for Dinosaurs

SUMMARY This book explores the careers and

impact of various important paleontologists

It also explains animatronics, the technology

used to build robotic models of dinosaurs

LESSON VOCABULARY

erected foundation mold

occasion proportion tidied

workshop

INTRODUCE THE BOOK

INTRODUCE THE TITLE AND AUTHOR Discuss with

students the title and author of Searching for

Dinosaurs Ask students to try to identify the

image in the photo (fossil) Ask students to tell

of any other books they’ve read on dinosaurs

Do they think this book will be fiction or

nonfiction? Why? (nonfiction; the label on the

cover says Earth Science)

BUILD BACKGROUND If needed, define

paleontologist (See page 6.) Have students

share any knowledge of paleontology or

experience looking for fossils Also explore

knowledge and interest in robotics Ask if

anyone has seen robotic models of dinosaurs

PREVIEW/USE TEXT FEATURES As students

look through the book, draw their attention

to the map on page 9 Have them point out

the key and the symbol used to represent

dinosaur finds Then have students use the

illustrations and headings in the book to

predict what the book will be about

READ THE BOOK SET PURPOSE Have students set purposes for

reading Searching for Dinosaurs Students’

own interest in fossils, dinosaurs, and robotics should help guide their purposes Students may want to know where different fossils are found and how they serve as models for making robotic versions of dinosaurs

STRATEGY SUPPORT: PREDICT Discuss that it

is important to keep revising, or changing predictions, based on new information Before students read the section on animatronics, have them preview the section headings and pictures What do they think they will learn about how animatronics are made? Have students write down their answers Then, after they read pages 16–17, they should revisit their prediction and rewrite it using new knowledge they have gained from the text Finally, after completing the section showing all the steps in animatronics, they should go back and read their last prediction, noting what part of it was correct Afterwards, discuss the predictions and revisions as a group

COMPREHENSION QUESTIONS

PAGE 4 Why is Sue such a famous fossil? (It is

the largest and most complete Tyrannosaurus rex fossil ever found.)

PAGE 13 What word in the heading makes this

statement an opinion? (amazing)

PAGE 14 How was Joan Wiffen’s educational background different from that of many other

modern fossil hunters? (She did not have a

degree in paleontology.)

PAGES 18–21 How do the pictures on these pages help you predict what you will learn

about animatronics? (Answers will vary.)

READER RESPONSE

1 Possible response: Facts: In 1995 Sereno

and Lynn led a fossil-hunting team to

Africa In 1997 David Varricchio

spotted a fossil claw sticking out of the

desert sand Opinions: The trip’s highlight

occurred when Sereno discovered a fossil

skull It was a great find, but even more

lay in store

2 Answers will vary.

3 It is important because everything else

rests on, depends on, or is built on it

4 Answers will vary.

EXTEND UNDERSTANDING Direct students to the

chart on page 18 Elicit that it is a summary

of the steps involved in making animatronics

Discuss whether or not having the chart to

refer to helped students understand and

organize the steps better

To check students’ understanding, have them retell sections of the text in their

own words Allow them to point to illustrations

to help with the retelling

RESPONSE OPTIONS

WRITING Invite students to choose one of

the fossil hunters in this book and write that

person a letter What would students like to

say to him or her? What would they ask?

SCIENCE CONNECTION

Have students further

research dinosaurs and

dinosaur fossils Then invite

them to use modeling clay to

recreate a chosen dinosaur or dinosaur

fossil Have students label and display their

creations

TEACH/REVIEW VOCABULARY

Many of the words have multiple meanings

To clarify the usage of these and other vocabulary words, discuss the contextual

meanings: occasion, page 14; mold, page 18; foundation, page 19; proportion, page 19; tidied, page 20; workshop, page 23; erected, page 23.

TARGET SKILL AND STRATEGY

FACT AND OPINION Remind students that

a statement of fact can be proved true or false A statement of opinion is someone’s

judgment, belief, or way of thinking Read the last sentence on page 6 Ask: Can

this statement be proved? (No; the words greatly and respected make it an opinion.)

Then read the first sentence on the page and have students tell if it is a statement

of fact or opinion (fact) Tell students that

as they read, they should ask themselves if the information they are learning is fact or opinion

PREDICT Remind students that to predict

means to tell what you think might happen next in a book, article, or story based

on what has already happened and prior knowledge of the subject Tell students to

note that in Searching for Dinosaurs, the

author uses a mix of fact and opinion As students read, they should bear this style

in mind to help them predict what facts they will learn about fossil hunters and their discoveries

ADDITIONAL SKILL INSTRUCTION

COMPARE AND CONTRAST Remind students

that to compare is to identify how two

or more things are alike, and to contrast

is to identify how they are different To help students understand the differences between computer special effects and animatronics, have them construct a Venn diagram As students read, suggest they jot down some notes comparing the two processes

Fact and Opinion

• A statement of fact is one that can be proved true or false.

• A statement of opinion is a statement of someone’s judgment, belief, or way of thinking.

Directions Read each sentence below Write whether the sentence is a statement of fact or of opinion.

1. Probably the best explanation for why people become fossil

hunters is curiosity

2 Today, the field of dinosaur paleontology is thriving, thanks

to the efforts of many world-renowned scientists

3 Since the early 1800s, scientists on several different continents

have discovered more than 300 dinosaur species

4 Paul Sereno worked hard in college and graduate school to make

his dream of becoming a dinosaur paleontologist a reality

that it ate like a crocodile

6 Joan Wiffen worked hard to overcome the scientists’ lack of faith

in her abilities as a paleontologist

7 A full-sized model can be made by hand or through

such modern manufacturing techniques as CAM (Computer-Assisted Manufacturing)

8 The artists and engineers have done their best to create the

best possible model for the museumgoer or moviegoer

to see, hear, and enjoy

Directions Write one statement of fact about dinosaurs Then write one statement of opinion.
