Observation is a skill used to critically examine details of something.  This skill is often dulled when the object is something that is seen often or is known to the observer.  One way to become more aware of the aspects of an object is to spend time looking at it.  In Life Science we often spend time looking through the microscope or identifying a plant or animal by its physical characteristics.  It is very helpful to students when we spend time drawing the specimen they are studying.  This activity helps them notice details as they take time to try to sketch it on paper.  This exploratory lesson combines the skill of drawing and the scientific knowledge of the object.  Mrs. Collins the art teacher and I enjoy co-teaching students when opportunity allows.  The attached 30 second video shows 8^th grade Life Science students spending an afternoon drawing with Mrs. Collins and me at Lichterman Nature Center.
