If possible, acquire a handful of wheat kernels from a local farmer or seed dealer. Hand them out so students can feel them and see what they look like. Share background information. 2. Draw a wheat kernel on the chalkboard, or use the worksheet illustration on an overhead projector. Discuss the endosperm, bran and germ of the kernel. Explain that normally in wheat processing, the bran and germ are removed, and the endosperm is ground into flour.
