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: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Suspension <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: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">One with a lot 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: #ff0000; 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: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">No <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: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">It has many triangles, and the more triangles the stronger the bridge is.

<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? <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Yes <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">8. Did you work with your group members appropriately? <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">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? <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Yes <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">10. Did your bridge hold 100 pounds? <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Yes <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">11. How much weight did your bridge hold? <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">258 <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">12. What would you do differently next time? <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Make a more secure base. <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. <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We investigated the strongest types of bridges and picked that one as our design. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We chose a bridge that has the more triangles, because triangles make the most secure structure. <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. <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We divided each day to work on one side. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2.<span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> We added the little but important things on the last day. <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. <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We used wood glue and hot glue to put the popsicle sticks together. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2.<span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> We tried to make everything perpendicular and even for a more secure structure. <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. <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We could've added more triangles to make an even more secure structure. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We could've used more glue to make the popsicle sticks connect better. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">14. Were you responsible and safe with all your materials? <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Yes <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">15.

How is the Design Cycle important to the successful outcome of a project? <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Y <span style="color: #ff0000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">ou have to investigate before you plan, plan before you create, and create before you evaluate. If you don't follow these steps correctly the outcome of your project wouldn't come out as well.
