Objectives After this session you will: 1. Better understand the Engineering Design Process (EDP) 2. See connections between EDP, standards and Curriculum 3. Apply EDP to inquiry Based Activities

Opener In your Handout: Match the Description with each step in the Engineering Design process.

Engineering Design Process Identify and Define Communicate Solution Refine Evaluate Solution Gather Information Communicate Identify Implement Solution Alternatives Select Best Solution

Engineering Design Process Identify and Define Communicate Solution Identify and Define Refine ▪ What are the goals and requirements for the design? ▪ What Gather are the constraints (time, materials, …)? Evaluate ▪ Identify the users (customers) Solution Information ▪ Is this a new design or an improvement to some existing design? Communicate Identify Alternatives Implement Solution Select Best Solution

Engineering Design Process Identify and Define Communicate Solution Refine Evaluate Solution Gather Information Communicate ▪ Are there any existing designs worth evaluating? ▪ If this Identify is an innovation on a current design: ▪ What are the good features of the current design? Alternatives ▪ What improvements seem necessary? Implement Solution ▪ Talk to the key people involved and/or experts in the field. ▪ Review existing data and collect more if necessary Select Best ▪ Research any unfamiliar principles Solution– learn what you don’t know

Engineering Design Process Identify and Define Communicate Solution Refine Evaluate Solution Gather Information Communicate Identify Alternatives Implement ▪Brainstorm Solutions Solution ▪Generate multiple ideas for the design. Don’t settle on the first solution that appears feasible. ▪ Don’t critique or rule out any design ideas. Select Best ▪ Be creative Solution and innovative – a rich set of diverse ideas will lead to a better final design.

Engineering Design Process Identify and Define Communicate Solution Refine Evaluate Solution Gather Information Select the Best Solution Communicate ▪ Does the design meet all the requirements and constraints? ▪ Evaluate each design idea in terms of cost, time/difficulty to Brainstorm Implement implement, Solutionsease of use for consumer, safety, maintainability… Solution ▪ If possible, use computer simulation (mathematical modeling) to evaluate the effectiveness of each potential design. Select Best Solution

Engineering Design Process Identify and Define Communicate Solution Refine Evaluate Solution Gather Information Communicate Identify Alternatives Implement Solution Best (a working model used to test a Build a. Select prototype Solution design concept) of the selected design.

Engineering Design Process Identify and Define Communicate Solution Refine Evaluate Solution Gather Information Evaluate Solution Communicate Test the design for functionality, quality, and safety. Does the design meet Implement all of the Solution requirements and constraints? Identify Alternatives Select Best Solution

Engineering Design Process Identify and Define Communicate Solution Refine Evaluate Solution Gather Information Testing often reveals that the initial design needs improvement(s). Engineering design is an iterative process requiring a systematic Communicate approach for testing, evaluating, and refining in order to optimize the final design. Identify Alternatives Implement Solution Select Best Solution

Engineering Design Process Identify and Define Communicate Solution Refine Evaluate Solution Gather Information Communicate Identify Alternatives Good communication Implement Solution itself and within the design team with anyone else with a stake in the project is essential for success. Communication skills include the ability to Select listen as well as the ability to. Best write and speak well. Solution

Engineering Design Process Identify and Define Communicate Solution Refine Gather Information Once the final design has been developed, the “solution” Evaluatemust be communicated to the customer. Solution Appropriate documentation must be provided, and depending on what the Communicate product design is, some training might be required. Identify Alternatives Implement Solution Select Best Solution

EDP vs the Scientific Method EDP State your question Identify and define Do background research Gather Information Formulate your Hypothesis Identify Alternatives Design experiment Select the best solution Test hypothesis with experiment Implement Solution Analyze Results, Draw conclusions Evaluate solution Revise Hypothesis Refine Communicate Results Communicate solution How are these the same OR different?

Standards alignment NGSS Practices of Science and Engineering Practices of Science and Engineers Asking questions (for science) and defining problems (for engineering) Developing and using models Planning and carrying out investigations Analyzing and interpreting data Using mathematics and computational thinking Constructing explanations (for science) and designing solutions (for engineering) Engaging in argument from evidence Obtaining, evaluating, and communicating information
