This is the photo of the class at the end of our tour of the ethanol plant in Gibson City, IL.
Due to restrictions, we couldn't use our tablets to take pictures of things other than the students, or collect data. An app that would be great would be one that has icons represnting all the parts of ethanol production randomized on the screen. Through the tour, students drag the icons into a correct order and submit their flow chart.
I'm trying to do this via a general flow chart app.
