Modelaskingquestionswhilelookingatthetableofcontents.Think-aloud:When Id like to know more than I do about a topic,I can use the section titles in the table of contents to think of questions Id like to have answered.For example,the second section is titled“Deep Within the Earth.”This makes me wonder what is below Earths surface.(Write thisquestionintheW section of the KWL chart and invite

Comprehension Skill:Fact or opinion Revieworexplainthatafact is something that has actually happened and can be proven to be true.Anopinion is a belief,based on a personal feeling,which cannot be proven.Tell students that it is important for readers to be able to distinguish fact from opinion in order to make a sound judgment about the information they read and hear.Talk about the many different scientific facts that the book might contain and the feelings that the photos and descriptions may elicit.Havestudentsturntopage15,lookatthephotograph,andreadthecaption.Think-aloud:When I read the caption under the photograph,I found out that scientists gather information about volcanic eruptions.I know that the information they discover will be based on various tests and will therefore be able to be proven as truth by these tests.As I look at the photograph,I wonder about the people who live near the volcano.I wonder if these people were there when the volcano erupted.I wonder if these people have lived through this type of experience before.I wonder if they were scared or excited.I know that whatever each person felt,each one has his or her own opinion about the volcanic eruption.As a reader,it is important for me to know the difference between the facts of a situation and the opinions of the same situation.Introduce the Vocabulary Asstudentspreviewthebook,pointoutanycontentwordsthatyouthinkmaybedifficultforthem.Remindstudentsofthestrategiestheycanusetoworkoutwordstheydontknow.Forexample,they can use what they know about letter
