In a few examples in class, we talked about the market for low-wage labor. We assumed that the demand for low-wage labor (by employers) is relatively inelastic, and that the supply of low-wage labor (by the workers) is relatively elastic. Choose ONE of these assumptions, and explain in your own words why it is likely true. Make sure that your explanation illustrates your understanding of what elasticity means (that’s what I’ll be looking for).

For this question, please write two paragraphs. In the first paragraph, describe some of the bad things about cities. In the second paragraph, cite at least 3 pieces of evidence to help explain why, in spite of these things, Dr. Glaeser titled his book The Triumph of the City.

Compose a potential thesis statement for your essay.  The thesis must include your topic, your central point, and three map points.  Using the teacher example, a possible thesis is “My 7th grade science teacher is my favorite teacher because she is caring, creative, and upbeat.”

The term ________, also called the looking-glass self, refers to our perception of another’s view of us.

Foliation is even evident on the microscopic scale. The following images are photomicrographs made by looking at thin slices of rock under a microscope. The individual grains of the rock are visible. Looking at the alignment of the minerals, can you determine which of the pictures properly shows the direction of compression leading to the development of this metamorphic texture?

Let’s look at a simple cross section. Here we see where a dike has intruded into some sediments. Using the principles of relative dating, label the five rock units from the oldest (1) to the youngest (5). If this is completely new to you, check out this interactive animation for a full explanation. RELATIVE AGE DATING

So, sea level is rising…What does that mean for our future? From computer models, scientists have produced the following graph to help us visualize expected amounts of sea-level change. Based on the graph, categorize the following estimations as to whether they are too high, too low, or within predicted rates of sea-level rise.

Some metamorphic rocks are not foliated because of mineral growth or recrystallization without a preferred orientation. Below are the names of several metamorphic rocks. Identify whether each rock has foliation by dragging each name to the correct box.

  There is a hole in the ozone layer? Great. What can possibly be done? This final video shows reason to be optimistic, not just about the ozone layer, but about humanity’s ability to act. The following video shows the location and intensity of the ozone hole from 1979 to 2013. Take note of the line graph, included below, that shows the minimum concentration for each year. Click here to open the video with closed captions in a new window. Since 1993, what has the trend been for minimum ozone concentrations at the South Pole?
