1. Engineering Design Process

2. First, let’s review the “Scientific Method” 1.Ask a question 2.Research 3.Procedure/Method 4.Data Observation 5.Conclusion

3. Engineering Design Process  Very similar to the steps of the Scientific Method

4. 1. ASK  Identify and Research a Need

5. 2. IMAGINE  Develop Possible Solutions

6. 3. PLAN  Make a Prototype

7. What is a prototype?  A test model of the product  Allows engineers to see if their design works the way it should

8. Describe a situation in which a prototype would be helpful. 1.2.3.

9. 4. CREATE  Test and Evaluate

10. 5. IMPROVE  Modify and Retest the Solution

11. Engineering Design Process

12. Independent vs. Dependent Variables ONE thing in an experiment that changes Changes because of the independent variable. It “depends” on the variable Independent Variable Dependent Variable
