The document provides instructions for a science investigation involving groups of students. The investigation aims to determine which material - Styrofoam, metal, or plastic - best keeps ice cream cold. Students will observe butter samples in cups made of each material that have been placed in hot water. They must record melting times, complete an online reflection, and clean up afterwards. Proper procedures and safety are emphasized.

12. The Scenario
“Saofiq and Farabi are in-charge of buying ice-
cream for the end-of-year class party in school.
However, they need to find a box to bring the ice-
cream to school. They managed to find a
Styrofoam box, a plastic box, and a metal box.
In which box should they bring the ice-cream to
qchool?”
