n this simple procedure, grains of rice are used to model small
organisms, and students act as predators selecting food during limited time spans. Over a number of generations,
the proportion of grains of rice of each colour in each population will change if students select one colour in preference to another. This is a simple model for natural selection resulting from predation.
Be sensitive to the fact that some students may find it harder to distinguish colour contrasts than others; they could be distressed by finding fewer grains of rice, or attaining slower rates of population change. Using a range of colour combinations limits the likelihood of this being noticed.

One significant divergence of this model from ‘real’ situations is that the colours of the new organisms in each generation are in the same proportion as the original population. In nature, it would often be the case that new organisms would have features in number proportional to the most recent parent generation. If your students can cope with the arithmetic of this (including rounding up and rounding down where necessary) you could add this feature to your method.
Another weakness of the model is that the prey is static and identified by the predator largely on the basis of colour, with form and movement making a relatively low contribut
