What do environmental scientists study? ______________________________________________________________________________ ______________________________________________________________________________ 2. “Environment is often used to mean the nonhuman or ‘natural’ world.” Why is this incorrect? How are humans a part of nature? __________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 3. Will the ozone hole ever be gone? Why or why not? _________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 4. Study the environment is very complex. What are the different disciplines that contribute to environmental science? __________________________________________________________ _____________________________________________________________________________ 5. One reason environmental scientists are different from environmentalists is that scientists try to maintain an unbiased approach to their research. What is ‘bias’? THINK: Why is bias detrimental to the scientific process? ________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 6. On our island Earth, what is the problem with the human population increasing drastically? ______________________________________________________________________________ ______________________________________________________________________________ 7. Outline the “Renewability Continuum” below. Give examples at each step in the continuum. 8. How many people do we add to the planet each year? ________________________________ 9. Based on the history of the United States, what is the reason for the increase in our absolute population number? _____________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 10. What are the 2 components that the ecological footprint expresses? ____________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 11. What other organisms have an ecological footprint? _________________________________ ______________________________________________________________________________ 12. The average American has an ecological footprint of _______________________. Do you think your footprint is below, the same, or higher than this average? _______________________ 13. What is meant by tragedy of the commons?________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ Lesson 2: The Nature of Science Guiding Question: What does it mean to “do science”? Vocabulary: Know the definition of each term. Hypothesis- Prediction- Independent variable- Dependent variable- Controlled study- Data- Guided Reading: 1. What is science? ______________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 2. “Science assumes that the natural world functions in accordance with rules that do not change unpredictable from time to time or from place to place…Scientists examine the workings of the natural world by collecting evidence.” However, why can nothing ever be proven? ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 3. The process of science involves certain logical steps. Real science usually involves loops of the steps on the way to reaching a conclusion. Reading carefully, (without the loops) what are the general steps, in order, of the scientific method? ______________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 4. Using the example the authors use in the textbook, what is an independent variable vs. a dependent variable? _____________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 5. What is a controlled variable? What does it mean for variable to show correlation? _________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ 6. What can data do for you as a scientist? ______________________________________________________________________________ ______________________________________________________________________________ 7. Summarize the information shared about the ozone layer and hole within this chapter. ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ ______________________________________________________________________________ Lesson 3: The Community of Science Guiding Question: What happens to a scientific study after data have been gathered and the results are analyzed?
