Harlem Renaissance Assignment | Essay Help Services

Focus on some Harlem Renaissance Facts and then you have to solve dimensional analysis problems with those facts. And the second one focuses on doing a bit of research on the art fashion poetry etc. that were made in the Harlem renaissance and then connecting them to chemistry

This task is non-optional. You can complete it as your first or second task but to earn science credit for this project you must complete this task

Non-Optional 1 (REQUIRED):  Using your skills in dimensional analysis solve the following problems related to the Harlem Renaissance and the 1920-1930’s. We want you to keep your science skills sharp.

 Dimensional Analysis in the Harlem Renaissance

Section 1 : Complete all problems using the unit cancellation method we used and practiced during unit 1

*Challenge problem is optional

1. During the Great Migration at the “some 1 million blacks had left the South, usually traveling by train, boat or bus; a smaller number had automobiles or even horse-drawn carts.”

(History.com, 2010)

Traveling from a place like Thomasville, Georgia to Harlem, New York you would have to travel no fewer than 1,031 miles

1. How many kilometers would that be equal to? (1 conversion)

A horse-drawn cart can average about 12.5 mph (miles per hour) and can manage at the most 3 hours of travel per day

1. How many days would it take a family with a horse drawn cart to travel the 1,031 miles from Thomasville, GA to Harlem? (2 conversions)

2. Capturing the work of James A. Parsons Jr. in a sentence or two is tough. An analytical chemist in the early 1930s working for Duriron he made lasting contributions in metallurgy by developing multiple rust-resistant and non-corrosive metals. This led to the development of stainless steel

Having noncorrosive metals means that we can have appliances such as fridges and stoves that which last for years if not decades. He essentially was able to create metals that had a much much slower rate of reaction compared to pure metals such as iron or aluminum. 

A common mixture of metals (called an alloy) that makes up stainless steel is chromium, iron, and carbon.

1. Using the periodic table, what is the molar massof each of these elements:

1. In 100 grams of stainless steel approximately 11 grams would be chromium, 88 grams would be iron, and 1 gram would be carbon. Convert each of those amounts into moles.

• 11 g Cr
• 88 g Fe
• 1 g Carbon

3. One of the lesser acknowledged heroes of jazz music is banjo, an instrument with deep roots in the African diaspora. One feature of the banjo is the fourth string wrapped or made of a different material which gives it a warmer sound. This material is an alloy called Phosphor Bronze. 
4. In a sample of phosphor bronze there are 1.38 mol copper, 0.10 mol tin, and 0.03 mol phosphorus.

Convert each of those amounts into grams (total should be approx. 100 g)

~1.38 mol Cu

~0.10 mol Sb

~0.03 mol P

1. Challenge: how many moles of each element would you need to make a typical banjo string with a mass of about 3 grams (hint: for each you will need to use the mass ratios you determined in problem a)

Section 2: Please complete three of the four options below

Problem A: Not all food was available in the 1920-1930’s and people had to get creative and resourceful.

1. Look up some recipes from this time.  Here is a great place to start.

2.Look around your kitchen and find ingredients to make a least three different recipes.

3. Create a document with the recipes listed and answer the following questions.
4. Figure out how many serving of this recipe you can make using the ingredient you    have
5. Which ingredient will run out first?
6. How much of the other ingredients will be left over?
7. Using these recipes convert all the measurement into metric so it could be shared with the rest of the world.

Problem B: The “You Cannot Afford to be Gray in the Day of Youth:”, 1920s Ads slogan for Hair Coloring. The fashions of the nineteen twenties emphasized youth and natural hair dyes were a way to get rid of the gray.

1. Using these two recipes for covering grey: Convert both to ounces.
2. What percentage of each dye is either tea or coffee?
3. Convert the measurements from ounces to grams for solids and milliliters for liquids.
4. The perfect dye recipe is for 4 inches of hair. Measure your hair and figure out how much of each dye you need to make. Include the water, tea and coffee amounts

Natural dye #1

• Two teaspoons of black tea leaves
• One cup of water

Natural dye #2

• 8 tablespoons of coffee
• Two cups of water

Problem C: The availability of electricity to the public led to the market of household appliances. The refrigerator was introduced in 1927. Many of these early refrigerators contained toxic gasses as the coolant including; sulfur dioxide, methyl chloride, or ammonia.

1. Find the molar mass of each of these gases; sulfur dioxide SO₂, methyl chlorideCH₃Cl, and ammonia NH₃
2. Each refrigerator had 2 ounces of coolant. Convert ounces to grams and solve for how many moles of each coolant were in the refrigerator.
3. The more modern refrigerator use Freon, CCl₂F₂as a coolant as it is much less toxic, and they hold up to 6 ounces of coolant. Calculate how many moles of freon are in the modern refrigerator.

Problem D: Make up your own word problem from something you found in your study of the Harlem Renaissance or from looking up items for this problem set or other science tasks.

Science Option 2:  Choose one of the four categories; Fashion, Medicine, Prohibition, or Music.  Within the category you chose is an invention.  Research answers to the embedded questions about this invention and its impact on the times of the Harlem Renaissance.

Select one of the following:

1. a)Fashion; For hundreds of years cotton, linen, silk, and wool fibers were woven into fabrics for the manufacture of textiles.  After the turn of the century new inventions such as Rayon, Mercerizing, and the Zipper accompanied and were incorporated into fashion trends during Harlem Renaissance.

Choose one of these inventions.  Explain the Chemistry and/or Physics behind its manufacture/function. In what ways did this invention alter fashion, style and human behavior.

1. b) Many medical discoveries happened at the time of the Harlem Renaissance, including discovery of human blood types, insulin, and the antibiotic penicillin.

Choose one of these discoveries.  Explain the research that led to its discovery and what changes it had on the health industry, life expectancy, and human behavior of the times.

1. c) Prohibition gave rise to the manufacture of bootleg alcohol.  Most all of this ‘bootleg’ ‘moonshine’ was created not in a chemist’s lab but in a makeshift location hidden from law enforcement.  Manufacture of this product was a dangerous undertaking for both the manufacturer and the drinker of the alcohol produced.

Look into the process of creating and then distilling alcohol. What physical properties of the alcohol where used to concentrate it and increase its ‘proof’?

What practices made the distillation process so dangerous?  What by-products produced and additives added could make the alcohol deadly to consumers?

1. d)Amplified music became popular in the 1900s with the invention of the vacuum tube.  Before then, all music came from the sounds produced by the instruments themselves, with amplification, the sounds heard came not from the instruments, but from a vibrating cone of paper which could fill a room full of dancing people with sound.

How does this hundred plus year old electronics technology work? What is the physics behind its function?  What chemical elements are necessary to manufacture an amplifier?  What were the first musical instruments to be amplified?  How did amplified music change the behavior of humans?
