AP ENVIRONMENTAL SCIENCE SUMMER ASSIGNMENT 2011-2012 YOU DO NOT NEED A TEXTBOOK All the materials are also available on our school website The assignments below will introduce you to AP Environmental Science as well as give us a head start on the course, so we can complete the requisite activities prior to the AP test in May. Several of these assignments should be review for you, others will help you understand the many topics and controversies involved in the study of environmental science, while others will help you appreciate the world in which you live. None of the assignments are particularly time-consuming. We will review all of this work the first week of school, but if you have questions as you progress through the activities, you may contact me during the summer via e-mail at hbhaskar@wcboe.org ALL THE WORK SHOULD BE TYPED (SINGLE SPACE). The assignments may be done in any order, but the following is recommended, and this is how they are presented in this packet: 1.Scientific notation and Unit Conversion: Perform operations using scientific notation . You will have a quiz on this section the first week of school. 2. Outline and Answer chapters 3 questions: Read and outline chapters 3. Use a note-taking strategy that works best for you. You should have notes on the most important information in the chapter. After outlining the chapter, answer the Chapter questions. You will have a test on this chapter the second week of school. 3. Environmental Laws and treaties : Summarize the environmental laws and treaties 4. Silent Spring : Read the book and answer the questions for each section. 1. Operations in Scientific Notation done in the same power of 10. The final answer should be 3 converted to 1.165 x 10 as well. One other note about addition and subtraction: units of measure, if present, must be the same. For example, in the numbers above, if both represented a distance measurement such as meters, they could be added. However, if one was centimeters and the other meters, a common unit, say meters, must be chosen and the centimeter measurement must be converted to meters before the operation occurs. Multiplication & Division Multiplication in scientific notation is carried out in two parts. First, multiply the numbers that occur before the exponents. You need not align the decimal places. Second, add the exponents. See the example that appears below. Example #3 4 20.0 x 10 1.2 x 102 6 24.00 x 10 The final answer should appear in proper scientific 7 notation such as 2.4 x 10 . Division is the same except that exponents are subtracted. Example #4 5 20.0 x 10 1.2 x 102 3 16.7 x 10 The final answer should appear in proper scientific 4 notation such as 1.7 x 10 . Complete the problems below. Do not use calculators. Show the setup for the problem and the calculations on a separate sheet of paper.(No calculators are allowed on the AP exam). Be careful to display scientific notation as required. Also, include units in your answer! You will have quiz on scientific notations the first week of school. 3 Addition & Subtraction As with regular numbers, addition and subtraction with exponents require that decimal places be aligned. Compare the following two addition examples. Example #1 19.45 4.30 23.75 Example #2 2 1.23 x 10 10.42 x 102 2 11.65 x 10 In Example #2 above, the number 1042 was converted 3 from 1.042 x 10 in scientific notation to align the decimal places. Addition and subtraction are carried out just like addition and subtraction of regular problems, but must be 3 1. (2.3 x 10 g) + (3.5 x 10 g) = 3 2. (2.3 x 10 cm) + (3.5 x 2 2 9. (1.17 x 10 m) x (8.49 x 10 m) = 4 3. (7.88 x 10 mol) - (1.55 x 4 3 10. (4.5 x 10 m) x (1.5 x 10 2 10 mol) = m) = 5 4. (5.6 x 10 kg) - (8.91 x 2 5 11. (5.2 x 10 kg) / (1.3 x 2 10 kg) = 10 kg) = -5 5. (4.72 x 10 mg) + (4.66 x -5 4 12. (3.21 x 10 mg) / (5.3 x 4 10 mg) = 10 mg) = 3 6. (6.79 x 10 L) + (6.79 x 2 6 13. (4.34 x 10 L) x (2.01 x -3 10 L) = 10 min) = 3 7. (2.3 x 10 m) + (3.5 x 3 2 10 kg) = 3 10 cm) = 10 cm) = 4 8. (4.7 x 10 kg) x (1.1 x 4 14. (4.7 x 10 kg) x (1.1 x 2 2 2 10 m) / (2.1 x 10 s ) = - Unit Conversion In these practice problems, I am going to ask you to stick to ONLY the following conversions between the English and metric system For all problems, please show your dimensional analysis setup and give your answer to the correct significant figures.
