These authors believe that the use of a good digital camera to record observations during a hands-on experiment can make the relationship between experimental variables more concrete for students. Examples are provided in chemistry, earth science, biology and physics. The example in physics addresses the use of the camera for indirect measurements such as the height of a tree. Since digital imaging is common in most cell phones (which almost all students own) the need and cost of cameras may not be an issue.
