This activity draws on the geometry of silos, structures commonly found on local farms. A specification from a manufacturer forms the basis of the scale model making. The activities engage students with scale and ratio, the volume of a cylinder, measurement conversions, graphs and substitution into formulae.

Experimental design for agriculture relies heavily on Latin and Graeco-Latin squares to cope with different fertility patterns found in different parts of a given experimental growing space. All three activities engage students in systematic analysis, the need for careful recording and proof. Four types of wheat also draws attention to rotation and reflection.

Many species of plant take to the air to disperse their seed and germinate away from their parent plant. Understanding how seeds disperse helps agriculturalists propagate self-dispersal crops and manage weed populations. Flight testing involves students in measurement, data collection and recording, and the calculation of averages. It also gives good first-hand experience of the mathematical idea of range.

A probability model is developed from historical data which is then used to simulate the breeding of rabbits in a field and consider the likely damage to the farmer’s crop. In this activity, students analyse data and work with probabilities and probability models, draw bar graphs and compare results.
