Measure volumes, temperature and optical densities. Design an experiment to measure the effect of environmental variables on population growth. Safety Students should wear goggles and aprons at all times. Questions to Ask During Pre-lab 1. In this lab you will grow a yeast culture.
Yeast can follow glycolysis with alcohol fermentation.
Yeast produce carbon dioxide 2. How might we design an experiment to see if we are correct. Accept many different approaches. Divide the class into groups of 4-5 students.
