Grade 2 Science Section 2 Study Guide
 There are different kinds of animals, they can be grouped by their types.
 Birds have feathers, wings, beaks, they hatch from eggs.
 Reptiles have dry skin, or scales. Cold blooded animals. They hatch from eggs.
 Mammals have babies, fur or hair, breathe air and drink milk from their mothers.
 Amphibians live in both water and on land. Usually start in the water and live on
land as adults. They have smooth, wet skin.
 Fish have scales, gills, fins, and backbones. They live in the water their whole
lives.
 We can group animals by where they live (their habitat), if they have backbones or not,
what they eat (meat or vegetables).
 Vertebrae are the bones in your back, also known as a backbone. Vertebrates are animals
with skeletons and a backbone.
 Invertebrates are animals with no back bone, like insects, crabs, spiders etc.
 All living things have basic needs, all living things need air, water, shelter, and space to
live and grow.
 Insects have three main body parts, the head, thorax (where the legs and wings might be
attached) and body. Insects always have six legs.
 Spiders are NOT insects, spiders are arachnids. Spiders have 8 legs and no backbones.
 Some animals use their color or shape to make them hard to see. This is called
camouflage, they use camouflage to protect themselves and hide from predators.
 Plants have many parts, leaves, stems, roots, some have flowers, fruits, and seeds.
 Flowers have pollen and nectar for bees and butterflies to eat.
 Most plants grow from seeds, which often grow in fruit.
 Leaves are green and help the plant turn Sun energy into energy for the plant.
 Stems help hold the plant up, and move nutrients and water through the plant.
 Roots are in the soil, they help hold the plant into the soil. Roots help take water
and nutrients from the soil to the stem.
 Dinosaur bones are a kind of fossil. They are petrified bones, petrified means that the
bones have turned to stone / rock after a long time in the ground.
 Animals use their special parts to do things. Birds use their wings to fly, their talons to
catch food, their beaks to catch food. Horses use their legs to run. Animals use their teeth
to chew. Turtles use their shells to protect themselves.

 A habitat is place where plants and animals live.
 A desert is hot and dry, living things have adapted to live in a dry habitat. Like
cactuses, scorpions, camels and spiders.
 An ocean is under the sea, it is salty water. Many animals and plants live in the
ocean like coral, fish, octopuses, whales and sharks.
 A forest is a place with many trees & animals like rabbits, birds, owls, and deer.
 A rainforest is a forest that is a jungle with huge trees, a canopy, lots of rain and
many special animals and plants. They are near the equator, so it’s usually hot.
 A wetland is an area with a lot of water, it’s fresh water. Lots of fish, animals and
birds live there. A swamp is a wet land.
 Plants need sunlight, water, air, and nutrients to live and grow.
 Fossils are a print or a part of an animal or plant that lived a long time ago. Fossils teach
us about how the Earth has changed over time. A fish fossil found in a desert means that
there was a lot of water there a long time ago.

An animal group that spends part of its life in the water and part on
land. Like frogs, toads, and salamanders. With smooth wet skin.
An animal group that has babies that drink their mother’s milk. They
have hair and breathe air. They are vertebrates, or have backbones.
An animal group that lives in the water and breath using gills. They
have scales, fins, and tails.
An animal group that has wings, a beak and talons. They usually have
feathers. They lay eggs and hatch from them.
An animal group that has dry scaly skin. They are cold blooded and
hatch from eggs that they lay.
A color or shape that makes an animal hard to see.
A food material that living things need to live and grow.
Grow down into the soil. Roots hold the plant into the soil. Roots
take nutrients and water to the stem.
Carries water and nutrients to the leaves and holds the plant up.
Green leaves take in sunlight and air to make food for the plant.
A place where animals & plants live, they can be hot, cold, wet, or dry.
Shows how the energy passes from one living things to another. Such
as from the sun, to plants, to small animals to larger animals.
An animal that hunts, catches, and eats other animals for food. Like
lions, wolves, and snakes.
The animal that is hunted and eaten by the predator. Like rabbits,
mice, snakes and insects.
A print or a part of a plant or animal that lived a long time ago.
A plant or animal that no longer lives on Earth. There are 0 of them
alive on Earth now.
