1. Bellwork Sept 16, 2015 1. An sporting company designs, builds, and sells whistles to be used by referees and coaches. This company wants to redesign their whistles so that they are louder so that players can clearly hear the whistle during a noisy game. After the company comes up with several design ideas, what is the next logical step for them to take? 2.A technology company has identified the need for a smaller laptop computer that weighs less, but they do not have enough knowledge about how to build it. What would be the next logical step engineers would take to design and produce this laptop computer? 3.What equipment measures weight? 4.What are the units for weight? 5.A student wants to test how the concentration of phosphorus in a fertilizer affects plant growth. In designing this experiment the independent variable would most likely be the...? SPI 0807.T/E.1 to 2 Engineering Design Process

3. Today's Plan Plan 1) Do and review Bellwork 2) Go Over Objectives 3) Quick Review Engineering Design Process 4) Notes on Prototype Testing 5) Study guide on Prototype and Engineering Design Process WRITE THIS IN YOUR AGENDA! Homework: Study Guide Sept 16, 2015 SPI 0807.T/E.1 (Prototype Testing)

4. TCAP Objectives SPI 0807.T/E.1 Prototype Testing Essential Learning Students will identify tools and procedures needed to test a prototype. Essential Question What are appropriate tools and procedures used in testing a prototype? Notes Science Instructions 1) First click on "View" from the top-menu bar. 2) Then click on "Slide Show" from the drop-down menu. 3) Then use the right-arrow button on your keyboard to advance through this presentation.

5. SPI 0807.T/E.1 Identify the tools and procedures needed to test the design features of a prototype (1) (3) (2) (4) (5) Notes Steps 4 and 5 are the steps of the EDP where we test our prototypes SPI 0807.T.E.1 (Prototype Testing) SPI 0807.T/E.2 (Eng. Design Process)

6. SPI 0807.T/E.1 (Prototype Testing) Engineering Design Process-Prototype Testing  The 4 th step in the eng. design process is testing your prototype  Often, the prototype does not work very well at first  Testing a prototype can be dangerous (see picture below)  By testing the prototype, the designers find problems to fix  They fix the problems and then test it again. They repeat this over & over. (This is step 5 of the eng design process.) Here is a picture of Orville and Wilbur Wright testing their prototype airplane Notes Science

7. SPI 0807.T/E.1 (Prototype Testing)  The procedures and tools for testing a prototype are dependent upon the type of technology and the purpose for that technology.  For Example: You would not test a new cell phone the same way you would test a new jet airplane or a new football helmet. Discuss These Questions: A) How would you test a prototype of a new type of eyeglasses? B) How would you test a prototype of a new type of headache medicine? C) How would you test a prototype of a new type of camping tent? SPI 0807.T/E.1 Identify the tools and procedures needed to test the design features of a prototype Notes Science

8. Notes SPI 0807.T.E.1 (Prototype Testing) SPI 0807.T/E.2 (Eng. Des. Process) Prototype Testing in the Movies -From the movie "Batman Begins" Story summary: Billionaire Bruce Wayne's parents are murdered by a criminal when he is boy. So he vows to fight crime as a vigilante when he grows to manhood. Yet he has no superpowers, so he instead uses technology devices to enable him to fulfill his mission. Science

9. SPI 0807.T.E.1 (Prototype Testing) SPI 0807.T/E.2 (Eng. Des. Process) In this scene Mr. Fox is showing Mr. Wayne a prototype of a special material called "memory cloth." Bruce later uses this cloth to make a cape that allows him to glide through the air Notes Science Prototype Testing in the Movies -From the movie "Batman Begins"

10. Prototype Testing in the Movies -From the movie "Batman Begins" Notes Science SPI 0807.T.E.1 (Prototype Testing) SPI 0807.T/E.2 (Eng. Des. Process) In this scene Mr. Fox is showing Mr. Wayne a prototype of a special vehicle called "the Tumbler." Bruce later paints it black and uses it as his "Batmobile" vehicle. Does it come in black? How do you like it?

11. SPI 0807.T.E.1 (Prototype Testing) SPI 0807.T/E.2 (Eng. Des. Process) In this scene Alfred is testing the prototype of Batman's mask by hitting it with a baseball bat. It fails the test and breaks, so they must modify it and re-test it. Notes Science Prototype Testing in the Movies -From the movie "Batman Begins"
