6 MONARCH PARK COLLEGIATE 6 PART B: INQUIRY AND COMMUNICATION (36 MARKS) INVESTIGATION: ACCELERATION DUE TO GRAVITY DESIGN: You will use a mouse ball, 2 metre sticks to make a ramp, a stopwatch and a Science 10 textbook. Allow the mouse ball to roll down the ramp for different distances (maximum 100 cm). The amount of time it takes the mouse ball to roll the different distances is given to you (see the following data). A velocity - time graph to determine the acceleration of the mouse ball will be drawn. Data: The mouse ball is at rest at 0 seconds. It takes an average time of 1.0, 1.4, 1.7, 2.0, 2.2, 2.4, 2.6, 2.8, 3.0, and 3.15 seconds to roll 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100 centimetres. QUESTIONS: a) What is the question (problem) to be investigated? (1 mark) b) Using the above information and the data provided, write a detailed procedure (in numbered steps) that you will follow to carry out this investigation. (10 marks)

7 MONARCH PARK COLLEGIATE 7 c) Prepare a labeled table for the above data ( Be sure to show all mathematcial formulas). (10 marks) d) Draw the velocity - time graph using the above data on the graph paper provided. (10 marks) e) Using your graph calculate the mouse ball's acceleration at the 70 cm mark. Show all work, on your graph, for full marks. (5 marks). PART C: MAKING CONNECTIONS ( 10 marks) Instructions: a. Answer any one of the following questions in the space provide on the answer sheet. b. Full marks will be awarded for answers that are clear, concise, and accurate. c. Answer in full sentences. Marks will be deducted (maximum 2) for spelling mistakes and grammatical errors. d. Your answer must show that you have researched the topic thoroughly. e. Your answer is worth 6% of the final year end mark. Answer any one of the following: 1. Scientists have evidence that the depletion of the ozone layer is caused by chlorofluorocarbons (CFCs) that have been released through human activities into the atmosphere. Research this issue and answer the following questions. a) What are CFCs and what are their sources? b) How are CFCs believed to speed up the destruction of the ozone layer? c) What alternatives are now used to replace these chemicals? 2. Choose a university and college that you would like to attend. In tabular form; a) List environment-related programs offered at the schools. b) Identify the program that most interests you. c) Note the program in which a strong background in chemistry would be useful or is required. 3. Aquaculture (fish farming) has been suggested as an alternative to taking wild fish from the oceans. It has been claimed that the more use of aquaculture will increase the amount of food for humans while reducing pressure on natural marine ecosystems. Research aquaculture and indicate some benefits and limitations of this technology in solving the problem of over fishing Write your answer on the following page
