The Roaring Twenties (1920s)

The decade following World War I saw significant geopolitical and economic shifts:

• League of Nations (1919): Established to promote peace, though the U.S. did not join. Germany and the USSR joined later.
• Pact of Locarno (1925): Major European powers agreed to respect borders.
• Economic Recovery in Europe: Germany introduced a new currency and experienced deflation.
• U.S. Prosperity: Driven by industry, exports, loans to Europe, and a booming stock market.
• "American Way of Life": Characterized by consumer goods (cars, appliances), this lifestyle reached Europe primarily after WWII.

The Great Depression: An Abrupt End to Prosperity

The economic boom of the 1920s was largely fueled by speculation, leading to instability:

1. What Is Static Electricity?

Static electricity is the imbalance of electric charge accumulated on an object’s surface.

It is commonly observed in daily life, resulting in phenomena such as:

• Hair rising
• A balloon sticking to a wall

2. Atomic Structure and Electric Charge

Electric charge is determined by the components of the atom:

• Proton: Positive (+) charge (located in the nucleus)
• Neutron: Neutral (0) charge (located in the nucleus)
• Electron: Negative (–) charge (orbits the nucleus)

Charge states are defined by the balance of protons and electrons:

• Neutral Atom: Equal number of protons and electrons
• Positive Charge: More protons than electrons (net loss of electrons)
• Negative Charge: More electrons than protons (net gain of electrons)

3. Methods

• How is it used?
• What effects do the people in power have on others?

Supporting Arguments

• Thomas Putnam’s search for power by accusing people to get their land.

Control and Suppression

• Parris: "There is a faction that is sworn to drive me from my pulpit. Do you understand that?" (Miller 10)
• Those in power often use their authority to suppress opposition and protect their status.
• Parris is more concerned

Economic & Social Transformations (12th-14th Century)

Agricultural Production & Population Growth

Why did agricultural production increase from the 12th century?

Several reasons contributed to the increase in agricultural production. The cultivated area was expanded by clearing forests, draining wetlands, and cultivating new land. In some regions, the three-field crop rotation was introduced, leaving only one-third of farmland fallow. New techniques also facilitated agricultural work, such as the heavy plough, irrigation, windmills, and watermills. This increased production led to more available food, reduced famines, and improved public health. Consequently, the death rate decreased, and the birth rate increased.

While some argue that zoos help protect endangered species, their conservation efforts are often *ineffective*.

Ineffective Conservation Efforts

• Only a small percentage of animals in zoos are part of genuine breeding programs for endangered species.
• Even fewer are ever released back into the wild.

If zoos truly wanted to protect endangered species, they would focus on reintegrating animals into their natural habitats instead of keeping them in enclosures. In many cases, zoos prioritize popular animals that attract visitors rather than those that need urgent conservation efforts.

Prioritizing Profit Over Protection

Instead of keeping animals in captivity, resources should be directed toward:

• Protecting their natural habitats.
• Enforcing anti-poaching
