For the foods unit in intro to ag, I bought eight gallons of milk: two gallons of skim, two of 1%, two of 2% and two of whole milk. The students were to taste each type from four jugs with labels and then record the look, taste and how it felt in their mouths. Then, they were to identify the type of milk from four mystery jugs. These jugs only had numbers and no labels.
As soon as I brought out the mystery jugs, the students began guessing out loud which one was which based on the color of the caps. They hadn’t gone on for long before one of the students said, “Knowing her, she probably switched the caps.”
That was my high school class. In one of my eighth grade classes, when I brought out the mystery jugs, one student furrowed his brows and began pointing and tried to identify the milk by just the caps. The student next to him stopped him and said, “Knowing her, she probably switched the caps.”
