Imagine that you could use a powerful microscope to observe each of the following objects and materials. The microscope allows you to see evidence of cellular structure. Sort each of the objects and materials into two categories: Not made up of cells (never made up of cells) OR Made up of cells (or was once made up of cells).



After sorting each of the objects, explain your thinking. Describe the rule you used to decide whether something was made up of cells or not.
