Build and Test

Use this sheet to help you build and test your prototype for moving water.




Build your model. You'll want to think about scale (the ratio of your master design and your model should remain consistent for all the parts), what materials you have at hand that can stand in for your master design's parts (particularly if you don't have access to a 3D printer), mobility, and water capacity. You may decide you need additional items or want to change your design. That is fine. Just make a new sketch and revise your materials list.

Test your model for how well it can move water. How much water can it move? Does it have any leaks? Are there any problems you can identify?




Based on your tests, you may decide to revise the model or prototype design to reach your goal. Prepare your design for your final test during the Design Challenge.


Final Test
List the results of your final test. Has your design improved?



Discussion Questions for after the Design Challenge
How did your team move water from one place to another?


Among all the teams, what worked best and why?


How did you change your design as you were working on it?


If you had to do it all over again, would your design change? If so, how would it change?


If you had to build your product for use in an area where it might be needed, are there things you'd need to change? What might you need to do differently? Are there questions you'd need to consider for long-term use or for the disposal of your product at the end of its lifespan?


How do you think working as a group helped you to complete this project?


What parts of the engineering design process did you use?
