Lesson 3
Case Study
Skim Lesson 3 in your book. Read the headings and look at the photos and illustrations. Identify three things you want to learn more about as you read the lesson. Record your ideas in your Science Journal.
Differentiate types of variables.

Prediction
Sequence the error analysis regarding possible pollen contamination of Dr. Oeggl’s lab. Pollen was found in Iceman’s digestive tract sample. Suspicion: Test of control group:

Connect an inference to a revised conclusion. Inference The Iceman’s digestive contents indicate that he died in spring.
Revised Conclusion
Synthesize It
Describe how an early hypothesis in the scientific investigation of the Iceman was not supported by evidence.

Chapter Wrap-Up Now that you have read the chapter, think about what you have learned.
Use this checklist to help you study. Complete your Foldables® Chapter Project. Study your Science Notebook on this chapter. Study the definitions of vocabulary words. Reread the chapter, and review the charts, graphs, and illustrations. Review the Understanding Key Concepts at the end of each lesson. Look over the Chapter Review at the end of the chapter.
Summarize It
Reread the chapter Big Idea and the lesson Key Concepts. Summarize how the case study described in Lesson 3 demonstrates the Key Concepts in Lessons 1 and 2.

Challenge Choose another ongoing scientific investigation to learn about. Research to learn about the questions that scientists are trying to answer. Write a news program-style script about that reallife scientific investigation. Perform your “news broadcast” for your class. (Be sure to differentiate between facts and opinions in your story!)
