  1. Presentation Description This presentation will be given before the Engineering students transition from their cardboard prototype designs to the actual building of PVC vehicles. My presentation shows 6,7& 8 students the steps they will need to take during our next two meetings. • Technology/Engineering, Grades 6–8 • Materials, Tools, and Machines • 1.1 Given a design task, identify appropriate materials (e.g., wood, paper, plastic, aggregates, ceramics, metals, solvents, adhesives) based on specific properties and characteristics (e.g., strength, hardness, and flexibility). • 1.2 Identify and explain appropriate measuring tools, hand tools, and power tools used to hold, lift, carry, fasten, and separate, and explain their safe and proper use. • 1.3 Identify and explain the safe and proper use of measuring tools, hand tools, and machines (e.g., band saw, drill press, sander, hammer, screwdriver, pliers, tape measure, screws, nails, and other mechanical fasteners) needed to construct a prototype of an engineering design. • Engineering Design • 2.1 Identify and explain the steps of the engineering design process, i.e., identify the need or problem, research the problem, develop possible solutions, select the best possible solution(s), construct a prototype, test and evaluate, communicate the solution(s), and redesign. • 2.2 Demonstrate methods of representing solutions to a design problem, e.g., sketches, orthographic projections, multiview drawings. • 2.3 Describe and explain the purpose of a given prototype. • 2.4 Identify appropriate materials, tools, and machines needed to construct a prototype of a given engineering design. • 2.5 Explain how such design features as size, shape, weight, function, and cost limitations would affect the construction of a given prototype.

  2. Building your ROV The PVC Pipe Frame 6,7& 8 Junior Engineer Club

  3. What you need Safety Glasses Ratchet Cutter Ruler

  4. Begin Construction………. Cut PVC to the lengths you designed in your cardboard prototype.

  5. Fittings Choose fittings that hold the lengths of PVC in position to match your approved design.

  6. Design Examples Advanced Basic Rectangle Frame Remember a more intricate design does not always produce a better result.

  7. Drill Weeping Holes Once you have your final design you must take the PVC apart and drill weeping holes. Reassemble your frame. The weeping holes will help your ROV sink. You then have your “wet frame”.
