determine the meaning
of unfamiliar words.

INTRODUCE

Discuss the dictionary strategy for unfamiliar words strategy using the steps on p. 382.

TEACH

Have students read "The Active Earth," paying attention to how vocabulary is used.
Model using a dictionary to determine the meaning of chimney.

MODEL I know the word
chimney begins with a ch. So
I find the dictionary page that has words that begin with ch. The third and fourth letters in the word are i, m. So I find the place in the dictionary having words beginning with chim to find chimney.

Whole Group Discuss the Question of the Day. Then use pp. 382–384.

Vocabulary Strategy

Read “The Active Earth.” Use a dictionary to find the meanings of the vocabulary words.

Try that meaning to see if it makes sense.

Read the entry for the word. If the word has
more than one meaning, decide which meaning you think fits in the sentence.

Use the guide words at the top of the pages to find the page that has the word.

Look at the first letter in the word.

Turn in the dictionary to the section for that letter.

Dictionary You can use a dictionary to find the meaning of an unfamiliar word. A dictionary gives words and their meanings, as well as other information about the words. The words in a dictionary are listed in alphabetical order.

So, the next time you
take a walk, think about
what is going on far, far
below your feet.

Below the crust it is so hot
that rocks melt. This melted
rock, called magma, moves
up toward the crust. If there
is a crack in the crust, the
magma rises through the
crack, like smoke through a
chimney. Then the magma
flows out onto the surface
as red, glowing lava. Huge
areas may be buried. That’s
a volcano.

The top layer of Earth, its
crust, is composed of large
pieces called plates. When
two of these plates bump, the
force can break rocks. When
that occurs, the ground
trembles and shakes. That’s
an earthquake.

We think of Earth as rock
solid. Rock, maybe; solid, not
exactly. Far beneath our feet,
powerful forces are always
at work. Earthquakes shake
the ground. Volcanoes erupt
sending fireworks into the
sky. Why?

Look at this volcano. Write about what you see. Use words that will help others “see” what you see. Use words from the Words
to Know list.

	Access Content Use ELL Poster 15 to preteach vocabulary. Choose from the following to meet language proficiency levels. Beginning Point out that words in a dictionary are listed in alphabetical order. Show students how to find words in a dictionary by looking letter by letter in the unfamiliar word. Intermediate After reading, students can use a Venn diagram to sort words that refer only to volcanoes, those that do not, and those that do both. Advanced Teach the lesson on pp. 382–383. Students report on the names of these different geological events in their home languages. Resources for home-language words may include parents, bilingual staff members, bilingual dictionaries, or online translation sources. Dictionary Have students work in pairs to follow the steps on p. 382. Encourage them to list the guide words at the top of the dictionary pages on which they found the meaning of each vocabulary word.
