Lesson Vocabulary

Producer

Roots

Stem

Fruit

Leaves

Flower

2

Producer

An organism that uses
sunlight to make its
own food for energy
through
photosynthesis

3

Stem

The stem supports the
plant and carries water
and nutrients to other
parts of the plant.

4

Leaves

The leaves are a part of
the plant that grows
from the stem and
makes food for the
plant .

5

Xylem

Tubes that carry water
from the roots to all
parts of the tree or
plant.

6

Roots

The roots grow
underground and take
in water and nutrients
from the soil.

Do Now

Madelyn is collecting rocks near a river.
She pours water over one rock and
notices that some water seems to
disappear into the rock. What does this
tell Madelyn about the rock?

A.

The rock has tiny spaces that hold
water.

B.

The rock is smooth and shiny on the surface.

C.

The rock is very heavy and does not break.

D.

The rock is made of metal and stays dry.

Santiago pours water over two different
rocks. One rock absorbs water quickly,
while the other does not absorb any
water. Which rock is more likely to collect
and store water underground?

A.

The rock that does not absorb water.

B.

The rock that absorbs water quickly.

C.

Both rocks collect water equally.

D.

Neither rock can collect water underground.

Interactions in Ecosystems

LO: SWBAT use models to
investigate and explain how
water moves from roots to
leaves in a producer.
DOL: Given scenarios, SW correctly use
models to investigate and explain how
water moves from roots to leaves in a
producer in at least 4 of 5 questions.

SCI.4.12A Investigate and explain how most producers can make their own food using sunlight, water, and carbon dioxide through the
cycling of matter;
SEPs 4.1A, 4.1D, 4.1E
RTCs 4.5B, 4.5D, 4.5F

Traveling Water: Exploring How Plants Drink

How do you think water travels from the roots (bottom) to the leaves (top)?

Predict what will happen when the celery
is placed in the colored water.

Observe how water moves up the fibers of the paper towel.

Traveling Water: Exploring How Plants Drink

What did you notice about the celery or leaves after it was in the water?

How is this similar to what happens in a
real plant?

What might happen to plants if they couldn’t get water to their leaves?

Plant Parts

Roots are part of the plant that grow
under the ground. The roots take in
water and minerals that the plant
needs.

Leaves are part of the plant that grow
from the stem. Leaves absorb
sunlight and make food for the plant.

The stem is a part of the plant that
holds up or supports the plant.

Match the parts of a plant with the correct definition of the plant part.

Roots Supports the plant and carries water

and nutrients to other parts of the plant

Grow underground and take in water

and nutrients from the soil

Grow from the stem and make food for

the plant

Leaves

Stem

Ethan notices that when he places flowers in colored water, the petals change color. What part of the plant is Ethan modeling in this experiment?

A.

The way flowers produce food.

B.

The way water moves to all parts of the plant.

C.

The way roots hold the plant in place.

D.

The way plants grow toward sunlight.

Kara compares two plant models. One uses a sponge and straws, and the other uses celery and colored water. How are these models similar?

A.

Both show how roots hold the plant in place.

B.

Both show how plants absorb sunlight for photosynthesis.

C.

Both show how leaves release oxygen into the air.

D.

Both show how water travels from the soil to the leaves.

DOL: Given
scenarios, SW
correctly use models
to investigate and
explain how water
moves from roots to leaves in a producer
in at least 4 of 5
questions.
