We're spoiling milk for science! The Blue’s the Clue Kit gives students the opportunity to investigate how different variables affect one of the most common foods they drink every day—milk. Through this experiment, students model the scientific process and consider how scientists and quality control workers ensure food safety.

The activity uses methylene blue dye to test how quickly milk “spoils” under different conditions, giving students a visible, hands-on demonstration of bacterial activity and food science in action.

    Blue's the Clue

    Makes the experiment a lot easier than gathering all the supplies and having it not work as well. Plastic tubes with caps are key! They aren't glass and you don't have to worry about them breaking.
