Note from the author:
This formative is by Susan Castigliego! Below, she describes how each 3rd grade NGSS standard is assessed in it so you can see how it fits into what you are already teaching!

3-LS1-1 Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death. LS1.B: Growth and Development of Organisms Reproduction is essential to the continued existence of every kind of organism. Plants and animals have unique and diverse life cycles.

Students will learn that life cycles of both a plant and a frog have birth, reproductin, and death in common. Students will identify stages of a life cycle and read an article and answer question about life cycles.
3-LS1-1.Develop models to describe that organisms have unique and diverse life cycles but all have in common common birth, growth, reproduction, and death.


  • Understand that plants have a life cycle that includes sprouting; developing roots, stems, leaves, and flowers; reproducing; and eventually dying
  • Observe the changes that occur during plant growth and development
  • Sequence the stages of plant life
Read the passage below about plant life cycles.
Many plants start their life cycles as a seed. The
seed needs certain things or it will not grow into a
plant. Sometimes seeds wait in the ground until they
can get the things they need. They wait for warmth
from the sun. They wait for water. When they have
what they need, they start to grow. A tiny little sprout
will push out of each seed. The sprouts stretch up until
they poke through the dirt and into the air.
The plants continue to grow when they get
sunshine and water. The stems grow taller and leaves
unfold. More leaves and stems grow on the main
stems. The adult plants grow flowers. The flowers of
many plants make fruit. The fruit has seeds inside it so
more new plants can grow.
New plants look like their parent plants. Seeds
from a parent plant will grow into the same kind of
plant as the parent. When a seed begins to grow, it is
the beginning of another plant life cycle

Living organisms go through a series of changes called the life cycle. They begin life, they grow, they ____________________, they get older, and die.
A reproduce
B metamorphosis
C fruit
Explain Metamorphosis in your own words.
Explain what life cycle means in your own words.
Explain the sequence in the stages of th elife cycle of a plant.
Based on the above diagram, what two things does a seed in the ground need to have in order to grow?
How do many plants begin?
What kind of plant would a seed grow into?
Where can you usually find seeds in an adult plant?
The life cycle of a plant and the life cycle of a frog are different. However, they both have things in common. Explain what is the same about both organisms life cycles. You can make a t chart below to list the similarities and the differences
