America as a new nation and America as a fragile nation: both ideas had an enormous shaping influence during Washington's presidency, a period of his career that, oddly, doesn't usually receive much attention. I think that in the minds of most Americans, when the Revolution ends and George Washington is no longer a general, he somehow becomes a block of marble at the head of our government-the ultimate figurehead-not really doing much and certainly not feeling much as a real human being.

Yet in fact, Washington as president could be a very savvy political player, and he certainly had a whole host of feelings and reactions as a very real person in a very difficult situation. He wasn't always sure how to handle things; he sometimes made mistakes. He was sometimes awkward, embarrassed, or nervous.

Just read this account of his first address to Congress just after taking the oath of office in 1789, as witnessed by Senator William Maclay. Maclay writes:

this great Man was agitated and embarrassed more than ever he was by the levelled Cannon or pointed Musket. [H]e trembled, and several times could scarce make out to read, tho it must be supposed he had often read it before... When he came to the Words all the World, he made a flourish with his right hand, which left rather an ungainly impression. I sincerely, for my part, wished all set ceremony in the hands of the dancing Masters, and that this first of Men, had read off, his address, in the plainest Manner without ever taking his Eyes From... the paper[,] for I felt hurt, that he was not first in every thing.

Explanation:

After the French and Indian War, which was fought between 1754 and 1763, the country of France lost all of its territory in North America, including its territories in present-day Canada and the United States. The war was fought between France and Great Britain, and as a result of the war, Great Britain gained significant territory in North America, including all of France's holdings in the region.

Hypothesis

In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.





Procedure

Complete your hypothesis (above).

Identify the independent (test) variable and the dependent (outcome) variable:



Practice using the computer model. Select each marker to see what it does. Here is a summary you can refer back to as you complete your experiment.

Carbon Dioxide Emissions Slider: You will use the arrows to change the amounts of carbon emissions.

Time Step Size: This will allow you to view the data every 5 years or every 10 years.

Start Over: Use this to reset the model if needed.



The current carbon emissions are 9.8 gigatons, or 9.8 billion tons. Complete all three scenarios to find out what happens to the global temperature if these emissions stay the same, decrease, or increase over the next century. Follow the instructions in the Data section of this report.



Data

For each scenario, record the carbon dioxide emission rate and the global temperature. The data for the years 1960–2010 are already filled out for you.



Scenario One: Carbon dioxide emissions stay the same

Set the carbon dioxide emissions rate to 9.8 gigatons.

Set the time step size to 10 years.

Select step forward until you have the data through the year 2110.

Record the data in the table below.

Over the course of Module 4 we looked at a number of challenges that the young United States faced after the signing of the Constitution and the inauguration of George Washington. In an essay of at least 5 full and complete sentences, identify and then discuss at least three (3) challenges that the country faced between 1788 and 1825. A suggested format would be to write an opening sentence, identify/discuss three challenges over the next three sentences, and then wrap up with a closing sentence.

The French wanted control of the Ohio River Valley for?

A. The Abundant Rivers
B. Fur trading
C. To help Native Americans
D. To build new settlements

Answers

Answer:

B. Fur trading

Explanation:

The French wanted control of the Ohio River Valley because it was an important area for fur trading. The region was home to many fur-bearing animals, and the French established trading posts in the area in order to trade with the Native American tribes who lived there. The French also wanted to prevent the British from gaining control of the region, as they saw the Ohio River Valley as an important part of their colonial empire.

B. Fur Trading because the area had a lot of animals with fur.

In all, 70 delegates were appointed to the Constitutional Convention, but out of that 70 only 55 attended, and only 39 actually signed. Some simply refused, others got sick, and still, others left early. One of the most famous reasons why certain delegates didn't sign was that the document lacked a legitimate Bill of Rights that would protect the rights of States and the freedom of individuals. Three main advocates of this movement were George Mason, Elbridge Gerry, and Edmund Randolph.

Also, John Dickinson who is officially listed as a "signer," didn't sign the Constitution himself. Dickinson fell ill during the Convention and couldn't be there on signing day. So, he authorized George Read to sign for him.
