Include at least six to eight vocabulary words in your paragraph. 1. There have been several popular movies about dinosaurs in the last few years, including The Lost World, Jurassic Park, and Dinosaur Island. There have also been many video and computer games featuring dinosaurs. Write a paragraph describing one dinosaur movie that you have seen or one game that you have played.

Speaking 23 Partner Activity: Researching a Geological Formation With a partner, research a place with interesting geological formations or fossil remains. Many U.S. national parks and monuments, along with other geological features in the United States and the world, have many geological features. Here are a few places to get you started: Grand Canyon National Park, Arizona Badlands National Park, South Dakota Canyonlands National Park, Utah Dinosaur National Monument, Utah and Colorado Carlsbad Caverns National Park, New Mexico Arches National Park, Utah Petrified Forest National Park, Arizona the San Andreas Fault, California Mt. Fuji, Japan the Great Rift Valley, Africa Your research should focus on the geology of the area, any fossil discoveries, and any hypotheses or theories associated with the formations. Prepare with your partner a short oral presentation with visuals (photographs, illustrations, and maps) to show the class. M Role-Plays Using new vocabulary words from this chapter, act out the following role-plays. 1. You are planning a trip with a friend to the American West this summer. You want to hike down to the bottom of the Grand Canyon to see all the layers of rock exposed through erosion. However, your friend wants to go to Dinosaur National Monument to see the collections of dinosaur bones that are displayed there. Discuss the trip with your friend and try to make a decision about which place to visit. 2. You are taking a geology class this semester, and your professor has just given a lecture about the mass extinction of the dinosaurs and the various hypotheses that scientists have proposed. Afterward, you debate with a friend which hypothesis seems the most likely. You think a meteorite was the cause, but your friend thinks it was a massive volcanic eruption. Use examples to support your opinion. http://www.college.hmco.com/esl/students For more activities related to this chapter, go to the Essential Academic Vocabulary website.

READINCx CHEMISTRY FACTS: THE GOOD, THE BAD, AND THE ODD i All changes we produce consist in separating particles that are in a state of cohesion or combination, and joining those that ivere previously at a distance. John Dalton (1766-1844) Our environment is composed of atoms and molecules that undergo chemical changes to 5 produce the many substances we need and use. In producing new products, energy is released or absorbed. The following paragraphsexplain some of the infinitenumber of ways we use chemistry in our daily lives. Some of these ways are beneficial to our lives; others may be harmful or dangerous. Still other paragraphs describe chemical reactions that we may consider odd. a. Heat packs called glove warmers contain powdered iron (and other components) moistened producing the rusting of iron. This effect on the large surface area of the iron particles causes the "rusting" reaction to proceedfast enough to generate a comfortable amount of heat. b.

Write a short description of a chemistry fact that is good, bad, or odd. Describe the item, including its chemical composition, any chemical reactions associated with it, and its use in everyday life. Be sure to include any safety recommendations if the reaction is dangerous or an anecdote if it is good or odd. 8. Speaking U Partner Activity: Explaining a Chemistry Concept
It is common practice to designate the relative acidity or basicity of a solution by citing its pH (power of hydrogen) level. A pH of 7 indicates a neutral solution. Values from 6 down to 1 indicate increasing acidity, with each drop of one in value meaning a tenfold increase in acidity. Similarly, pH values from 8 up to 15 indicate increasing basicity, with each increase of one in value meaning a tenfold increase in basicity. The following diagram illustrates this concept and shows the pH values of some common solutions.
Reprinted with permission from James T. Shipman, Jerry D. Wilson, and Aaron W. Todd, An Introduction to Physical Science, 10th ed. (Boston: Houghton iMifflin, 2003), 332. Chapter 18 Chemistry
Explain the meaning of pH. Describe the range of"the chart and what the values indicate. Highlight the products indicated on the diagram, explaining what each one is used for, if necessary. Add two more products to the chart and estimate their level of acidity (for example, orange juice, tomatoes, soap, dishwashing liquid). Deduce what might happen if a person had a blood pH lower than 7 or higher than 8. How can pH level be utilized by medical practitioners? E3 Conducting an Interview Choose one of the following interview situations. Prepare for your interview by listing sixto eight specific questions to ask. Conduct the interview, take notes on the responses, and report uhe results of the interview to a partner or the class. Note: See Chapter 4 for a list of polite expressions useful in conducting interviews.
Essential Academic Vocabulary
1. You are taking a required course in chemistry this semester, and you are finding the course difficult. You face the prospect of failing the course because you just cant remember the formulas and abbreviations for the names of chemicals. Interview a student majoring in chemistry or a chemistry professor to get advice on the best ways to memorize the material and pass the course. Ask if there are any possibilities for getting chemistry tutoring. 2. Visit your campus careers center and consult a staff member about careers available for chemistry majors. Ask about the type of jobs available for people with undergraduate and graduate degrees in chemistry, the job security and prospects for professional advancement, the range of salaries in these jobs, and the personal characteristics suited to these job situations. Find out if the careers center will provide assistance for resume writing, interviewing skills, and job placement.
