  1. Branches of Earth Science Section 1 Page 6

  2. Daily Science Question: • Imagine that you are an Earth scientist and can travel wherever you want to on Earth. Describe the aspects or features of Earth that you would like to study.Explain where you would go and what you would do. • Make sure you answer all questions above in five sentences or more. If you finish early, illustrate your answer as well.

  3. What do you think? • Geology • Oceanography • Meteorology • Astronomy LOOK IT UP!!! Researcher: look it up, Writer: write it down, Presenter: tell us what you found. You have 10 minutes… Use a dictionary to look up each prefix.

  4. Put it all together…

  5. Ch.1 S.1

  6. 2. Which of the following Earth scientists would study tornadoes? c. A meteorologist

  7. 3. On which major branch of Earth science does geochemistry rely? a. geology

  8. 4. List the major branches of Earth science. The major branches of Earth science are geology, oceanography, meteorology, and astronomy.

  9. 5. In which major branch of Earth science would a scientist study black smokers? oceanography

  10. 6. List two branches of Earth science that rely heavily on other areas of science. Explain how the branches rely on the other areas of science.

  11. 7. List and describe three Earth science careers.

  12. Homework: • Record vocabulary words from section one on a piece of notebook paper. We will glue this in your composition book tomorrow.

  13. Daily Science Question: • How can paleontologists know what a dinosaur looked like, how it behaved, and what it ate by studying fossils? • Remember to answer all parts of the question in 5 sentences or more.

  14. Ch.1 S.2

  15. 2. Which of the following is NOT part of scientific methods? d: close the case

  16. 3. Which of the following is the stem in scientific methods in which a scientist uses a controlled experiment? • B: test the hypothesis

  17. 4. Explain how scientists use more than imagination to form answers about the natural world. • Scientists perform controlled experiments and make observations to study the natural world.

  18. 5.Why do scientists communicate the results of their investigations? • Scientists communicate the results of their investigations because scientific progress depends on the exchange of information.

  19. 6. For what reason might a scientist change his or her hypothesis after it has already been accepted? • A scientist could change his or her hypothesis because subsequent observations or experiments provide new data.

  20. Ch.1 S.3

  21. 2. Which of the following types of models are systems of ideas? • C: conceptual models

  22. 3. Why do scientists use models? • Scientists use models to study objects, systems, and concepts. They also use models to communicate results.

  23. 4. Describe 3 types of models. • Physical models are models that you can touch. • Mathematical models are made of data and equations. • Conceptual models comprise ideas and hypotheses supported by observation and data.

  24. 5. Which type of model would you use to study objects that are too small to be seen? Explain. • All three types of models could be used to study objects that are too small to be seen.

  25. 6. Describe why the climate model is a mathematical model. • A climate model is a mathematical model that comprises a vast amount of data. Equations help predict the consequences of changes in the data.

  26. Environmental science Meteorology Geochemistry Astronomy Oceanography Physical Model Conceptual model Scientific methods Volume Temperature Density Physical geography Paleontologist Seismologist Geology Model Mathematical model Theory Meter Mass Area variable Chapter 1 Study GuideTerms to know:

  27. Short Answer: • Describe the 4 major branches of Earth Science. • Describe the 4 areas of oceanography. • Describe the steps of the scientific method. • Interpret a mathematical graph. • Explain the advantages of using SI units.
