Astro Lesson Summary 6/4/18

Today we learnt about Kepler's Laws. The first law: The Law of Orbits , all planets move in elliptical orbits, with the sun at one focus. The second law: The Law of Areas, a line that connects a planet to the sun sweeps out equal areas in equal times. The third law, the Law of Periods, the square of the period of any planet is proportional to the cube of the semi major axis of its orbit. Kepler's laws were derived for orbits around the sun, but they apply to satellite orbits as well.

This is one of Kepler's laws, the Law of Orbits. The elliptical shape of the orbit is a result of the inverse square force of gravity. The eccentricity of the ellipse is greatly exaggerated here.

This is one of Kepler's laws.This empirical law discovered by Kepler arises from conservation of angular momentum. When the planet is closer to the sun, it moves faster, sweeping through a longer path in a given time.

Next week we will be launching water rockets. I can't participate in the launch, but I can aid in the building of the rocket.

ASM Event

During the ASM event in February of last year , I had helped to carry equipment from SST to the ASM. We took the radio equipment and stored it in a moving van. Me and Mr.Tan sat together in the truck with the truck driver to bring the equipment to Marina Bay. We arrived early so we unloaded our things and waited for their arrival. Once they had arrived , we brought all the equipment to the basement of MBS that had an underground connecter connecting to the storage areas of the museum. We took a service elevator to the floor that the exhibition was held on and we set our things up. From there we checked that everything was ready and we left to come the next day to present to the general public who visited.

Thinking back on it , I believe that the hard work of transporting and reassembling the equipment was worth it in the end as we got to experience something that most students are unable to do. Entering the museum during off hours and presenting to the general public in a museum.

Solar Eclipse 2016

At the Solar Eclipse event, I helped out by bringing my class to the rooftop and showing them how to use the apparatus to view the sun being blocked out by the moon. After the eclipse ended we brought the students back to their classes and did fun quizzes with them till their next period. The day before the event we conducted two dry runs in order to make sure that everyone knew their role and that we could conduct the event smoothly and quickly.

Omni Theater Science Centre Field Trip

At the Science Centre we went to see a movie about astronomy. There was a guide person that commentated over parts of the movie and asked us questions about space. During the movie , a fellow CCA member and I took down notes during the movie as it would help us during CCA activities.
