In this special topic, youth learned that all living organisms are composed of cells, from just one to many trillions, whose details usually are visible only through a microscope.  Students used iPads that had been converted to microscopes by their teacher, Randall Summy. He did this for $10 apiece by adding a stand and an additional lens.  Students conducted an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.

​In the video below, Randall Summy describes how he created the stands to use iPads as microscopes.
