Feel the Heat

 

 

 


Essential Question

What are the properties of a passive solar hot water heater that make it most effective?


Description

People have been interested in the moon since they first realized it existed and, with the Apollo mission, NASA was able to send humans there. In discussions about the possibility of going back to the moon, questions about living there arise. What would people need to survive the moon's harsh environment? During this engineering design challenge, students will work to build a passive solar hot water heater that could help humans survive the harsh temperatures on the moon. This activity gives students the opportunity to tackle this real-world problem by following the eight steps of the engineering design process to create, test and redesign their water heaters.


Additional Resources

  Classroom Resources:

 

  • Videos for Students:
    • Defining the Problem: This video shows a teacher explaining the problem to his students -- the design of a water heater.
    • Select a Solution: This classroom excerpt shows the teacher and students brainstorming and selecting a solution that they will pursue.
    • Design and Test Solution: This video follows students as they design, build and test the solution they chose. Two teams get very different results.
    • Refining the Design: Once the teams have results of their testing, they rethink their designs and make improvements.
    • Classroom Discussion -- Wrap-up: We listen in on the classroom discussion as the two teams analyze their newest testing results and hypothesize on potential future improvements.
    • Classroom Preview: This music video gives a fast-paced overview of the entire activity.
    • NASA Connection for the Classroom: This video is a resource that teachers can use to describe the NASA Connection and to introduce the design challenge to the students.
    • LRO: This video describes the Lunar Reconnaissance Orbiter and its mission in locating the best landing sites for long-term research on the moon. It introduces the importance of available natural resources like water ice, sunlight and certain minerals that can be used for manufacturing.
    • Repeatability: A fast-paced animated segment graphically explains the importance in the engineering design process of refining a design -- and reducing the possibility of failure.
