Hello, Class,
This exercise will continue building on the research skills that you started last week in becoming familiar with academic research and the UMUC library databases. To continue expanding your perspective on your selected technological transformation theme, you will want to locate additional sources that agree or disagree with the first article that you’ve chosen. Please note: the articles that you have already started to locate
can
be used in Writing Assignment #2 (Descriptive Annotated Bibliography).
Assignment
(1) Please continue to study the video tutorials. Here are the links for quick access:
Video tutorial #1
http://polaris.umuc.edu/de/csi/2012_library_tutorials/tutorial_01/tutorial_01.html
Video tutorial #2
http://polaris.umuc.edu/de/csi/2012_library_tutorials/tutorial_02/tutorial_02.html
Video tutorial #3
http://polaris.umuc.edu/de/csi/2012_library_tutorials/tutorial_03/tutorial_03.html
(2) After watching the tutorials, please find
another
article about your chosen technological transformation theme. You can search for articles that respond directly to the textbook articles, if you’d like. In addition, you might consider finding articles that disagree with the textbook articles. When you have found your additional article, please write a short summary (7 to 12 sentences) of that article and post it below. Also, please provide two of your classmates with generous responses to their summaries.
The second week of class covers ancient societies and civilizations in Africa and South Asia. Because of my error, I have included some questions from last week’s conference, some of which I have rewritten. If you answered one of the questions last week, please do not answer the same one this week. My apologies to all of you for this mistake.
Please answer at least ONE of the following questions. Remember to answer as completely as possible, and explain using specific facts, events, and other points. Organize the answers and produce well-written efforts. Work to develop the answer beyond basic facts by explaining points fully. Work to post your main answer by Thursday to help your colleagues and to avoid the Sunday rush.
As a short cut, you may cite the text as “Bentley and Ziegler, 108” (noting authors and page numbers). Other sources should be cited fully using the University of Chicago Style (Turabian). When in doubt, cite and reference completely.
1. Discuss human societies and states in Africa. What develops and where? How do human migrations affect the regions of Africa? Who is involved and what results from these movements?
2. How does Egyptian civilization develop? How does it differ from Mesopotamian? How is it similar? Explain. How does it change over time and why? Explain Egyptian religion and compare it to other societies’ beliefs.
3. Why is it said that Egyptian society is conservative? Do you agree or disagree? Why? Explain. Does the longevity of Egyptian society influence this outlook? Compare Egyptian stability with those Mesopotamian states we studied last week.
4. Who were the Bantu and what are the Bantu migrations? Explain, providing specifics as to location, dates, and the impact of these movements of people.
5. Compare the Egyptian-Nubian and Bantu-sub-Saharan societies. What is similar about them? What is different? In agriculture? Technology? Religion? Explain.
6. When and how does the Indus River Valley or Harrapan civilization develop? What specifics of its development are similar from the previous river civilizations we studied (Egypt and Mesopotamia)? How is Harrapan society different? Explain, providing examples.
7. Why is Indo-European migration important for the development of Indian civilization after 1500 B.C. (BCE)? Who are the Aryans? How do the Aryans influence this Indian civilization? Who are the Dravidians? How does their society change with these migrations? Discuss.
8. How does Indian society develop as a result of the movement of peoples? Discuss politics, religion, and society. How does this South Asian civilization compare with others we have studied? Discuss some differences. What similarities exist? Explain, using examples.
9. After answering one of the questions above, are there any other issues or questions you would like to your colleagues to consider. Please post here and discuss.

The goal of this experiment is to create a recipe for the best tasting vinaigrette salad dressing, using only four ingredients: red wine vinegar, vegetable oil, salt, and pepper. Everyone will start with the same basic recipe, then each of you will make your own modifications. You must keep a record of everything that you did to create your salad dressing, including any changes that you made to the recipe along the way. You will be sharing your final recipe with the class so that others can reproduce it and vote on the best tasting salad dressing.
Start with the following basic recipe:
· 3 tablespoons (T) of vinegar
· 3 tablespoons (T) of oil
·
1/4 t
easpoon (t) of salt
·
1/8 t
easpoon (t) of pepper
Mixing Instructions: Place all ingredients in a bowl in random order and mix all ingredients together at the same time.
Taste your mixture. Then, if you decide more or less of any of the ingredients is needed, make a new batch based on your adjustments, taste the resulting dressing, and record your results. Your adjusted measurements must be at least reasonably measurable (for example, “a pinch” or “a hint” of an ingredient cannot truly be measured). You may make as many adjustments as you choose, until you obtain a vinaigrette salad dressing that you feel is the best tasting. Just be sure to record each adjustment.
Your instructor will have you post your final recipe in a conference a few days before the final lab report is due. At that time, you should print out the other recipes and test each student’s recipe. Your instructor will let you know how many of your classmates’ recipes you should test. Then, by the due date listed in the syllabus, you should submit the following report:
1. Submit your record of what you did to create your final recipe. Start with the first recipe and make sure to include all changes that occurred as well as your evaluations of the results of each recipe. For example, you should state how each of your recipes tasted, and why you decided to continue adjusting the recipe (as appropriate). Be sure to include how you mixed the ingredients and in what order. Record your final results in the chart below. If you make fewer than 4 recipes, ignore the remaining recipe columns. If you make more than 4 recipes, use the second set of recipe columns.

3. How did your best recipe taste?
4. Which student’s salad dressing recipe tastes the best? (You may choose your own.)
5. Explain why this recipe tasted best. Include in your analysis comparisons to other recipes and why you felt they did not taste as good as the chosen recipe.
6. State a hypothesis for this experiment.
7. What was the control in this experiment? Explain your answer fully.
8. How did you test your hypothesis?
9. Did you prove or disprove your hypothesis? How did you decide whether it was proven or not? Explain fully.
10. What is the importance of keeping a complete record of what you did in preparing your recipe?

Assume that your yard has many tall trees that result in about fifty percent of the yard being shaded and fifty percent of the yard being exposed to full sun. The shaded areas and full-sun areas are all intermixed. You are reseeding your lawn and wish to buy only one type of grass seed. The label on Seed 1 states that the grass is excellent in full sun and good in shade, and the label on Seed 2 states that the grass is excellent in shade and good in full sun.
Using the scientific method, design an experiment to determine which seed is best for your lawn. Make sure to account for all steps of the method and to identify your controls.
