Physical Science Unit: Water Beach Vacation Lesson 12 Engineering Design Problem: Beat the Heat Part 3: Testing a Cooler:

In this engineering design problem, students will have the opportunity to apply what they
learned about the changes water undergoes when it changes state through heating and
cooling by designing their own cooler. Students will be asked to use the engineering design
process to design a cooler that will reduce the melting of frozen water in hot temperatures
at the beach. Students will need to design and build their cooler, test their materials, and
justify their design decisions. In this lesson students will test their cooler’s effectiveness in
keeping ice from melting. In subsequent lessons students will improve their designs.

Physical Science Unit: Water Beach Vacation Lesson 14 Beat the Heat MEA Part 1: Setting up the Cooler Experiment:

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.
