The solar system unit was chosen to motivate and enhance students to learn about our solar system and its unique properties in space. Also, the unit was chosen to help students understand the relationship of the universe to the planets, moon, stars, Earth, and the Milky Way. The students will acquire scientific knowledge by applying concepts, theories, principles and laws from life/environment, physical, and earth/space sciences. I chose this unit because it allows students to explore/travel the solar system using the Internet.
