Part 1: Do Now (5 minutes)
Directions: Read the prompt below and write a 5-8 sentence response.
Prompt: The Loophole. Imagine a school rule says: "All students must be treated equally." The Principal then decides to create two separate lunchrooms. Room A is for students with blue eyes. Room B is for students with brown eyes. The Principal claims, "You are being treated equally because both rooms have tables and chairs. You are just separate."
In a complete paragraph, answer: Is the Principal telling the truth? Can you truly be "equal" if you are forced to be "separate"? How does being forced into a separate room make you feel about your status in the school?
Sentence Starter: The Principal (is/is not) telling the truth because... Even if the furniture is the same, being forced to separate implies that... If I were forced into a separate room, I would feel...
Part 2: Analyzing the Sources
Directions: Analyze the two documents below and then answer the questions that follow.
Source 1: Majority Opinion, Justice Henry Billings Brown (Adapted Excerpt, 1896)
Original Text | Simplified Text |
"The object of the [14th] amendment was undoubtedly to enforce the absolute equality of the two races before the law, but... it could not have been intended to abolish distinctions based upon color, or to enforce social, as distinguished from political, equality..." | "The 14th Amendment was definitely meant to make the races equal before the law (Political Equality). But, it was NOT meant to stop people from seeing color, or to force the races to mix socially (Social Equality)." |
"Laws permitting, and even requiring, their separation... do not necessarily imply the inferiority of either race to the other... If one race be inferior to the other socially, the Constitution of the United States cannot put them upon the same plane." | "Just because a law separates the races, that doesn't mean one race is inferior (worse) than the other. If one race is socially inferior, the Constitution cannot fix that or force them to be on the same level." |
Source 2: Dissenting Opinion, Justice John Marshall Harlan (Adapted Excerpt, 1896)
Original Text | Simplified Text |
"Our Constitution is color-blind, and neither knows nor tolerates classes among citizens. In respect of civil rights, all citizens are equal before the law..." | "Our Constitution should not see color. It does not allow for different 'classes' of people. When it comes to rights, every citizen is equal." |
"The arbitrary separation of citizens, on the basis of race... is a badge of servitude wholly inconsistent with the civil freedom... The thin disguise of 'equal' accommodations... will not mislead any one, nor atone for the wrong this day done." | "Separating citizens just because of their race is like a 'badge of slavery.' It goes against freedom. We can pretend the train cars are 'equal,' but that is a thin disguise (a lie) that won't fool anyone. We have done a wrong thing today." |

Part 3: Exit Ticket (5 minutes)

Prompt: The decision in Plessy v. Ferguson established the doctrine of "Separate but Equal." In a detailed paragraph, explain why this phrase is a contradiction (a lie).
