2 Learn, Build & Modify Elements of an Inclined Plane There are two basic elements of an inclined plane. Identify the correct element in the spaces provided Purpose of an Inclined Plane Fill in the blanks below. 11. Purpose: 12. The inclined plane makes work easier by the amount of effort that must be applied to raise or lower a load. 13. To reduce the amount of effort needed to raise or lower an object in an inclined plane, the length of the slope should be. (extended or reduced) Build and Modify Place a check in the boxes below as the team completes each step. 14. Build Rokenbok Inclined Plane 15. Test Inclined Plane - Step Test Inclined Plane - Step 2 2

3 Build & Modify Understanding Mechanical Advantage Fill in the blanks in the statements below. 17. Mechanical Advantage exists when the force of a machine is than the force that was applied to it. 18. For a machine to create mechanical advantage, it must trade increased time or for reduced effort. Mechanical Advantage in an Inclined Plane Use the formula for calculating mechanical advantage to solve the problems below. Example 1 - Inclined Plane 19. Determine the mechanical advantage of the inclined plane in Example 1. Mechanical Advantage: Formula Length of Slope (120cm) Height of Rise (60cm) Mechanical Advantage = Slope Rise Example 2 - Inclined Plane Example B 20. Determine the mechanical advantage of the inclined plane in Example 2. Mechanical Advantage: Length of Slope (180cm) Height of Rise (60cm) Modify Inclined Plane Place a check in the box below as the team completes each step. 21. Modify Rokenbok Inclined Plane from 2:1 to 3:1 Mechanical Advantage. 22. Teacher confirms modification is correct. 3

4 Design & Engineer Design & Engineering Challenge Follow each step in the design & engineering process to develop a solution to the challenge. Place a check in the box as each step is completed. Fill in the blanks when necessary. 1. Identify The Challenge Challenge: Review. 2. Brainstorm Ideas & Solutions Discuss design ideas. Consider building components and cost. 3. Build A Prototype Build a working prototype of the design. 4. Test & Improve The Design Test & improve the design for performance and consistency. New challenge discovered: Review grading rubric and design. Consider ways to reduce cost. 5. Explain The Design Prepare to demonstrate and present the design to others. Review project grading rubric. Explain any unique design features that were included. Describe at least one new problem/challenge discovered during Step 4 (Test and Improve The Design) and how the team redesigned a new solution. 4

5 Design & Engineer Challenge Evaluation When teams have completed the design & engineering challenge, it should be presented to the teacher and classmates for evaluation. Teams will be graded on the following criteria: Specifications: Does the design meet all as stated in the design brief? Performance: How well does the design work? Does it function consistently? Team Collaboration: How well did the team work together? Can each student descibe how they contributed? Design Quality/Aesthetics: Is the design of high quality? Is it structurally strong, attractive, and well proportioned? Material Cost: What was the total cost of the design? Was the team able to stay on or under budget? Presentation: How well did the team communicate all aspects of the design to others? Grading Rubric Advanced 5 Points Proficient 4 Points Partially Proficient 3 Points Not Proficient 0 Points Specifications Meets all Meets most Meets some Does not meet Performance Design performs consistently well Design performs well often Design is partially functional Design does not work Team Collaboration Every member of Most members of Some members of Team did not work together Design Quality/ Aesthetics Great design/ Good design/ Average design/ Poor design/ Material Cost On Budget ($120 or Less) Slightly Over Budget ($ ) Over Budget ($ ) Significantly Over Budget ($141+) Presentation Great presentation/ well explained Good presentation/ well explained Poor presentation/ explanation No presentation/ explanation Points Total Points /
