Storylab: Diffusion


This storylab was created for introductory biology for students who missed the Diffusion Lab in class.

The story is written from the perspective of a student who in experiencing the real lab. It describes how the lab is set up, by placing a bag filled with starch in a beaker full of iodine. The teacher in the story explains relevant terms, such as semipermeable, diffusion, and indicators. Questions at the end are similar to questions that students were required to answer in the classroom activity.

I started creating “storylabs” this year because so many of my intro students missed class. While the real lab is preferable, storylabs can be a substitute when students are unable to do the real lab.
