Designing a Thermal Cup

Students recommend the best material for 7-11 store’s cup -- one that keeps hot beverages hot, and cold beverages cold. Using a computer model, students test different cup materials and gather evidence to support their recommendation. This piece of instruction covers the second day of the activity. In the first day, they started the activity by defining the challenge, making predictions about cup materials and creating an experimental plan. They may have begun testing their materials. On this day the students will share their ideas from day one and complete their testing and recommendation.
