Patterns in Pixels

This activity (page 2) draws upon a familiar, computer-based concept related to visual resolution: pixilation. The sharpness of a digital image is determined by the density of illuminated points on a screen. The smaller the points, the more that can fit into one centimeter and the greater the clarity of an image. Learners evaluate photos of varying resolution to understand how increased data density helps to create clearer patterns. This activity is a introductory lesson for a health-themed program on human biochemistry, technology, and medicine. [Activity is publicly available through a web crawler capture on]
