Integrate Visual and Verbal Information
Practice
Write your answers and then print these pages.
1. Read each text.
2. Look at the visual element that goes along with it.
3. Integrate the information in the visual element with the information in the text by
answering the question that follows.
#1: FLOWCHART
Your digestive system is made up of five major organs: the mouth, esophagus,
stomach, small intestine, and large intestine. Suppose you decide to eat a sandwich
for lunch. In your mouth, your teeth break apart and grind your sandwich into
smaller bits. When you swallow, the food travels down your esophagus to your
stomach. Your stomach holds the food you ate for about four hours. During
this time, muscles in your stomach break down the food into smaller pieces. By
the time the food enters your small intestine, it is a liquid. Most nutrients are
absorbed into your blood. Then digested food goes into the large intestine. Water
returns to the body. Solid waste leaves the body.

#2: DIAGRAM
Read the passage and look at the diagram below.
In the 1800s, an Austrian monk named Gregor Mendel experimented with pea plants to
study how traits are passed from parents to their offspring.
First, Mendel selected pea plants that had been bred to always express the trait he
was studying. Organisms that always produce offspring with the same traits are known as
purebred. For example, a purebred tall pea plant will produce only tall offspring.
Next, Mendel crossed tall pea plants with short pea plants. This cross produced hybrids,
organisms that have inherited two different forms of the same trait, one from each parent. In
this case the hybrid offspring each received a tall (T) and a short (t) form for the trait of height.
Surprisingly, when Mendel looked at the hybrids from this cross, every one of them was tall. Why
were all the offspring tall? What happened to the short trait?
Mendel asked these same questions. He believed that the trait for shortness must
have been present but that it was somehow hidden. He tested this hypothesis in a second
experiment. Mendel allowed the hybrids to self-pollinate. Their offspring included tall plants
and short plants.

Mendel’s experiment showed that the tall form was more dominant than the short form.

Now integrate the information you learned from the written text and from the
diagram.
3. Are the two tall parent pea plants shown on the left of this diagram purebred plants or
hybrids? Explain how you can tell.
4. How can you tell that the tall form is more dominant than the short form?
#3: MODEL
A model is a representation that contains the essential structure of some object or event in the
real world. Scientific models are based on the knowledge and understanding that scientists
have about the world.
Plants make their own food in structures inside their cells called chloroplasts.
A chloroplast is a green structure where the energy from sunlight is used to
produce food for the plant. Chloroplasts are green because they contain a chemical
called chlorophyll. Chlorophyll is able to use the energy in sunlight.
Many plant cells are green because of the chlorophyll in their chloroplasts.
Plant cells that lack chloroplasts are not green. Chloroplasts are mainly found in
the cells of leaves and stems of plants.

#4: GRAPH
Read the passage and look at the graph below.
If you know the speed of an object and the direction in which it is moving,
then you know the object’s velocity. Velocity is a description of a moving object’s
speed and direction. When you know the velocity and present position of an
object, then you should be able to predict where it will be located after a certain
amount of time.
If an object travels in a straight line at a steady speed, its velocity is constant.
Any change in speed or direction of an object causes its velocity to change.
Acceleration is a change in the velocity of an object over time.

#5: TABLE
Read the passage and look at the table below.
Thermal conductivity is the ability of a material to transfer heat. If a material
conducts heat easily, it is a good thermal conductor. If a material conducts heat
poorly, it is a good thermal insulator. Most metals are thermal conductors, and
most nonmetals are thermal insulators.
