Great for a middle school or high school science lab to investigate nature of living things using yeast.
3 page lab investigation ready for students to complete.
Investigation: We have been studying the nature of living things in class. Today we will focus our investigation on yeast. Your lab group will set up a yeast culture in warm water to be used in this experiment. The plain culture (just yeast and water) will be added to test tube A. Sugar will be added to the culture in test tube B. You will measure the height of the foam that is produced over a 14-minute test period at 2-minute intervals.
