HOW SEA TURTLES GROW AND CHANGE STUDY SHEET

Plants and animals are living things that need food and water. Animals can move but plants

cannot. Both are able to become parents.

Sea turtles live in the ocean but the females return to the each where they were born to lay their

eggs. The dig holes with their flippers, lay eggs in a hole, and cover the hole with sand. A female turtle

can lay as many as 200 eggs at one time. Most of the eggs won’t make it.

Sea turtle Flipper Sea turtle laying eggs Baby sea turtles are called hatchlings. After about 2 months the hatchlings use a special tooth to

break through the egg. It takes them from three to seven days to dig their way to the surface. Hatchlings

then quickly move towards the ocean.

Sea turtles are endangered. This means that there are very few of them and that they’re almost extinct.

LIFE CYCLE OF A DRAGONFLY STUDY SHEET

Insects have life cycle that are different from other animals.

Nymph- A young insect that looks like its parent but has no wings. Nymphs hatch from

eggs. They shed (molt) their outside covering many times as they grow. When they

become adults, they have wings to fly.

Dragonflies usually lay their eggs in the water.

A nymph hatches from the dragonfly eggs and lives in the water for a short time. After a

while, the nymph crawls to the land.

The nymph will shed its outer covering (molt) many times and grow wings before it

becomes an adult.

Dragonflies eat mosquitoes, water fleas, and almost any other flying insect.

LIFE CYCLE OF A HORSE STUDY SHEET

A horse is a mammal. Most young mammals grow inside their mothers. Young

mammals get milk from their mothers after they’re born.

A young horse is called a foal. Male (boy) foals are called colts and female foals

are called fillies. Both of them get milk from their mother for about 6 months.

Foals start to look more like their parents as they grow.

A horse is considered an adult when it turns about 5 years old. It is then old enough to

have foals of its own.

THE LIFE CYCLE OF A BEAN PLANT STUDY SHEET #1

Seeds contain an embryo (tiny plant) and stored food. The seed sprouts and uses the stored food

to grow up and out of the ground. Then it can begin to make its own food through photosynthesis. The

stored food in the seed gives it energy to germinate and become a seedling with leaves. It will then be able

to make its own food.

Seed coat- A hard outer covering that protects the seed.

Embryo- The small plant that can be found inside the seed.

Germinate- To begin to grow into a young plant. As seeds germinate, roots grow down into the ground

and a stem grows up towards the Sun.

Seedling- A young plant.
