Video experiment: What’s your limit?

How do extremophiles survive in apparently hostile environments? Watch students investigate the effect of temperature on the rate of respiration of yeast by measuring the production of carbon dioxide bubbles

Questions for discussion

  • Can you do your own analysis with the data?
  • How would differences in salinity or pH change the rate of respiration?
  • How might you investigate this?
  • What would you expect to happen? Why?
