Experiment #3: Assessing Seed Germination Rates

Dr Smith: “Everyone, I see you’re gravitating toward the ‘Assessing Seed Germination Rates’ option. While that’s certainly a fascinating experiment, it doesn’t actually require the use of our centrifuge. Why do you think that is?’

Emma: ‘When we’re evaluating how seeds sprout and how their roots and shoots grow, the key measurements involve tracking their length or observing changes in structure under a microscope—there’s no need to separate out components by density.’ 

Dr Smith: ‘That’s correct! Remember, our goal in this lab is to figure out where the centrifuge is truly needed. Seed germination experiments only involve planting seeds and monitoring how they develop over time. That means no spinning of samples, no pellets to isolate, and no supernatant to collect. You’d be wasting both time and energy if you tried to apply a centrifugation step. So, while it’s a valuable study, it doesn’t help us learn the practical applications of our centrifuge. Let’s go back to our previous options and see which one genuinely calls for spinning samples at high speed.”
