In this article, Claas Wegner, Phillip Weber, and Stephanie Ohlberger share how they have been teaching about variation and staple food crops in the teaching unit they tested with 8- to 10-year-old children. They started by showing some products made from crop plants and asking the class to carry out a simple comparison of similarities and differences. At the end of the sequence of lessons shared in this article, the children should be able to describe what their breakfast cereal or sandwich is made from, as well as appreciate the importance of grasses as staple foods.
