Time to start putting some skills into practice. We will be examining the characteristics of life in the lab using yeast. Everyone knows that yeast is alive, even though it looks completely inert when you take it out of the package.
Your assignment is to come up with an experiment to demonstrate that yeast possesses the characteristics of life. Choose just one characteristic to focus on. This experiment needs to be set up, performed and completed (with clean up) in one class period. Think about:
- variables and constants
- control and experimental groups
- quantitative vs qualitative evidence
- equipment and materials needed (limited to whatever is available in the lab)
- what information needs to be recorded for your (brief) write-up
Before leaving class choose 2-3 other people to work with. For HW, write up a brief procedure addressing the points above (this can be done collaboratively).
