Design Brief: (Day 2) Requirements: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">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: #f42f71; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">This question doesn't really have an answer. There is no exact answer because there are too many variables. <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: #f42f71; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">A symmetrical bridge with a flat surface in the shape of a rhombus. <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: #f42f71; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">A 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: #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? <span style="color: #aeff00; 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: #aeff00; 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: #aeff00; 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: #aeff00; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">no <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: #aeff00; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">85 pounds <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: #aeff00; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">make it square because those were the bridges that held. <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: #ff4400; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We did good on thinking about different bride types <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. <span style="color: #ff4400; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We didn't look up very many different 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. <span style="color: #ff4400; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We thought we had a great design. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. <span style="color: #ff4400; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We didn't consider the shape of the bridge <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: #ff4400; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">We worked hard to complete the bridge and got it done on time

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2.<span style="color: #ff4400; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;"> I stood on it before the smashing so I had to do a quick fix and then it didn't hold <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: #ff4400; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">I looked back on the bridge and thought about the shape and how we could improve it <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">2. <span style="color: #ff4400; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">I moped about it <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: #00ff95; 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? The design cycle can help us create a better product by allowing us to se step by step ideas we can follow.

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">18. What grade do you deserve on this unit? (1 - 6) a 5 or a 6 because we did every thing good but our bridge failed.

<span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">How you will be Graded: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Investigate = 10 points <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Plan = 10 points <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Create = 20 points <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Evaluate = 15 points <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">Completing all of the requirements = 40 points <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 17px;">5 points for being nice
