GALILEO GALILEI AND HIS DISCOVERIES

By Posy, Kathy, and Arlene

GALILEO’S BIRTH AND DEATH DATE

Galileo was born on

the 15th of February

1564 in Pisa, Italy.

Galileo died on the

8th of January 1642 in

Arcetri, Italy.

GALILEO’S TELESCOPE

Galileo made his first telescope in

1609. He didn’t really invent the

telescope. It was actually created

by a Dutch spectacle maker,(Hans

Lipperhey,) but when Galileo found

out he made his own. His magnified

objects twenty times, where as the

first one could only magnified

objects three times. Over time

Galileo slowly improved his

telescope.

GALILEO AND THE SUN

For years people thought the sun orbited around the

Earth. Nicoulas Copernicus made a scientific guess

that the Earth revolved around the Sun. A few years

after Nicoulas’s death, Galileo was born. In 1610

Galileo used his telescope to confirm Nicoulas’s

hypothesis. The Earth actually revolved around the Sun

instead of visa versa. He also discovered the moon has

creators. This to he discovered with his telescope.

THE SOLAR SYSTEM

THE PENDULUM

The pendulum was discovered by

Galileo. The way he discovered the

pendulum, is that one day Galileo was

bored , he was sitting in a church, and

he saw the candelabra swinging, that

gave him the idea of the pendulum.

With the pendulum he made the

pendulum clock, to tell time more

accuartly. The pendulum also came

into play in many other inventions.

WHAT WOULD TODAY BE LIKE WITH OUT GALILEO’S

DISCOVERIESIf Galileo hadn’t made his discoveries we wouldn’t

know the Earth isn’t the center of the universe, we

wouldn’t have a pendulum, or the pendulum clock,

and finally we would know little about the solar

system.

THANKS FOR WATCHING!
