Milk Is a Natural—Biology, Chemistry
and Nutrition Student Laboratory Kit
By: The Flinn Staff
Got milk? From glossy magazine ads to flashy billboards, the message to drink milk is all around us. Why is milk considered a nutritionally complete food source? In this real-world lab activity, students separate the protein and carbohydrate components of skim milk, analyze their properties and confirm their identity. Students gain practical experience as they measure the amount of protein and carbohydrate and verify their findings with the information provided on the nutrition label of skim milk. What better way for students to see how science affects their daily lives! Includes reproducible student handouts, detailed background information, complete Instructor’s Notes with sample data and answers to questions and all necessary chemicals and consumable supplies. Note: Fresh skim milk (one pint per class) is required but not provided. Two 50-minute lab periods are recommended for completion of this activity.
Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.

Physical Properties of Proteins—
Student Laboratory Kit
By: The Flinn Staff
Structure determines function—this is one of the most universal themes in biochemistry. What factors influence the physical properties of proteins and determine their structure and function? In this hands-on student laboratory kit, students examine the effects of acids and bases, inorganic salts, organic solvents and temperature on the physical properties of proteins. The dramatic results are visually impressive and allow students to see for themselves how sensitive proteins are to physiological conditions and to the addition of external agents. Students learn how these factors affect the interactions among amino acid side chains that are responsible for the stable three-dimensional structures of proteins—and thus change the actual shapes of proteins. Students observe that some changes are easily reversed and thus relatively harmless while other changes are essentially irreversible and lead to complete loss of protein function. The definition and applications of protein denaturation are also explored. Includes reproducible student handouts, detailed background information, Instructor’s Notes with sample data and answers to all questions and all necessary chemicals and consumable supplies needed.
Complete for 30 students working in pairs.
