Text Features (6.0)
Materials:

  • Secrets from the Ice (one copy per student)

  • Planet in Distress (one copy per student)


Description:

Informational texts often have special features to highlight or explain important points or ideas. Three of these features are graphs, charts, and diagrams.


Step-by-Step:

1. Give participants copies of the text.

2. Tell participants that text features help students comprehend informational text.

Text features may include maps, charts, graphs, time lines, tables, and diagrams.

3. Tell participants to scan the text and identify examples of text features.

4. Tell participants, “Graphs are drawings that show relationship between numbers

or amounts, often over periods of time. Graphs may show a change or trend that

is important to understand a point in the text.”

5. Ask participants to open Planet in Distress to page 6. Tell participants, “Look at the

graph at the bottom of the page. Examine the graph. What conclusions can you

draw from it? (The graph shows how global temperatures are rising over time.)

6. Ask participants to read the text on page 6. Ask, “What further conclusions can be

drawn from the graph?”

7. Tell participants, “Another text feature found in informational text is a diagram.

Diagrams are drawings or photos that show how things work or how they are

constructed. They are usually labeled and provide information important to

understand the text.”

8. Ask participants to open Secrets from the Ice to page 27. Say, “Read the text

caption, then examine the diagram. How does the diagram help you understand

the text?” (The diagram shows how the scientists use the layers of the Vostok ice

core in Antarctica to indicate climate changes over a period of 140,000 years. By

studying the color key, you can see at a glance how the temperatures in Antarctica

changed through the years.)

9. Ask participants to turn to page 17. Read the labels and caption aloud. Say, “What

information is gained from this diagram? How does the glacier fit inside the

volcano?”

10. Tell participants, “Charts are another source of facts in informational text. Charts are

tables with or without pictures.”

11. Ask participants to open Secrets from the Ice to page 7. Say, “The chart shows the

percentage of air at each stage as snow turns into glacial ice. At a

glance I can see that snow has 85 to 90 percent air, and blue ice has less that 20

percent air.”

12. Ask participants to turn to pate 11. Say, “What is explained by this chart? How does

it help you understand Agassiz’s theory of an Ice Age?”

13. Ask participants to recall the three text features. Using the text, ask them to create a

graph, chart, or diagram to enhance the information in the text.

Assessment Activity Title:

Create a Feature


Description of Activity:

1. Discuss text features of informational text, such as graphs, charts, and

diagrams. Ask students to identify examples of these text features from

Planet in Distress and Secrets from the Ice.

2. Tell students that graphs are drawings that show the relationship between

numbers or amounts, often over periods of time. They may show a change

or trend that is important to understand a point in the text.

3. Have students open Planet in Distress to page 6. Direct their attention to

the graph at the bottom of the page. Ask them to examine the graph and

decide what conclusions can be drawn from it. After looking at the graph,

have students read the text on page 6. Ask what further conclusions they

can draw from the graph.

4. Next explain that diagrams are drawings or photos that show how things

work or how they are constructed. They are usually labeled and provide

information important for understanding the text.

5. Have students open Secrets from the Ice to page 27. Explain how the

diagram on this page provides important information to enhance the

information provided in the text. Next, have students turn to page 17.

read the labels and caption aloud. Ask students to explain the

information gained from this diagram.

6. Tell students that another source of facts in informational text is the

chart. Charts are tables with or without pictures. They present

information visually to help the reader understand the text.

7. Have students open Secrets from the Ice to page 7. Explain how the

chart adds to the information in the text. Next, have students turn to

page 11. Ask students to explain what is explained by the chart. How

does It help you understand Agassiz’s theory of an Ice Age?


8. Ask students to compare the three text features from the lesson. Using

a social studies or science textbook students will use the information to

create a graph, chart, or diagram to enhance the information provided.


Assignment Extensions:

1. Planet in Distress (graphs) Using the data on page 8, students create

their own graphs demonstrating how much sea levels have risen recently,

and how much they may rise in the future.

2. Secrets from the Ice (diagrams) Have students construct a diagram to

explain a concept in the book for which there is no diagram.

3. Secrets from the Ice (charts) Have students create a two-column chart

representing the scientists featured in this book and their theories and

accomplishments.
