A Microscope Medley for High School Students

Abstract

ABSTRACT Microscopy is crucial to much of biophysics. The variety of approaches to imaging exemplified by contemporary microscopes is remarkable, yet this breadth is generally unknown to students, limiting perceptions of biology, physics, and related fields and of potential career paths. We therefore created and implemented an outreach activity as part of a day camp that especially targeted low-income high school students. The students engaged with 3 very different microscopes: a simple transmitted light microscope; a light sheet fluorescence microscope; and a newly invented multicamera array microscope. With these instruments, we examined subjects such as transgenic zebrafish larvae with fluorescent immune cells, contrasting the various instruments’ capabilities, including resolution and field of view. Pre- and postactivity questions showed that the activity succeeded in expanding students’ understanding and appreciation of the varied aims and abilities of modern microscopes and moreover led to discussions of model organisms, biophysics, and science funding. Additional activities briefly illustrated the nature of digital images and mathematic manipulation. I describe here the activities and goals, as well as ways they can be generalized and implemented at other institutions with access to different sorts of imaging tools.
