Knowledge, Labor & the World Around 1750 — Problem set, Grade 9
Five focused units, followed by an evidence workshop, chapter review, and chapter quiz.
Review the key ideas
Scientific Change: Observation, Models & Global Knowledge
Copernicus, Galileo, Kepler, Newton, and many others developed and tested models within networks of instruments, texts, patrons, and debate. A model is an explanation tested against evidence, not an opinion accepted because its author is famous. Religious commitments and scientific investigation often coexisted.
Enlightenment Debates: Rights, Power & Exclusions
Locke, Montesquieu, Rousseau, Voltaire, and others argued about different questions and had distinct contexts. Claims about reason or rights coexisted with slavery, colonial power, gender restrictions, and selective inclusion. These contradictions are part of the history, not details to omit from a celebration of progress.
Atlantic Slavery: Institutions, Resistance & Evidence
Racialized hereditary chattel slavery treated people as property and restricted freedom through law and violence. Enslaved people sustained relationships, knowledge, and resistance under coercion. Studying the system requires precise institutions and actors without reducing captives to numbers or assigning collective guilt to present-day groups.
The World Around 1750: Silver, Production & Unequal Connections
Silver, textiles, sugar, and other goods linked production, taxation, finance, and consumption. Potosí and other mining centers depended on specific labor and administrative arrangements; Manila connections linked American silver with Asian markets. The route of a valuable object cannot stand for every household’s circumstances.
Global History Capstone: An Evidence-Based Comparison
The task is to make and test a claim, explain a mechanism, consider a plausible alternative, and acknowledge a limit. Students can use the course’s background, labeled cases, source studies, and timelines. Outside purchases, personal disclosure, public posting, and agreement with an adult’s politics are not required.
Problem 1
Answer and explanation
The reported motions challenge the universal claim about Earth-centered orbits if the bodies orbit Jupiter. They do not alone establish every planet’s orbit or a complete theory of motion. Repeated observations and predictive models provide further tests.
Separate the recorded motions from a broader inference.
Connect the observation to the particular universal claim.
Identify other predictions and repeated observations needed.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 2
Answer and explanation
An observation can challenge a claim while leaving several alternatives. State what the instrument reveals, how reliable it is, and which prediction is tested. Scientific change involves accumulated evidence and revision rather than one hero proving everything at once.
Problem 3
Answer and explanation
The proposal may distribute powers while retaining narrow participation. Institutional checks and inclusive voting are separate dimensions. Assess each through the specified rules rather than assuming one constitutional feature guarantees every kind of equality.
Identify institutional division.
Compare eligibility separately.
Avoid inferring universal participation from checks on power.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 4
Answer and explanation
Identify the claim, reasons, audience, and exclusions. Distinguish a normative proposal from a report of existing practice. A text advocating rights does not establish that the writer’s society already granted them universally.
Problem 5
Answer and explanation
The recorded difference is 45 people, or 15 percent of departures. Without categories and complete records, it cannot be assigned wholly to one cause. Quantitative precision must not disguise uncertainty or erase the people behind the figures.
Subtract 255 from 300 to obtain 45.
Compute 45 ÷ 300 = 15 percent.
Check deaths, transfers, definitions, and missing records before attribution.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 6
Answer and explanation
Explain the particular system’s legal status, inheritance, compulsion, and enforcement. Consumer demand is a contributing condition, not a substitute for identifying the people and institutions organizing violence and profit. Economic explanation does not excuse coercion.
Problem 7
Answer and explanation
The listed remainder is 50 units before other costs. It does not establish net profit or fair compensation. Labor status, wages, prices, obligations, and missing costs are necessary to assess conditions and distribution.
Subtract the listed 20 and 30 from 100.
Identify omitted wages, finance, other costs, and labor conditions.
Distinguish accounting remainder from welfare and final profit.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 8
Answer and explanation
Trace stages with dated evidence and distinguish voluntary exchange from forced labor. A profitable final sale does not establish fair conditions at every earlier stage. Prices and taxes also affect how benefits and burdens are distributed.
Problem 9
Answer and explanation
A citizenship comparison might distinguish broader status from equal public power. An officeholding comparison might distinguish a learned ideal from access to education. Each needs dates, specific institutions, and limits; no ranking of peoples or prescribed political conclusion is required.
Select one dimension and comparable settings.
Connect a rule or institution with evidence of access or limits.
State what additional evidence could refine the conclusion.
Response criteria
- Describe the historical context and institutions accurately.
- Connect relevant evidence to an explained conclusion.
- Represent particular perspectives without stereotypes or invented testimony.
- Identify an evidentiary limitation or a distinction that qualifies the claim.
Problem 10
Answer and explanation
Use comparable evidence and criteria. A law from one setting and a palace from another may answer different questions; explain that asymmetry. A manageable comparison can acknowledge a missing type of evidence rather than pretending the records are equivalent.
