*(sample answer/sketch) 15. What medium - liquid, or gas - a sound wave will travel through fastest? Explain your reasoning. Sound will travel fastest through a solid. The particles of a solid are tightly arranged. Therefore, the sound wave can easily propagate (move from one particle to the next). 16. Below is the Engineering Design Process. Given the following scenario, choose 2 steps of the process and explain in detail how you would carry out those steps. (4 points) Scenario: Design a more energy-efficient lighting fixture. sample answers: Step 2: Research the Need or Problem: look at current lighting devices and how they work, research energy-efficient lighting devices and explore how to alter existing devices Step 4: Select the Best Possible Design: Create a design matrix, then use the objectives and constraints you’ve adopted to choose the best design.
