Galileo and Experimental Science questions: Pg 9-11 What are the steps of the scientific process that the book mentions? The parts of science that we practiced were observing, recording, analyzing data, taking measurements, and sharing with class mates. 2. Why didn’t early scientists actually perform science? What did they do? Early scientists didn’t actually perform science because they couldn’t question authority. What they did was observe and rely on what previous scientists had done. (they had to believe what they were told because the kings word was law.) 3. How did things change about 400 years ago? About 400 years ago things changed because scientists began experimenting to see if the observations they made were correct.

Galileo and Experimental Science questions: Pg 9-11 4. What Changed Galileo’s mind about being a doctor? Galileo discovered that he didn’t always agree with what he was told and that all the things going on around him were more interesting. 5. What did he discover about the lamps in church? Galileo discovered that the lamps swung back an forth in a certain amount of time depending on the length of the chain and that it didn’t matter whether it was a partial or full swing. 6. After observing the lamps, what did he use to prove what he was seeing? Galileo used Math to help prove his observations of the lamps.

Galileo and Experimental Science questions: Pg 9-11 7. What was another major difference between Galileo and previous scientists that allowed him to share his ideas with others easily? Galileo made himself different from other scientist by recording notes and drawings from his observations and experiments in his journals and notebooks. 8. How did Galileo achieve his true fame? Galileo’s true fame came through the study of astronomy. 9. Because of his beliefs and observations (that turned out to be true) what happened to Galileo? Galileo was put on house arrest for the remainder of his life because he refused to take the kings word as the truth. 10. How was Galileo later honored for his discoveries and achievements? In 1989 NASA honored Galileo by launching a space probe bearing his name. It sent back photos of the four moons Galileo first saw in 1609. The moons are now known as the Galilean moons.

Galileo Galilei The Father of Modern Science Inventor, scientist, physicist, mathematician, astronomer and philosopher "Galileo, perhaps more than any other single person, was responsible for the birth of modern science.“ ~ Stephen Hawking “The laws of nature are mathematical.” ~ Galileo Galilei

Galileo Notes Galileo Galilei - Italian Major accomplishments 15 February 1564 – 8 January 1642 Major accomplishments Changes the way science was done by creating the scientific method and using experimentation Was one of the first to test ideas through Experimentation Began record keeping using notebooks and drawings Connected Math and Science by finding out about the link between chain length and a swinging lamp This led too several experiments with pendulums

Galileo Notes Cont… Astronomy He is credited with being the Father of modern Science and astronomy Built the first modern telescope in 1609 (did not invent it just improved it) His telescope is also called a spyglass He was able to magnify objects from 3x to 30x discovered several moons of Jupiter They are now called the Galilean moons Io, Europa, Ganymede, and Callisto

Galileo in trouble Challenging the Church and King Galileo challenged all the beliefs of the time and ended up in opposition to the Church and King (even though he was correct) Published his book in 1632, Dialogue Concerning the Two Chief World Systems His view that the Sun not the Earth was the center of the solar system (heliocentrism), along with several others, got him placed on house arrest till he died This was open ended meaning he could still do research and have visitors but could not leave, speak publicly, or publish work.
