Lesson 1: The Scientific Revolution

Grade 7 students explore the Scientific Revolution as part of Pengi Social Studies Chapter 10, learning how thinkers like Copernicus, Galileo, and Newton shifted the foundation of knowledge from traditional authority to observation and evidence. The lesson covers key developments including Copernicus's heliocentric model and the emergence of the Scientific Method. Students analyze how these breakthroughs reshaped understanding of the natural world during the Early Modern period.

Section 1

Roots of the Revolution: Empiricism and Rationalism

Before the 1500s, people decided what was true based on ancient Greek authors or the Bible. The Scientific Revolution changed this by introducing a new way of thinking. Two philosophers laid the groundwork. The English thinker Francis Bacon promoted Empiricism, arguing that scientists should ignore old authorities and instead gain knowledge through observation and experimentation.

Meanwhile, the French mathematician René Descartes championed Rationalism, emphasizing the use of logic and reason ("I think, therefore I am"). These two approaches merged into the Scientific Method, a step-by-step process of formulating a Hypothesis, testing it with experiments, and analyzing data to reach a conclusion.

Section 2

The Heliocentric Theory: Copernicus and Kepler

For over a thousand years, everyone believed the Geocentric Theory—that the Earth was the unmoving center of the universe. In 1543, Polish astronomer Nicolaus Copernicus shattered this view with his Heliocentric Theory, proposing that the sun stood at the center and the Earth revolved around it.

This idea was radical and dangerous. Later, German astronomer Johannes Kepler used math to prove Copernicus right, but he corrected one detail: planets do not move in perfect circles, but in oval-shaped paths called Ellipses. This mathematical proof made the heliocentric model undeniable to scientists, even if the public remained skeptical.

Section 3

Galileo and the Church

Italian scientist Galileo Galilei built his own Telescope and turned it to the sky. He saw mountains on the moon and moons orbiting Jupiter, visual proof that the universe was not perfect and unchangeable as the ancients claimed.

Galileo published his findings, but they contradicted the Catholic Church’s interpretation of scripture. In 1633, the Inquisition put him on trial for Heresy. Threatened with torture, Galileo was forced to recant (take back) his beliefs and spent the rest of his life under house arrest. His story symbolizes the conflict between religious authority and scientific evidence.
