Our Place in Space

This activity consists of a series of 15 cards that include images of astronomical objects on the front and information about these objects on the reverse. The card backs include information on the location of the object, its size, and its distance from Earth. Teachers should print out the cards (preferably in color) and laminate them so that the information on each object appears on the reverse side of the image of that object. Once you have assembled the cards, they can be used either as fact cards or for a variety of activities in the classroom including:

  1. Put the Universe in Order: Distance to Earth In this activity, students can organize the objects cards by their distance from Earth starting with the closest object to us and continuing to the furthest. You will probably want to omit the Solar Neighborhood card because the card depicts stars in very different parts of our galaxy. Here is the order of the objects from closest to furthest: International Space Station, Moon, Mars, Sun, Saturn, Pleiades, Orion Nebula, M Globular Cluster, Large Magellanic Cloud, Andromeda Galaxy, one of the Galaxy Clusters (Stephan’s Quintet or Virgo Supercluster; Although Stephan’s Quintet is further from Earth it is impossible for a student to know this just from knowing that the image shows a galaxy cluster), Hubble Deep Field
  2. Put the Universe in Order: Size In this activity, students can organize the objects cards by their size starting with the smallest object and continuing to the largest. You will probably want to omit the Solar Neighborhood card because the card depicts stars in very different parts of our galaxy.

Here is the order of the objects from smallest to largest: International Space Station, Moon, Mars, Saturn, Pleiades, Orion Nebula, M13 Globular Cluster, Large Magellanic Cloud, Andromeda Galaxy, Stephan’s Quintet, Virgo Supercluster, Hubble Deep Field

  1. Object Classification In this activity students can classify the objects in a variety of ways. You can even challenge your students to come up with their own categories of classification. Here are just a few ideas:
  2. classify by object type: is the object a planet, moon, star, galaxy, etc.
  3. classify by location in the universe: is the object in our solar system, the Milky Way Galaxy, or beyond
  4. classify by age: have students research the age of each object and place in order from youngest to oldest
