Experiment #1: Monitoring Algal Growth in Water Samples

Emma: ‘I think that we could use the centrifuge to monitoring algal growth in water samples!’ 

Dr Smith: ‘Thank you for your enthusiasm, Emma, but using the centrifuge to monitor algal growth isn’t the most appropriate approach. In this experiment, you only need to measure turbidity or absorbance of the water containing algae—those steps don’t require high-speed separation of components. 

You: ‘It seems that you confused spectrophotometry with centrifugation Emma.’ You point to the spectrophotometer near the centrifuge and Emma nods in agreement. 

Dr Smith: ‘It’s wonderful to see you exploring possibilities—considering all tools shows initiative. Just remember to match each experiment’s objective with the method best suited to achieving it.”
