Mississippi Science L.2.2.2
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.
Construct explanations using first-hand observations or other media to describe the life cycle of an amphibian (birth, growth/development, reproduction, and death). Communicate findings.

What This Standard Means
What Students Need to Do
- Students use frog photos, video, or their own observations to explain how eggs become tadpoles, froglets, and adults. They explain that adults can reproduce and frogs eventually die, then share what they found in words or pictures.
What Mastery Looks Like
- Students put the life stages in order and show how new eggs begin another generation. They use a visible detail, such as growing legs, to explain a change.
Common Misconceptions
- Some students think tadpoles are fish, not young frogs. Others think eggs hatch into tiny adult frogs or that frogs die as soon as they lay eggs.
How to Assess It
- Give students pictures of frog eggs, a tadpole, a froglet, and an adult. Ask them to order the pictures, add arrows for new eggs and eventual death, and name one visible change.

Ways to Teach It
Give pairs clay and frog photos; have them model eggs, a tadpole, a froglet, and an adult.
Show tadpole and frog photos; ask, "What changed, and what in the photos shows you that?"
Give teams frog stage cards and a death card; have them order the cards and draw an arrow from adult to new eggs.
Show a pond video with frog eggs or tadpoles; have students spot a stage and predict the next visible change.
