Scientific Revolution:Scientific Method

The Scientific method is a serious of steps that scientists use to solve a problem. To do the first step of the scientific method you would need to identify a problem by observing things. Then for the second step you will need to make a hypothesis of what is going to happen. Then you would test the hypotheses to see if it is correct. If it's incorrect then you will have to do another experiment, with a different hypotheses. You will have to keep doing experiments until your hypotheses is right. This is the scientific method of solving problems.

For example Aristotle said that heavier objects fall faster than light objects. Then Galileo proved him wrong by dropping a very light object and a heavy object at the same time from the Tower of Pisa. Somehow it ended up that the objects fell to the floor at the same time.

Copernicus and the trial of Galileo

The geocentric theory is a Greek theory that Earth was the center of the universe. It was interesting to the astronomers that the rest of the universe would move around earth.The Sun, Moon, planets, and stars could be seen moving around Earth along circular paths day after day.

The heliocentric theory is a theory that states that the Sun is the central body of the solar system and perhaps of the universe.
The first evidence of theory was found in philosophers writings. It was around 6 century B.C. They said that earth was round from seeing eclipses of the moon. As we know now they were right. Earth's shadow on the moon is always shaped as a circle.

The Geocentric Theory came before the Heliocentric theory. The Heliocentric theory came from about the time of the Scientific Revolution. The theory as we can all see is true is the Heliocentric theory. The center of the universe is the sun.

Galileo Galilei was on trial for writing in a book his idea that the Earth was not at the center of the universe, that the sun was at the center. The Catholic Church believed in the Geocentric theory. They believed that the universe revolved around the Earth. Galileo was sentenced to house arrest.

Evolution v.s Creation

Creation is the belief that God created everything, all the world in 6 days. He created water, earth, other planets, the universe, people, pretty much everything that ever existed he created. He called light day, and dark night. On the 7th day it was a resting day, which is a Sunday.

Evolution is a belief that everything was created somehow. A widely held notion that all life is related and has descended from a common ancestor. For example the birds and the bananas, the fishes and the flowers are all related.

I believe in evolution because I think that all the world was created somehow someway, by something else.
