Our science class was introduced to the independent study of astronomy. We were assigned to choose a topic from astronomy, come up with at least 3 essential questions, research and answer them, and create a presentation. I choose to do the independent study on solar systems because I wanted to have an insight on the planet I live on, so that leads to the solar system.
What is the solar system?
The solar system is a collection of eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune) and their moons in an orbit around the sun. It also consists of the planets’ satilittles, numerous comets, moons, asteroids, meteoroids, dwarf planets, the interplanetary medium, and very thin gas.
What is the relationship between the sun and planets?
Planets closer to the sun are relatively small, composed of mostly rocks, more dense, and have few or no moons with higher temperatures. Planets further away are relatively large, mostly gaseous, ringed, less dense, and have many moons with cooler temperatures. The planet’s speed up when they are near the Sun.
Where are we in the universe?
In the universe, our solar system is located in the Milky Way. Specifically, Earth is at the edge of the spiral arm called the Orion Arm (Orion Spur). Furthermore, the Milky Way is located in a supercluster of 100,000 galaxies called the Laniakea.
For the project, I decided to do a physical presentation. I thought that science fair theme poster and model would be best to present my knowledge on the solar system. My poster was split into three sections, for each essential questions. The sections contained my answers to the questions and pictures. I planned to do a model of the solar system, the sun and eight planets. The model wasn’t to exact scale, but it gave you a brief idea of which planet is bigger and what the color of the planet is.
