Where, specifically, is the “Great Pacific Garbage Patch” (GPGP) located? What are the names of the two areas (be specific) that contain the highest concentration of plastic in the GPGP? How was the Pacific garbage patch found, when was it found, and who discovered it? (4 points) 2. What is a gyre? Describe in detail how gyres lead to increased accumulation of plastic pollution and floating trash. (3 points) 3. According to the 2-minute “Ocean Today” video, how many gyres are there in the world? How large (in square miles) is the North Pacific Subtropical Gyre? What are the names of the four ocean currents that make up this gyre? (4 points) 4. Identify four different examples of plastic trash found in the GPGP. Why is plastic the most common type of trash found in the gyre? (3 points) 5. Define the terms biodegradable, and photodegradable. Which of these two terms correctly describes plastic? How large (or small) are most of the plastic pieces in the GPGP? (4 points) 6. Imagine you are aboard Charles Moore’s catamaran boat, sailing through the GPGP. How would you describe what you see? What does the water look like? Are there large pieces of plastic trash covering the ocean surface, or are the individual pieces harder to see? (4 points) 7. Describe the two different sources that account for the trash found in the Pacific Garbage Patch. What percentage of the pollution comes from land, and how does it get from land into the ocean? What percentage of the trash comes from sea activities? What are the sea activities that cause this pollution? (4 points) 8. Explain in detail two different ways in which plastic pollution can cause harm to marine organisms and birds. How does plastic in the GPGP allow chemicals like DDT and PCB’s to work their way into the food chain? (4 points) 9. In his 7-minute TED talk, Charles Moore questions and criticizes plastic recycling. Based on what he says in this video, why is Charles Moore critical of plastic recycling? What does he think is the best and most effective strategy to reduce the amount of plastic waste that ends up in the GPGP? Support your answer with specific examples from the video. (5 points) 10. What is meant by Jeffrey Ernst’s quote that the patch is “just a reminder that there’s nowhere that isn’t affected by humanity”? Do you think it is possible to clean up all of the plastic in the GPGP? Why or why not? Explain your answer in detail. What do YOU think is the best solution to solve the problem of plastic pollution in the GPGP? (5 points) Your responses to the following eight questions are due on Tuesday, April 5. Be sure to have your written or typed responses ready to show me at the beginning of class on Tuesday.

Surveys for all class sections have been emailed to you. Check your inbox. Make sure to complete by Sunday evening, no later than 7 PM. Have a great weekend, and thank you all for your hard work and good ideas for the recycling project this week! For Monday, please complete the following two assignments:
The results from the grade-wide recycling survey are shown below. In preparation for class tomorrow, please look at this data, and be prepared to discuss the following questions:
For tomorrow, please write a two paragraph response, with the heading "Everyday Materials and Recycling," that addresses the following:
Remember that the everyday materials we are talking about are:
For homework tonight, please read the article entitled "Killer Clothes" in the new Science World issue that was handed out in class today. The article begins on page 8.
You can also access the article (and the entire issue) online using this link: http://scienceworld.scholastic.com/ From this page, simply click on sign in and then select student in the next window. The password to login to our school account is tw704. This article will serve as an introduction to our next unit: materials chemistry and materials engineering. In particular, the article looks at an unfortunate but common byproduct of engineering and producing different materials: pollution. The intersection between materials engineering and pollution will be a theme we explore throughout this unit. Please be prepared to discuss the article in class tomorrow. This is a make-up assignment only for students who have not yet handed in the Science World/technology writing response assignment.
For this assignment, first select one copy of any one of the old issues of Science World magazine, found on top of the back shelves in my classroom. After selecting an issue, read through the magazine and find any article related to electricity, power generation, or batteries. After choosing this article, write a four paragraph summary about the article in the following format: Paragraph 1: summary of the article and how it relates to electricity Paragraph 2: concepts of electricity (such as voltage, current, power, resistance, conductors, electrons) that we have recently learned in class that are discussed in the article or that relate to the article Paragraph 3: explanation of what you learned from this article that you now understand based on your knowledge of electricity but wouldn't have understood previously. Paragraph 4: conclusion of your thoughts and any questions that you have based on the article.
Check out these cool links below, based on the foss spring boards we used in the lab today. The first link lets you play with an interactive version of the boards we used in the lab, and the second link lets you see wiring diagrams for different kind of circuits. Great practice to help you in the lab!
Please complete questions 1-10 from the Ohm's Law and Power Practice Problems worksheet. This sheet can be viewed and downloaded from the resources section of my site. The notes taken in class today should be used to help you complete these practice problems. The equations for Ohm's Law, power, and electricity can also be found on the back of your homework sheet.
For tonight's homework, please carefully read pages 141-142 and 144-145 from your Engineering Fundamentals textbook. 141-142 deals with Ohm's law and covers voltage, resistance, and current. 144-145 describes parallel and series circuits. Please make sure you are familiar with both of these topics for tomorrow's lesson.
For tomorrow please be sure to complete the following reading and workbook pages:
Below is "Extra Credit #4," which is due by Friday, January 8 at the latest. To receive full credit:
We need 2-3 empty soda cans per class (20 total) for part of our "Gas Laws" lab tomorrow -- so anyone who has an extra empty soda can or two lying around your house, please bring them in! Please rinse the cans out with water before bringing them in, and make sure that they are not dented in at all. Thanks!!
