Mississippi Science L.2.2

L.2.2 is a cluster heading. These are the individual standards under it.

• L.2.2.1

  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 explana...

• L.2.2.2

  Construct explanations using first-hand observations or other media to describe the life cycle of an amphibian (birth, growth/development, reproduction, and dea...

01

What Students Need to Do

Students use pictures, short texts, and observations to put oak, pine, and frog life stages in order. They explain how each living thing changes as it grows. They describe how adults produce young and eventually die.

02

What Mastery Looks Like

A student can show how an acorn becomes an oak and how a pine seed becomes a pine tree. They can describe how frog eggs become tadpoles, froglets, and adults. They use a picture or observation to explain one difference between oak and pine growth.

03

Common Misconceptions

Students may call a pinecone a seed or think an acorn can grow into a pine. They may mistake a tadpole for a fish. Some leave death out of a life cycle because adults can produce young.

04

How to Assess It

Give students picture strips showing oak, pine, and frog life stages. Ask them to order each strip, write one difference between the trees, and explain what adult frogs do before they die.

1. 01

   Give pairs acorns, pinecones, and tree-stage photos; have them match each object to its adult tree and order the photos.

2. 02

   Show photos of a frog egg, tadpole, froglet, and adult; ask, 'What changes, and how do you know it is the same animal?'

3. 03

   Play a life cycle relay with oak, pine, and frog picture cards; students sequence a set and explain one change.

4. 04

   Show photos of an oak and pine beside a sidewalk; have students draw where fallen seeds could grow into seedlings.

• L.4.2

  Students will demonstrate an understanding of life cycles, including familiar plants and animals (e.g., reptiles, amphibians, or birds).

• L.K.1A

  Students will demonstrate an understanding of living and non-living things.

• L.K.2

  The Kindergarten version of this standard.

• L.1.2

  Students will demonstrate an understanding of how living things change in form as they go through the general stages of a life cycle
