Goshen College Department of Art: The Conversation Game
March is Youth Art Month. Use this lesson plan to help your students develop what the author calls “self lists” that will give them ideas for their artwork. He describes the Conversation Game, which helps students become acquainted with others in their group. As the participants ask questions, they also answer those questions from their own perspective, beginning a recognition of their own values and beliefs. By developing their self-knowledge, they can then extend that knowledge to ideas for their art projects. Find suggestions for homework connected to the game and try the variations of the game. Even though this is slanted toward older high school and college students, the ideas could be distilled for middle school students too.

BioEd: The Science of Food and Fitness
There’s much talk about the childhood obesity rate and the risks of chronic illnesses in adulthood that this could affect. Use these activities to help students explore what makes up a calorie, how food provides energy, and how nutrients work in the body. One activity helps students calculate what their individual energy needs are. Another is a real eyeopener because it shows the difference between portion and serving. Students learn to visualize what the recommended serving on a food label actually looks like. They also find out whether what they are eating is meeting their nutritional needs. Finally they are challenged to make menus to meet the dietary requirements of people with different needs.
