The Science of the Cookie: Why Does it Crumble?

Purpose of the Activity

This activity is designed to stimulate the mind and the senses through the familiar and comforting topic of baking. It encourages cognitive engagement by exploring simple scientific concepts in a fun, accessible way. The activity also promotes social interaction, triggers positive memories associated with baking and food, and provides a delightful sensory experience through smell, touch, and taste.
