At what temperature does yeast feel most comfortable? In our Yeast! lab, we will examine yeast and its peculiarities. Experiment for a group of 5 to 6 students (recommended for middle school).
Felix has a problem! He wants to bathe his pet, the yeast Yeastie. But his instructions got wet and the water made parts unreadable. Now he doesn’t know at what temperature Yeastie feels most comfortable. He can still see from the instructions that it is a two-digit number and that the last digit is a 5. He also thinks the bathing temperature was between 20°C and 50°C. Can you help Felix?
Embark on a search for the temperature optimum! You can read what this means in the knowledge box below.
You can find out at what water temperature the yeast Yeastie prefers to splash around with an experiment. The experimental procedure is explained in the video below:
You can record your results on the following worksheet.
What did your investigations reveal? Where is the temperature optimum for yeast? Write us your results in the comments.
The Yeast! materials were created in cooperation with the upper secondary profile Ecosystem Research of the Goethe School Harburg under the direction of Olaf Zeiske.
