Batteries Group Discussion Questions

 Use these questions to guide your data summary.  Please do not just  answer the questions numerically 

1. What is a lead-acid battery and how does it work?

2. What are the most widely used types of batteries for solar and/or backup systems?

3. What is the difference between connecting in parallel and series strings of wiring?

4. How does depth of discharge influence the capacity of the needed battery bank?

5. How does weather influence the capacity of the needed battery bank?

6. How does the location of battery storage (e.g., temperature controlled or outside) influence the capacity of the needed battery bank?

7. Discuss some practical ways you can reduce the capacity of the needed battery bank if you were living in an off-the-grid scenarios.  Remember you entered the Watt hours needed based on your current energy usage.

For Professor Avril

Discussion 1

Calculate your personal ecological footprint using Global Footprint Network’s Footprint Calculator and briefly summarize your results. Were you surprised by any aspect of your ecological footprint?

Discussion 2

  • Select a pressing environmental issue that has personal relevance. You may find ideas from the textbook, from mainstream media, or from the list provided. Once you choose a large-scale issue, think about how the issue impacts you personally. For example, you may be interested in water quality (the larger issue). You could then consider how water quality impacts you in your daily activities such as drinking water that is contaminated with pharmaceuticals or agricultural waste (personal impact).

 

  • Compose a brief (1- to 2-paragraph) introduction to your topic by stating why it is a pressing issue. Be sure to support your statements with facts and details from credible sources.

 

  • State how the issue impacts you personally (1 paragraph) and include a summary of at least one local or regional problem associated with this issue (1 paragraph).

Discussion 3

 

Then, search Science Daily or a news story about a natural science topic that’s less than six months old. Make sure to choose a story that interests you, because you’ll use this news story for all the projects in this course.

Once you’ve chosen a news story, summarize the main ideas from the article. Then, draft two questions that a natural scientist might ask about the topic. Include both the summary and the two questions in your initial post. As you write your questions, think about what you’ve learned about the natural sciences and scientific thinking in the module overview. For instance, if you chose an article on volcanic eruptions, you might ask: what causes eruptions to happen and how do we predict when they’ll occur? Make sure to include the news story title and a link to it in your post.

Dividing The World

/in /by

“What is the essential dividing line between human beings around the world?”

In your opinion, is there one fundamental difference which separates people of the world?
What is the primary division of the world?
As global citizens vs citizens of somewhere?
As the winners and losers from globalization?
As a clash of civilizations?

There is no necessarily correct answer for this assignment – points will be given for clear expression of thought.
An equally valid response is to explain why you think there isn’t one fundamental way in which the world separates.

Assignment instructions:

Part 1
Read the three articles:
1 – Friedman – It’s a flat world, after all
2 – Forsyth – Theresa May’s new 3rd way
3 – Gelfand – Here’s the science…

Part 2
Summarize and explain the key global division identified in each article. This should be at least a paragraph per article.

Part 3
Which of the three approaches do you find most convincing for explaining the world? Give justification for your answer. If you prefer a different framework for identifying the world (e.g. Huntingdon’s Clash of Civilization thesis), this is the point to introduce it. To have a chance of maximum points, you should try and explore how the three readings connect with each other, even though they use different frameworks. For example, are the winners and losers for Friedman the same groups as Gelfand identifies?

Part 4
Depending on your answer to Part 3 – which single policy would you advocate for to improve the quality of life of those identified as losing out from globalization.

Briefly summarize the primary health effects associated with overexposure to each type of metal fume, including both acute and chronic health effects. Explain what analytical methods you would use for evaluating health hazards in the workplace.

Identify the types of metal fumes that would produce similar health effects on an exposed worker. Assume that each listed metal can cause respiratory irritation. Use the equation in 1910.1000(d)(2)(i) to calculate the equivalent exposure (in relation to OSHA PELS) for the metal fumes with similar health effects based on the “Result” column in the table above. Discuss whether you believe any of the individual metal fume exposures or the combined exposure exceeds an OSHA PEL or an ACGIH TLV.

Your homework assignment should be a minimum of two pages in length.

(1) Given the typical water usage in the U.S. is approximately, 180 gallons per capita day; Estimate the population served by the James W. Jardine Water Purification Plant, Chicago, IL.

 

(2) During wastewater secondary treatment processes, air is added to the wastewater. Why is this step necessary?

 

(3) In dry seasons, the majority (~85%) of water in some rivers is the direct result of wastewater discharges and it is common practice for drinking water plants to treat this waster for potable supply. It is being suggested that we should skip the step of discharging wastewater into rivers and directly pump the wastewater to the drinking water plant for treatment. Would you be willing to use this water in your home as drinking water? Do you think this is a good idea (state why or why not)?

Please write an essay of about 1,000 words, answering ONE of the following questions. Please attempt to use evidence from the attached readings, using recomended readings to increase your score and cite your own sources. Use historical examples, not ones from our own times.

a) Compare and contrast three regions outside the United States in which Americans have contributed to large-scale ecological transformations. In your view, who or what bears the primary responsibility for these transformations? Develop an argument and persuade me.

b) A newspaper editorial once stated “Few should weep over the buffalo” because American power rested on its ability to exploit natural resources. Other than the buffalo, identify three “natural resources” whose exploitation as commodities radically altered the environment within the United States. What were the principal causes and consequences of this exploitation? Develop an argument, and persuade me.
