Chapter 4:  How Living Things Grow and Change

Essential Question: 
How do plants and animals change as they grow?

Students will use knowledge about life processes to distinguish between living and nonliving things.  They will describe how organisms change as they grow and mature.  Students will learn that all living things have offspring that resemble their parents.

 Chapter 5:  Earth's Land, Air, and Water

Essential Question:  How do people use Earth's natural resources, and what are ways that people can take care of them?

Students will recognize that the solid materials making up the Earth come in all sizes, from boulders to grains of sand.  They know that life occurs on or near the surface of the Earth in land, air, and water.  Students know that the activities of humans affect plant and animals in many ways.

                     weathering     natural resources
                     sand              pollution
                     minerals         recycle

Chapter 3:  How Plants and Animals  Live Together

Essential Question: 
How do living things help each other?

Students will learn that plants and animals are dependent upon each other for survival.

Vocabulary:  producer                       consumer

                     food chain                     predator
                     prey                              food web

1. A producer is a living thing that can make its own food.  A green plant is a producer.

2. A consumer is a living thing that cannot make its own food.  All animals are consumers.

3. All living things need food.  Some animals eat plants.  Other animals eat those animals.  This is a called a food chain.

4. A predator is an animal that catches and eats another animal.

5. Prey is an animal that is caught and eaten.

6. Habitats usually have more than one food chain. The food chains in a habitat make up a food web.

1. A mammal is an animal with a backbone that usually has hair or fur on its body and feeds milk to its young.  Dog, cats, and horses are some kinds of mammals.

2. A bird is an animal with a backbone that has feathers, two legs, and wings.

3. A fish is an animal with bones that lives in water and has gills.

4. A reptile is an animal with bones that has dry, scaly skin.

5. An amphibian is an animal with bones that lives part of its life on land and part of its life in water.

6. Camouflage is a color or shape that makes an animal hard to see.  Some animals use camouflage to hide themselves from danger.

7. Gills are special body parts that get oxygen from water.  Fish have gills.

8. An insect is an animal without bones that has three body parts and six legs.

Chapter 1:  
All About Plants

Essential Question:  
How Do Plants Live in their Habitats?

Students will learn about the parts of plants; how seeds are scattered; how plants are grouped; and plant adaptations.

Vocabulary:  nutrients     flower
                     roots          environment
                     stem          adapted
                     leaves        prairie

Science Vocabulary
Chapter One:  All About Plants

1. Nutrients are materials that living things need to live and grow.  Many plants get nutrients from soil and water.

2. Roots are the parts of a plant that hold the plant in place and that take in water and nutrients from the soil.

3.  A stem is the part of a plant that holds it up and that carries water and nutrients to the leaves.

4.  Leaves are parts of a plant that use sunlight, air, nutrients, and water to make food for the plant.

5. The flower is the part of the plant that makes seeds.

6. The environment is all the things that surround a living thing.  A cactus is a plant that grows in a desert.

7.  Adapt means to change.  Living things have adapted or changed to live in their environment.

8.  A prairie is flat land covered with grasses and having few trees.
