Plant and Animal Life Cycles

Our learning goal
I can describe how a bean plant, an elephant, a cheetah and a chicken grow and change in their life cycles.
This item has no instructions
What words do you know about life cycles?
Use this to surface simple prior knowledge such as grow, baby, seed, egg, plant and animal.
Plant Life Cycles
All of the stages of a living thing's life make up its life cycle.
This item has no instructions
A Bean Plant Begins
A bean plant grows from seeds.
When a bean seed gets the things it needs, it starts to grow into a small plant called a seedling.
This item has no instructions
The Seedling
A seedling has roots and leaves.
The seedling grows into an adult plant.
This item has no instructions
The Adult Bean Plant
An adult bean plant will develop flowers and fruits.
The flowers and fruits produce the seeds from which new plants can grow.
This item has no instructions
How the Bean Plant Changes
The bean plant grows and changes as it gets older by getting taller and the leaves getting bigger.
The bean plant also changes as it gets flowers, fruits and seeds.
This wording follows the provided answer in the attached page notes and keeps to the order of the source material.
What does a bean plant grow from?
eggs
seeds
flowers
roots
Checks the first stage of the bean plant life cycle.
Bean plant life cycle
A bean plant grows from seeds. When it starts to grow, it becomes a seedling. An adult bean plant makes flowers, fruits and seeds.
The blanks follow the order taught: seeds, seedling, then seeds again from the adult plant.
Animal Life Cycles
Mammals are animals such as elephants and cheetahs.
This item has no instructions
Mammal Life Cycle
A female adult elephant gives birth to a baby elephant.
The baby elephant looks like its mother.
This item has no instructions
Baby Elephant
It has four legs, a trunk and a tail.
The baby elephant gets bigger and taller as it grows.
This item has no instructions
Growing Elephant
It looks more and more like its mother.
As an adult elephant, it will produce new young of its own.
This item has no instructions
Cheetah Life Cycle
A female adult cheetah gives birth to live young.
The young look similar to their parents.
This item has no instructions
Growing Cheetahs
The young grow and change as they get older.
As they grow, they look more and more like their parents.
This item has no instructions
Adult Cheetahs
As adult cheetahs, they will produce new young of their own.
This item has no instructions
Which animal gives birth to a baby elephant?
adult elephant
adult chicken
bean plant
adult cheetah
Checks understanding that elephant young are born from an adult female elephant.
Mammal life cycles
A baby elephant looks like its mother. It gets bigger and taller as it grows. Young cheetahs look similar to their parents.
Focuses on the shared idea in the mammal slides: the young look like the adults and grow bigger.
Chicken Life Cycle
Chickens reproduce by laying eggs.
A newborn chicken, called a hatchling, hatches from each egg.
This item has no instructions
Hatchling
The hatchling has the same body parts as its parents.
The hatchling grows into a chick.
This item has no instructions
From Chick to Adult
The chick grows into an adult chicken and will produce offspring of its own.
This item has no instructions
What hatches from a chicken egg?
seedling
baby elephant
hatchling
adult chicken
Checks the key vocabulary from the chicken life cycle slides.
Chicken life cycle
Chickens reproduce by laying eggs. A newborn chicken is called a hatchling. The hatchling grows into a chick, and then an adult chicken.
Keeps the exact order from the chicken slides: eggs, hatchling, chick, adult.
What is one thing you learned today?
Students may mention that plants start from seeds and animals start as babies or from eggs, and that living things grow into adults.
Which life cycle was easiest to remember?
Encourage students to reflect on which example helped them most: bean plant, elephant, cheetah or chicken.
