Students taste test four different milks while comparing color, texture, taste, and cost. In addition, students examine four milk food labels and complete a table comparing calories, fat, and calcium found in the milks. Students make cottage cheese by heating milk to the proper temperature and adding an acid (vinegar) to speed up the separation of curds and whey. Grades 3-5

In this lesson students apply their knowledge of physical science to dairy products to determine if the changes that take place when turning milk into cheese, butter, yogurt, ice cream, whip cream and other dairy products, is a physical or chemical change. Grades 9-12

Students explore the scientific processes used to make the crops we grow and the livestock we raise (commodities) into some of the foods we eat every day. Students will discover how science and technology work together to create foods like pickles, bread, yogurt and more! To engage further in the topic, students will make their own cheese using enzymes produced through the fermentation of genetically engineered yeast.  Grades 6-8
