Design Brief: (Day 2) Requirements: Your bridge should cross over an index card. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Your bridge should be 5 - 6 inches high. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Your bridge should 4 - 5 inches wide. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Your bridge should hold at least 100 pounds. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">You get one handful of popsicle sticks. <span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Questions: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">1. What is the strongest type of bridge? <span style="color: #71ff00; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Bridges made out of triangles <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. What bridge would work best for me? <span style="color: #ff1900; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Truss Bridge (Made out of triangles) <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">3. What geometric shape is the strongest structure<span style="color: #fffc00; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">? Triangle <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">4. Other questions and answers you may have:<span style="color: #00eeff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> None <span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Research Sites to Help You Answer the Questions Above: [|How Stuff Works:] [|Instructables:] [|Student Ideas:] [|Truss Bridge:] [|Building a Bridge:] [|eHow:]

<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">PLAN: (1/2 Day) <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">5. Use a blank piece of paper to draw a rough draft of your bridge. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">6. On your paper include why you think this bridge will hold the most weight.

<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">CREATE: (4 DAYS) <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">7. Did you use all of the glue, popsicle sticks and other materials appropriately? Yes <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">8. Did you work with your group members appropriately? Yes

<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">EVALUATION: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">9. Did you research bridge types? Yes <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">10. Did your bridge hold 100 pounds? Yes <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">11. How much weight did your bridge hold? 192 <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">12. What would you do differently next time? We should add more support in the center <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">13. Reflect on all the steps of the Design Cycle. What did you do well? What do you need to improve? (Notice that there are two questions, answer both of them!) <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Investigate: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">1.We did well by looking at different websites before deciding on how to build our bridge <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. We could have looked at pictures of bridges <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Plan: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">1. We discussed the design before finalizing the design <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. We could have used more triangles in the design <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Create: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">1. We followed the plan <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. We should have innovated it more and used more triangles <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Evaluate: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">1. OURS held more than a hundred pounds <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. If we used more triangles than the bridge would have held more weight <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">14. Were you responsible and safe with all your materials? Yes <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">15. Did you follow all my rules in the classroom? YES <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">16. Did you meet all the requirements for this assignment? YES <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">17. How is the Design Cycle important to the successful outcome of a project? It helps plan out a design before building it
