Some important details are missing or may contain minor errors.	Student accurately describes the concept of light years and relates it to the distance of the object being described.	Student accurately describes the concept of light years and uses clear, vivid examples, in addition to the object they identified, to convey the concept of vast distances in space.
Content Knowledge Understanding of a Cosmic Object	Student attempts to describe a cosmic object, as seen through Chandra.. Information is limited and/or may contain major errors.	Student describes a cosmic object, as seen through Chandra, by providing partial information such as formation, composition, or evolution of the object. Some important details are missing or may contain minor errors.	Student clearly and accurately describes a cosmic object, as seen through Chandra, including information such as formation, composition, and evolution of the object.	Student thoroughly and accurately describes a cosmic object, as seen through Chandra, providing details on the formation, composition, and evolution of the object.
Communication Use of a visual representation	Student attempts to create a representation of a Chandra image but fails to capture the details of the object and may contain major flaws.	Student creates a representation of a Chandra image that captures most of the details of the object.	Student creates a representation of a Chandra image that accurately captures the details of the object.	Student creates a vivid representation of a Chandra image that accurately captures the details of the object in a highly visually appealing way.
Communication Explaining concepts clearly	Student is generally ineffective in explaining their exhibit to the general public. Explanation may be confusing or too dense in terminology.
