Heliocentric vs. Geocentric Models

Vocabulary

Astronomy: the study of the universe
Heliocentric: sun center
Geocentric: earth center
Ptolemy: Came up with the theory that earth was the center of the universe.
Copernicus: proposed that the sun was the center of the universe
Galileo: concluded that the sun was the center of the universe
Revolution: when earth move in an orbit around the sun.

Translation in French: Astronomy - Astonomie

                                 Heliocentric - Héliocentrique

                                 Geocentric - Geocentrique

                                 Revolution -Révolution

Summary

      A long time ago before the Scientific Revolution, people used the bible or theory from famous philosophers to conclude their hypotheses. In regards to the universe, a philosopher named Ptolemy suggested that the earth was it's center. This theory is called the Geocentric Model, Geo meaning earth and centric meaning center. Years after Ptolemy's hypothesis, another philosopher named Copernicus proposed that the sun was the center of the universe. Galileo concluded Copernicus theory of the earth moving around the sun. This is called revolution when earth moves in an orbit around the sun. Copernicus and Galileo's theory are known as the Heliocentric Model. Helio meaning sun and centric meaning center. This kid is why astronomy is important, the study of the universe, it permits us to conclude more reliable hypothesis and to know better about the world we live in.

Critical Thinking Question: How is Earth Affected by Movement?

Earth's movement around the sun (revolution) causes us to have seasons. Additionally, the fact that earth is tilted causes a part of it to receive direct, indirect or the same amount of sunlight depending on where it's situated around the sun. The different seasons are winter, spring, summer, and fall. Earth's movement (rotation) also causes us to have day and night. Finally, the earth and the moon movements cause us to have tides.  The moon's  gravity causes the ocean to bulge away from the earth. The rotation of the earth along with the moon's gravity abilities causes ocean tides to change. We have higher and lower tides in a day.

Reflection

When doing this project, I enjoyed making models while listening to music. However, every task was not as much fun to deal with. What I found the most challenging was putting the video together with the best clips of the ones we captured. From doing this project, I learn how to put together video parts to make one film in Imovie. One thing I could have done to improve my work is making the models we were using much smaller therefore they would have been easier to fit in the camera screen. As a result, the movie would have come out much better.
