This resource is so simple to use and understand that it works well in a variety of settings. Teachers can use it as a starting point for beginning to talk about cells and the building blocks of all living things or to assess students' knowledge about the relative size of various microscopic cells and organisms. It also gives students a visual reference for some of the various structures that may be covered in a biology class. Additionally, it could be tied into a conversation about the role that microscopes have played in our understanding of things that cannot be viewed unaided by the human eye.
Finally, teachers also might use this as an exercise in mathematics to cover the difference in powers of ten (e.g., A paramecium is 210 x 60μm, while an antibody is 12nm. Which is bigger? By how much?)
