Students should include a description and explanation of their model and summarize Project Summary: how the model performed during testing, including their calculations for work and power. Students must also include their technical diagram. 7 Presentation of Students will explain the results of how their waterwheel performed during testing Final Solution: and refer to the model and the technical diagram during the presentation. Students Step Solution(s) should present like they talking to the board of the engineering design firm and Communicate explain why their design is an efficient waterwheel. the Re-designing of Based on peer reviews, teacher input, and analysis of proposed solution, the the Prototype students are to re-design and rebuild a prototype of their design. Teacher Notes: Before the Activity: Review force, work and power. Drill 3/8-inch holes into the end of the two-liter bottle and the cap. This allows the bottles to spin symmetrically and freely about the dowel rod. (If you do not have the hole in the cap, the dowel rod will not spin symmetrically.) 8 Ideas: Step Can test waterwheels over a sink or container to capture the water Redesign Testing waterwheels outside is a good idea to prevent water from covering the floor Students can rebuild and change the distance from which they pour the water or use a different amount of weight.
