Today in class we were assigned to find out what the Foucault's pendulum is. Ms. D explained what it is and how it works. Here is the definition of the Foucault's pendulum: "The Foucault's pendulum is an instrument devised by a Frech physicist Jean Bernad Leon Foucault in 1851 to prove that the Earth rotates on its axis."
It is a tall pendulum (weight suspended from a pivot so it can move freely) free to move in a vertical plane. The direction it spins rotates with time because of the Earth’s rotation. The pendulum stays going in a straight line, BUT the building it is in is on Earth and the building actually moves with Earth and the swinging pendulum does not.
After this we had to choose 3 themes in astronomy that we would like to work on for a future lab.
20 minutes before the end of the class, Ms. D said that we will start a lab. We had to be with the partner number 7 (on the clock). The Lab purpose is to find out "How the relationship between the sun, Earth and Moon determines moon phases, solar eclipses and lunar eclipses."
5 minutes before the end of the class Ms. D gave to each of us a pencil and a white ball which represented the Moon. There were 4 lamps in the class representing the Sun. What we had to do was to try to put the "Moon" in different positions to see how much light it could reflect on the Earth (us).
Here is a video that describes the Moon Phases.
