this MEA, students will have the opportunity to apply what they learned about describing
the changes water undergoes when it changes state through heating and cooling. This MEA
is divided into four parts. In Part 1 of this activity, students will learn how to set up the
cooler experiment. They will watch a video and take notes. Students will also develop their
hypothesis in preparation to perform the experiment. In part 2, students will be asked to
use ice to test the coolers they designed in Beat the Heat Engineering Design Lessons.
Students will take measurements and collect data on their cooler. In part 3, students will
analyze the data they collected. Finally, in part 4 they will develop a procedure for selecting
the most effective cooler to keep water frozen the longest at the beach. In the optional
twist, students will need to take the mass of the cooler into account.
