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 develop confidence in their lab skills and gain practical experience as they measure the amount of protein and carbohydrate and verify their findings with the information provided on the nutritional 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 Teacher Notes with sample data and answers to questions, and all necessary chemicals and consumable supplies.
Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs. Fresh skim milk (one pint per class) is required, but not provided. Two 50-minute lab periods are recommended for completion of this activity.
