This document provides an overview of a grade 2 science review covering topics about plants and animals. It discusses key facts about plants like what they need to survive and plant traits. It also covers the different groups of animals like mammals, birds, reptiles and fish. The document explains life cycles of different animals and how animals adapt and find shelter in their habitats. Food chains and webs are defined and how habitats can change over time is described. Endangered animals and how fossils provide information about past habitats is also summarized.

1. Grade 2
Science Review
Term 1

2. Plants are living things.
• Plants need water, sunlight, air, water, space and
warmth.
• Plants get nutrients from the soil.
• Leaves take in air and sunlight to make food.
• The stem holds the plant up.
• The roots hold the plant in the soil and take in water.

3. Plant Traits
● The way plants look or act is called a trait. Plants get
many of their traits from their parent e.g. colour,
stem length, leaf shape.
● Some plants have many leaves, other plants have few
or no leaves.

4. How do plants survive in different
places?
● Plants in dry places have few or no leaves. They store
water in their stem.
● Plants in wet places have large leaves.
● Plants in windy places can bend.

6. Animals with a backbone:
1. Giraffe
2. Lion
3. Cat
4. Dog
5. Crocodile
6. Flamingo
7. Horse
Animals with no backbone:
1. Octopus
2. Starfish
3. Jellyfish
4. Caterpillar
5. Spider
6. Crab
7. Bee

7. Animal Groups

8. Mammals:
• Have hair or fur
• Have live babies
• Mothers make
milk to feed their
babies
• Are warm-
blooded

9. Birds:
• Have feathers
• Have wings and a
beak
• Lay eggs
• Are warm-blooded

10. Reptiles:
• Have hard skin or
scales
• Lay eggs
• Live on land or in
water
• Are cold-blooded

11. Fish:
• Have fins and
scales
• Live in water
• Lay eggs
• Breathe with gills
• Are cold-blooded

12. Amphibians:
• Have wet skin
• Live in water and
on land
• Have legs
• Are cold-blooded

13. Insects:
• Have 6 legs
• Hard outer shell
• Can walk or fly

14. How do animals grow and change?
● How an animal grows and changes is called it's
life cycle.

15. Life Cycle of a Panda

16. Life Cycle of a Chicken

17. Life Cycle of a Butterfly

18. How do animals survive?
1. Adaptation
An adaptation is a body part or a way an animal
acts.
● Giraffes have long necks that help them reach
leaves in the tops of trees.
● Camels have long eyelashes to protect their eyes
from the sand.
● Camels can close their nostrils to stop sand from
getting inside.

19. How do animals survive?
2. Camouflage
• Camouflage is a way that animals blend into their
surroundings. The colour or shape of an animal
helps it hide. Camouflage helps animals hide from
predators.

20. How do animals stay safe?
● Fish swim in a large group.
● Turtles stay safe by hiding in their shell.
● Skunks spray a bad smelling liquid to keep other
animals away.

21. What is a habitat?
● A habitat is a place where plants and animals live. In a
habitat animals find food, homes and the water they
need.
● Hot and dry (desert)
● Wet and grassy (rainforest/ jungle)
● Cold and snowy (polar)
● Grassy and warm (grasslands)

22. What do animals get from
their habitat?

23. Food Chains
• A food chain shows the order in which living things
get the food they need.
• Some food chains are on land. Some are in the water.
Some can be both on land and in water.
• Carnivores eat other animals.
• Herbivores eat plants.

25. Food Web
• A food web is two or more food chains that are
connected.

26. How Habitats Change
Describe how the habitat has changed:

27. How Habitats Change
• 1. Drought – little or no rain for a long
time
• 2. Fire
• 3. Flooding
• 4. People
• 5. Animals

28. Endangered
• When many of one kind of animal die and only a few are left,
that animal is endangered.
• Animals can become endangered when people hunt them or
build on their habitats.

29. Fossils
• A fossil is what is left of a living thing from the past.
• Scientists can learn about habitats of the past from the
plant and animal fossils they find.
• If a fossil does not match the habitat they were found in
then scientists can tell that the habitat has changed.
