Read
To introduce the selection, read aloud the title. Invite students to
generate a list of questions that they think will be addressed in the
selection. Organize their ideas in a class chart using the following
words to sort the types of questions: Who? What?
Where? When? Why? How?
Activate students’ prior knowledge by asking the following questions:
- “Where
are satellites located?”
- “How
do satellites work?”
- “Why
do you think scientists use satellites to track caribou?”
- “What
other technology helps scientists collect data about wildlife?”
- “What
kinds of information are collected?”
Use the Clue Collector strategy to
focus students’ attention on the upcoming reading selection:
Write the following verbs on a handout: send, orbit, scan, locate,
register, programmed, transmit, costs, captured, swim, armed, drawn,
propel, tied and kick. Ask students to predict how these words
could be used by an author writing an article about satellites
and caribou. Elicit students’ personal knowledge and experiences
as they think about the clue words. Encourage students to pair
or group clues together. Ask them to share how the clue words could
be connected or related. Invite students to write statements that
use the clues. Assist students through demonstrations and think
alouds to understand the process of looking for relationships.
Repeat this activity with nouns and noun phrases from the reading selection:
locations, blizzards, darkness, plane, earth, computers, space, signal,
power, weight, method, gun, measurements, and samples. Ask students to
work with a partner to discuss how the words might be used in the article.
Encourage students to connect the nouns with the verbs to generate ideas.
Invite students to share their predictions with the class. Encourage
them to share reasons to support their ideas.
Read the nonfiction article, “Satellites
and Caribou: The Why and How of Satellite Collaring Caribou” aloud
along with other nonfiction selections that describe satellite tracking
of migratory species.
Related Reading Selection: “Confused
about Collars? Conventional and Satellite Collars.”
Revisit
Revisit the selection to confirm and revise predictions generated prior
to reading. Highlight the verbs from the Clue Collector. Ask:
- “How
did the author use each of these verbs to reveal facts about
satellites and caribou?”
- “What
synonyms could be used in place of these verbs?”
Highlight the nouns and noun phrases in the selection. Ask students:
- “How
were these words used in the selection?”
- “How
are the words related to the topic of the article?”
Post the Pre-reading Questions:
- “Where
are satellites located?”
- “How
do satellites work?”
- “Why
do you think scientists use satellites to track caribou?”
- “What
other technology helps scientists collect data about wildlife?”
- “What
kinds of information are collected?”
Have students work in groups to reread the article and use
details from the text to answer the questions. Invite
students to research questions that were not answered by the
information in the selection.
Have each group summarize the main ideas and details of
the text by composing a condensed version of the article: Introductory
Paragraph that presents the topic, Bulleted List of key facts, Concluding
Paragraph that restates the topic.
As a class write questions that could be used as headings for each paragraph
in the selection. Discuss how these headings might help readers scan
for information, before, during, or after reading the text.
Ask students to reread the text and share sentences that helped them visualize
details as they read. Explore how authors write descriptive details
to help readers see pictures in their minds as they read. Ask students
how the photographs also helped them imagine the scenes described in
the text.
Revisit the selection to identify clue words that
signal generalization statements:
- “As a general rule, the collar’s total weight should
be no more than 4% of the caribou’s weight.”
- “Sometimes
the animals are captured while they swim across rivers during
migration.”
Ask students what conclusions can be made based on these statements.
What questions may be generated from these generalizations? For
example, how do researchers ensure that the collar is appropriate
for each caribou? What details could the author include with the
generalization statements to give readers more specific information?
Reflect
Journaling Questions:
- Why are the collars important for research?
- What are the benefits?
- What are potential costs or disadvantages?
Making Connections: The Age of Technology
- How is technology used to help people and animals?
- What are the benefits of living in a high-tech world?
- What are possible disadvantages?
Invite students to conduct a survey using
these Connection Questions. Encourage them to
interview people of different ages to get a broad sample of information
to analyze. Have them inventory the technological tools that they
use in their everyday life. Have them share predictions about how
their life would be different without the technology.
Evaluation (Examine
Author’s Strategies)
Reread the lead sentence of this article. Evaluate its effectiveness
as a lead sentence. What information did the author include to help readers
compare and contrast conventional caribou collars with those programmed
for satellite tracking?
