Product Details

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 at the crossroads of biology, chemistry and nutrition, 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 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 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.

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.

Performance Expectations

MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-LS1-3: Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-LS1-3: Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
