Saskatchewan produces nearly 20 kinds of field crops which can be categorized into 5 groups. There are many varieties within each type of field crop. For example, there are more than a thousand varieties of wheat grown throughout the world. Grain samples can be obtained from local grain producers, elevators or seed cleaning plants. An excellent resource is the CN Grains Kit which is available to schools for a very minimal cost.
Students develop understandings from a variety of sources.
Students should show their finished displays to other members of the class. The class can use the individual displays to obtain information about some different kinds of plants. Students can collect different kinds of leaves and group them based on similarities. Crayon rubbings can be produced to show an interesting relief pattern of the leaf structure. The leaves can be examined carefully with hand magnifiers.
