Solar System, Galaxy, Universe YEAR 1 SCIENCE

Class Opener  In the upper right square of your title page, complete the following:  Title the square with “Exploration”  Answer the following question using as much detail as possible: Explain how space tools help to contribute to space exploration

What are the differences between a solar system, galaxy, and universe?

Solar System, Galaxy, Universe

 SPACE consists of many bodies, such as planets, moons, stars, meteors, comets, and asteroids.  Astronomers have organized SPACE into 3 groups.

SOLAR SYSTEM  A collection of planets that orbit around a star, along with asteroids, meteoroids, and comets  The planets may contain multiple moons that orbit them

GALAXY  A huge group of stars, solar systems, dust, and gas held together by gravity

GALAXY  There are 3 types of galaxies: - Spiral (spiral outwards and spin) - Elliptical (shaped like flat disk) - Irregular (smaller and do not have a shape)

Spiral Galaxy

Elliptical Galaxy

Irregular Galaxy

 Our galaxy is called the Milky Way and is spiral shaped

UNIVERSE  Can be defined as all of space and everything inside of it

Note Review  Highlight the 3 major terms: solar system, galaxy, and universe  With your blue utensil, chunk your notes  With your green utensil, underline the definitions of solar system, galaxy, and universe -Update your glossary (solar system, galaxy, universe) -Continue working on your book- due next Monday!
