SUMMARYThis book gives readers information about predicting earthquakes
and volcanic eruptions.
INTRODUCE THE BOOK
BUILD BACKGROUND Ask students what they know about natural disasters.
PREVIEW/USE TEXT FEATURES Direct students’ attention to the diagrams
and maps. Have them look at page 8 and ask them how this diagram is a
useful way to explain how a volcano erupts.
TEACH/REVIEW VOCABULARY Review the vocabulary words using a Word Knowledge Rating Chart. First, write each word on the board. Ask students to rate it: Know, Have Seen, Don’t Know. Then, write each word on the chart
under a head. After reading the book, review the ratings and make changes
based on revised understandings.
Review vocabulary with students and then ask questions that
involve them in the answer. For
volcanologist, ask: What are you called if
you study volcanoes? Do this with all words.
TARGET SKILL AND STRATEGY
COMPARE AND CONTRAST Remind students that when they
compare things they show similarities and differences, and when they
contrast things,
they just show differences. Discuss clue words such as
however, differently, similarly, and
but, and ask students to compare and contrast rain and snow
using these clue words.
MONITOR AND FIX UP Remind students that
monitoring their
comprehension means recognizing when the text stops making sense to
them, and
fix-up strategies are ways to help. Give students a graphic
organizer with the headings
if this happens and
then this will happen, and
suggest students fill it in as they read.
READ THE BOOK
Use the following questions to support comprehension.
PAGE 8 How does this diagram show what happens on all sides of a volcano? (Below is the earthquake, above are the gases, and there is a bulge on the
side.)
PAGE 9 What does magma mean here? Reread this page or look in the
Glossary, if necessary. (Magma means melted rock.)
PAGES 14–15 Compare and contrast volcanoes and earthquakes. (Compare:
Both are natural disasters. Both cause damage. Contrast: The exact time and
place of earthquakes cannot be predicted, but we can predict volcanic
eruptions.)
TALK ABOUT THE BOOK
READER RESPONSE
- Diagrams should show that students comprehend differences between
volcanic eruptions and earthquakes.
- By measuring changes in the slant of the ground, tiltmeters help
scientists predict volcanoes.
- Possible response: It was my fault the dog barked.
- Mt. Vesuvius in Italy and Mt. St. Helens in the United States
RESPONSE OPTIONS
WRITING Ask students to imagine they are scientists monitoring a volcano. Suggest they write a “To Do” list and give reasons for each item.
CONTENT CONNECTIONS
SCIENCE Suggest students do more research on famous
eruptions such as Vesuvius or Krakatoa.
