3 Describe and/or Sketch the Object What Materials Do You Think Make It Up? What Questions Do You Have About It? Copyright

4 2.1: Materials Science Lab Your Material: Fill out the data chart with the tests that you tried and how your material performed. Properties of Your Material (List Some Adjectives) Observations Describe the Test How the Material Performed Copyright

5 This material would work best for: This material would not work for: Copyright

6 3.1: Paper Airplane Mini-Design Challenge Name: Date: Period: Our team s building material: Fill out the data chart with the tests that you tried and how the airplane performed. Flight/Crash Test Trial # How the Material Performed Copyright

7 Observations and Sketches Copyright

8 How Did Your Airplane Perform? Strengths Weaknesses Copyright

9 Complete the Pugh chart for your particular design solution. Problem: What are the best materials for our new airplane? Criteria Your Team s Solution Lightweight Strong Minimal Number of Seams and Fasteners Flies Well Total Points What Surprised You? What Do You Still Want to Know? Observations and Sketches Copyright

10 4.1: Early Name: Date: Period: Define Composite Sketch Daedalus Design for a Pair of Wings (Branches, Feathers, Wax) A composite is Recipe for a Composite Material: + = Composite Recipe for Daedalus and Icarus Wings: + = Composite Wings Recipe for Bricks: + = Composite Bricks Recipe for a Carbon Fiber Composite: + = Carbon Fiber Composite Copyright

11 4.2: Candy Composite Challenge (Part 1) Recipe for a Candy Composite: + = Candy Composite Fill out the first column of the Pugh chart with the criteria that the class developed. Use the chart to help you decide which possible solution/design your team thinks will best meet the criteria. Problem: What are the best materials for our Candy Composite? Criteria Possible Design #1 Possible Design #2 Possible Design #3 Total Points Sketches and Notes Copyright

12 Fair Test Describe the fair test we will use to test each team s candy composite prototype. Sketch You Chosen Design Prototype Show the candies you chose and how you laid them in the pan. Copyright

13 4.3: Candy Composite Challenge (Part 2) Record your observations during the testing of your prototype. How did it perform? Which group(s) s candy composite best met the design criteria? Why do you think they were successful? What design strategies do you think were unsuccessful? Why? If you could redesign your candy composite, what would you do differently next time? Copyright

14 Sketch Your Redesign Copyright

15 5.1: Cardboard Challenge Name: Date: Period: Describe the Test How Did the Cardboard Perform? Sketches Copyright

16 How did the cardboard perform? What were its strengths and weaknesses? What do you think were the design criteria for the material scientists who developed corrugated cardboard? How did they want the material to perform? Did your own ideas about the design criteria change after you tested the cardboard? How? Copyright

17 Use words and sketches to define the three major types of material strength. Compressive Strength Tensile Strength Shear Strength Copyright

18 6.1: Textile Technology Name: Date: Period: Sketch magnified views of the samples in our model of how carbon fiber composites are made. Fiber Yarn/Tape Thread Spool/Spindle Sweater/Mat Sketch magnified views of the weave patterns in two types of fabric. Label them. How are they similar/different? Copyright

19 What is special about carbon fiber composites that make them a good material choice for the design of an airplane? How does weaving change the structure and performance of a material? Sketches and Notes Copyright

20 7.1: Engineering Design Process Diagram Name: Date: Period: Copyright

21 7.2: Design Challenge Design Task Name: Date: Period: Who are the members of your design team? Sketches and Notes What have you been asked to design? Who or what is the design for? Copyright

22 7.3: Design Challenge Background Knowledge Name: Date: Period: Describe the science concepts that you need to understand as part of this design. Sketches and Notes Describe any personal experiences you have related to this engineering task. What would be helpful to know? Where could you find this information? Copyright

23 7.4: Design Challenge Brainstorm Possible Solutions Name: Date: Period: Brainstorm some ideas for different weave patterns Sketches and Notes Brainstorm some ideas for different ways of building your prototypes. Choose two designs that your group will build and test. Think about the design criteria and constraints. Why did you choose these designs? Copyright

24 8.1: Design Challenge Optimize the Design for the Weave Test all four prototypes that you built. Record your data in the table below. Weave #1 Experimental Control: Plain Paper Towel Weave #2: Plain 1/1 Weave Weave #3: Your own design Weave #4: Your own design Build and Test of Design Prototypes Prototypes (add a description for each one) # of pennies supported before failing What happened? Why do you think it happened? Weave #1 Weave #2 Weave #3: Weave #4 Copyright

25 Sketches and Notes What didn t work well? What could be improved? How will you revise your designs? Copyright

26 Redesign one or more prototypes and test them again! You can do this as many times as time allows. Build and Test of Redesigned Prototypes Redesigned prototypes (add a description of each one) # of pennies supported before failing What happened? Why do you think it happened? Which design performed the best? How did you decide that this was the best design? Did it meet all the criteria of the design task? Copyright

27 Draw a picture of your optimized design. This is the one you will turn into a Paper Podge Composite. Make sure to show the weave pattern and make notes about any special construction techniques. Sketches and Notes Copyright

28 Why is failure important in the engineering design process? What did you learn about your designs when they failed? How did each prototype s failure help you improve your design? What surprised you today? Why? Copyright

29 9.1: Design Challenge Optimize the Design for Your Paper Podge Composite Test your Paper Podge Composite using the same fair test that you used when testing the weave prototypes. Record your data in the table below. Build and Test of Paper Podge Composite Prototype # of pennies supported before failing What happened? Why do you think it happened? Paper Podge Composite Sketches and Notes What didn t work well? What could be improved? How would you revise your design? Copyright

30 9.2: Design Challenge Design Implementation Name: Date: Period: Does your optimized design meet all the criteria of the design task? Sketches and Notes Did your optimized PPC design create any new problems when it was implemented? How can you address these? How do you think your Paper Podge Composite material would perform when applied to the product that the class chose? Copyright
