Engineering Design Challenge: Designing an efficient solar shower Participating group members $($Write legibly$)$ : $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ Grading of each part will be based on its completeness, creativity and substance. Define the problem: $1)$ Considering building a solar shower where no gas or electricity is available, define the goals for the system like what it should be done and list criteria for success of each goal like what needs to be considered for each goal. $($You certainly want your solar shower to work as efficiently as possible.$)[20$ points$]$ Develop Solution: $2)$ Draw clearly a sketch of your best design for an efficient water heater to meet the goals you defined. Label all the parts, including the materials of which they are made and their colors. $[30$ points$]$ Assess the Solution: $3)$ Write an explanation in two parts for why your design will work efficiently; that is$,($a$)$ why will your design do a good job of initially warming the water and $($b$)$ then keeping it warm until shower time? Focus on how your choice of materials$/$colors $($a$)$ maximizes the transfer of energy into the water to warm it up$,$ and $($b$)$ minimizes the transfer of energy away from the water to keep it warm. You must explain these in terms of the heat transfer mechanisms: heat conduction, IR radiation, convection, and$/$or absorption of light. $[30$ points$]$
