Place twenty bacterial cells in each of three identical flasks full of nutrient broth. Then, place each flask in an incubator set at 10°C, 20°C, or 30°C. Finally, measure the number of bacterial cells in each flask every twenty minutes for four hours.
<span>An experimental design would be the most appropriate assuming she has access to the appropriate materials. She could set up an experiments where she has some cells and in one batch of cells she could raise the temperature and in the other batch she could do nothing. Then she can compare the cell division rate.</span>
