At the heart of the lesson is the "freezing method." Students combine cream, sugar, and vanilla in small jars, which are then placed inside larger containers filled with ice and salt. The introduction of salt is crucial; it lowers the freezing point of the ice, allowing the cream mixture to freeze into a solid state through rapid heat exchange. This practical demonstration makes complex scientific principles like endothermic reactions tangible for nine- and ten-year-olds. Instructional Precision Beyond the science, the unit focuses on the importance of sequencing and precision Students learn that salt lowers the freezing point
