__________________________________________________

slide7

Living things need nonliving things.

  • Plants need air, water, and light to grow.
  • People and animals need air, food,
  • and water to remain living.
  • Air, water, light and food are not alive……
  • so they are nonliving things.
  • Without nonliving things, living things could not survive. They would DIE.
slide8

THINK ABOUT IT

  • How are all living things alike?

All living things need food, air, and water.

Living things also grow and change.

  • How do living things use nonliving things?

Plants use air, water, and light to grow.

People and animals use air, water, and food to live.

LESSON 2

HOW DO PLANTS CHANGE AND GROW?

slide10

Plants need light, air, and water

  • to change and grow.
  • Plants also need nutrients.
  • Nutrients are mineralsfound in the soil.
  • Each part of the plant helps the
  • plant get what it needs to grow
  • and change.
slide11

PARTS OF A PLANT

FLOWER

SEEDS

____________

LEAVES

STEM

ROOTS

slide12

JOBS OF THE PLANT PARTS

  • seeds

---- a baby plant

  • flower

----makes seeds

  • leaves

---- use light, air, and nutrients

to make food

  • stem

---- holds up plant; moves water

and nutrients through the plant

  • roots

---- hold plant in soil; take in water

and nutrients from the soil

slide13

PARTS OF A SEED

Seeds have different parts. Each

part helps the seed grow a new plant.

TINY PLANT

----uses stored food

to grow

STORED FOOD

SEED COAT

----protects the seed

slide14

HOW PLANTS GROW FROM SEEDS

A seed will begin to germinate, or grow, when it

gets water and warmth.

2. First, the roots grow down.

3.Then, a stem grows up.

(**This young plant is called a seedling.**)

4. The seedling continues to grow and change.

It makes more leaves and stems. It gets

taller and thicker.

When fully grown, its flowers make fruits that hold seeds.

slide15

THINK ABOUT IT

  • What happens when a seed germinates?

When a seed germinates, it begins to grow.

The roots begin to grow down and the stem

grows up.

  • What are some ways plants may change?

Plants change as they grow. They get larger, grow more stems and leaves, get thicker, and produce flowers or fruits that make seeds.

slide16

LESSON 3

HOW ARE PLANTS ALIKE AND DIFFERENT?

slide17

Plants live in almost every part of the world.

Different kinds of plants grow in different

places.

Oak Forest

Desert

Pine Forest

slide18

A pine tree has leaves that

look like needles.

Its seeds grow in cones.

slide19

An oak tree has leaves that are broad and flat.

Oak trees grow from seeds inside acorns.

slide20

A cactus grows in a desert. It stores water in its thick stems.

Its leaves are sharp spines. The spines protect the cactus

from animals that might eat it.

  • Cactuses flowers grow into fruit.
  • The seeds of the cactus are inside the fruit.
slide21

THINK ABOUT IT

  • What are some places plants live?

Some of the places plants live are pine

forests, oak forests, and deserts.

  • How are plants in different places alike
  • and different?

All plants are living things. They all need air, water, light, and nutrients. Plants that grow in different places may look different, and have different kinds of stems, leaves, and seeds to help them live and grow.
