Mrs. Poland, a teacher at Roosevelt Middle School, filmed the combination of Yeast and sugar with time lapse photography of a balloon filling up with air that the Yeast was exhaling.  
 
She also filmed the combination of Yeast and sugar with time lapse photography of Bromthymol Blue (BTB) changing from blue to yellow over time as the Yeast consumed the sugar and the gas they gave off was piped through the BTB solution. 
 
Her purpose for doing this was to be able to help students make sense of the information they had learned after the lab and to be able to relate further learning back to the visual data that she had collected. As many students at Roosevelt Middle are English Language Learners, she strives to capture as much visual information as possible to help the students to learn the content.
