  1. Galileogalilei title By Brooke Agius Grade 5 Alpha

  2. Galileo Galilei • Shortly after the death of Copernicus, the next great Astronomer was born. His name was Galileo Galilei. Galileo was the first Astronomer to use science to find out what the Universe is made of. Copernicus was right when he said that the Sun and not the Earth was at the centre of our Solar System, but he was only guessing. Galileo was not going to guess. • Galileo Galilei

  3. In 1609, Galileo heard about a new invention in Holland called an eye-glass, which was a sort of primitive telescope. He decided to improve this eye-glass and build atelescope to be able to look at the Universe. Up until now people had only been able to guess what the Universe was, but Galileo was actually going to look at it and find out the truth. • Galileo Galilei’s telescope 

  4. Galileo saw many things with his telescope. He looked at the Milky Way and discovered that it was made up of millions of stars, each at a different distance from the Earth. If the Universe was really a glass sphere, then all the stars would be at the same distance from the Earth. The Solar System 

  5. When he looked at the Moon he discovered mountains, valleys and craters. Everyone at that time thought the Moon was also a perfectly round ball. Galileo discovered that it was not. • The moon  

  6. He noticed that the planets Mercury and Venus pass through phases just like the Moon. The only way they could do that is if they circled the Sun, and not the Earth. Venus Mercury 

  7. And most importantly of all, Galileo discovered four moons around Jupiter. This meant that everything in the Universe did not circle the Earth. He could clearly see four moons which circled Jupiter. • Jupiter and its moons 

  8. In addition to these discoveries, Galileo also discovered that everything falls at the same speed. If you jumped off a bridge at the same time as an elephant you would both hit the water at the exact same time. Galileo did not throw an elephant off a bridge, instead, he dropped two round balls off the Leaning Tower of Pisa. One was very heavy, and one was light. Both hit the ground at the same time. Galileo Galilei Reading 

  9. The most important thing about Galileo is that he was not guessing. He could clearly prove to anyone that what he had discovered was true. Galileo Galilei showing people that he is saying the truth 

  10. That is all I can tell you! • That is all I can tell about the amazing Galileo Galilei and all the adventures and how he discovered that the Earth is not atthe centre of our universe..
