Please read the below scenario and
answer the questions


1.
2.
3.
You have two objects, one weighs 4 lbs and
the other weighs ½ lb.
You then drop both objects from 7 feet above
the ground.
Which object will strike the ground first?
Explain why you believe that?
Design an experiment to prove your
hypothesis.
Objectives
1.

3.
Compare and contrast geocentric and
heliocentric theories
Describe the scientific method
Describe the contribution to science of:
A.
B.
C.
D.
Copernicus
Galileo
Bacon / Descartes
Newton
Medieval View




Earth-centered
view
“Geo-centric”
Taught through
ancient writings of
Aristotle
Supported by the
church
Nicolaus Copernicus


Polish cleric
Studied the
movement of planets
Heliocentric Theory
Sun centered view
 Planets revolved
around the sun
 Proven mathematically

Nicolaus Copernicus





Polish cleric
Studied the
movement of planets
Heliocentric theory
Published his findings
in 1543 (last year of
his life)
His student was
Galileo
Scientific Method
 Question
 Hypothesis
 Experiment
 Conclusion
Galileo Galilei
Italian scientist
 Observed
common events
 Asked Questions
 Made amazing
discoveries!

•
•
Motion experiments
- Dropping objects
Objects of different
weights fall at the
same speed
•
Built one of the first
telescopes
-
•
Observed the planets
Jupiter's moons
Supported
Copernicus’s ideas
Conflict with the Church




Galileo’s discoveries
supported Copernicus
Differed from church
teachings
Arrested and tried by
the Pope (1633)
Confessed to being
wrong…
“With sincere heart and
unpretended faith I abjure, curse
and detest the aforesaid errors and
heresies (of Copernicus) and also
every other error…contrary to the
Holy Church…”
“But it does move!”
Galileo Falls to the
Church
Please have your homework out…
Answer these questions on your own paper.
(see your homework, question/section 2)
1. Why did Galileo’s findings anger the church?
2. What was Galileo forced to do? Describe.
3. Describe how the interest in science led to a new
approach called the Scientific method.
Isaac Newton
Law of Gravity
•
Describe the heliocentric theory
•
Describe the geocentric theory.
•
Explain how gravity works? Why do things get
pulled toward the earth?
Law of Gravity: Isaac Newton
Newton


English
Studied Physics


Law of Gravity

Published in 1687

How objects move
Discovered why gravity works
Every object attracts other objects
This attraction depends on:


Mass of the objects
Distance apart
Gravity
What was revolutionary about the
Scientific Revolution?
Questions, testing,
proof



-
Francis Bacon


-
Rene Descartes
New interest in science led people to ask
questions
Needed a standard method to prove the
answer
2 scientists developed a new way to prove
Used a logical approach to science
observation and test

Used mathematics and logic
Applied to thinking

The new ‘approach’ called a ‘method’

Scientific Method
Geocentric and
Heliocentric
1. Divide your paper in ½
• On one side draw the geocentric theory
• On the other, draw the heliocentric theory
2. Next to each drawing, list 3 people or terms
associated with each theory (i.e. Aristotle =
geocentric)
