Students will learn the role of bacterial fermentation and evaluate the effect of fat content, sugar content (lactose), and temperature in bacterial fermentation as they make yogurt. Grades 6-8 

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

This 26-minute program from the Gee Whiz in Agriculture series explores a dairy food processing plant that makes many of our favorite foods, such as cheese, butter, and ice cream. Why "milk does a body good" and why it's considered nature's most perfect food are emphasized. A direct comparison of the nutrient values of milk and soft drinks are made, along with other nutritional considerations. This video can be purchased on DVD or accessed on YouTube.

This 27-minute DVD teaches students where milk comes from, how milk is transported and processed, and how milk contributes to a nutritious diet. Order this DVD online from agclassroomstore.com.
