Design Brief: (Day 2) Requirements: Your bridge should cross over an index card. Your bridge should be 5 - 6 inches high. Your bridge should 4 - 5 inches wide. Your bridge should hold at least 100 pounds. You get one handful of popsicle sticks. <span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Questions: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">1. What is the strongest type of bridge? Beam Bridge 2. What bridge would work best for me? Truss Bridge 3. What geometric shape is the strongest structure? Triangle 4.

<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">PLAN: (1/2 Day) <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">5. Use a blank piece of paper to draw a rough draft of your bridge. 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: 20.8px;">CREATE: (4 DAYS) <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">7. Did you use all of the glue, popsicle sticks and other materials appropriately? Yes I did. 8. Did you work with your group members appropriately? Yes I did.

<span style="color: #800000; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">EVALUATION: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">9. Did you research bridge types? Yes. 10. Did your bridge hold 100 pounds? Yes. 11. How much weight did your bridge hold? 900 lbs. 12. What would you do differently next time? Nothing. 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!) I followed our plan pretty well. I could have followed it more closely. Investigate: 1. Find different bridges we could use. 2. Find out how sturdy they are. Plan: 1. Make a bridge with triangles. 2. Make it 5-6 in. tall. Create: 1. Glue the base. 2. Glue the area around it. Evaluate: 1. We got the bridge over 100 lbs. 2. We got it to be 5-6 in. 14. Were you responsible and safe with all your materials? Yes. 15. Did you follow all my rules in the classroom? Yes. 16. Did you meet all the requirements for this assignment? Yes. 17. How is the Design Cycle important to the successful outcome of a project? It can show how your product will be like. If you didn't use it, it probably wouldn't work.

How you will be Graded: Investigate = 10 points Plan = 10 points Create = 20 points Evaluate = 15 points Completing all of the requirements = 40 points 5 points for being nice

Total = 100 points <span style="display: block; font-family: arial,helvetica,sans-serif; font-size: 13px;"> <span style="display: block; font-family: arial,helvetica,sans-serif; font-size: 13px;"><span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Reagan has it on his wikispace.
