
- Students will demonstrate an understanding of how living things change in form as they go through the general stages of a life cycle.
Use observations through informational texts and other media to observe the different stages of the life cycle of trees (i.e., pines, oaks) to construct explanations and compare how trees change and grow over time.

What This Standard Means
What Students Need to Do
- Students use photos and short texts to put oak and pine life stages in order. They explain how each tree grows from a seed and compare the changes they see.
What Mastery Looks Like
- A student can order seed, seedling, sapling, and mature tree pictures for both oaks and pines. They can explain that both grow larger, while oaks make acorns and pines make seeds in cones.
Common Misconceptions
- Students may think a pine cone is a seed, rather than something that holds seeds. They may think an oak that loses its leaves in fall has died. They may mistake a sapling for a different kind of tree.
How to Assess It
- Give students picture cards showing an acorn, an oak seedling, a mature oak, a pine seed from a cone, a pine seedling, and a mature pine. Ask them to sequence each tree and name one similarity and one difference.

Ways to Teach It
Set out an acorn, a pine cone, and tree photo cards; have pairs build two life cycle lines and mark where seeds begin.
Show young and mature oak and pine photos; ask, "What changed, and which details in the pictures show it?"
Play a picture-card relay: teams place oak and pine life stages in order, then explain one card placement.
Take students outside with acorn and pine cone photos; ask them to find a place where a fallen seed could sprout.
