This lab provides students an opportunity to observe a yeast population at different stages of growth. By staining the cells with methylene blue, students can identify living cells and graph these cell counts over time. After careful counting, students compile their data as a class and generate a graph that allows them to identify the carrying capacity of the yeast.
This product includes teacher tips, lab procedures, a whole-class data sheet, and a student handout. There is no answer key, because data is variable, but students will see a carrying capacity in their data.
