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: 20.8px;">Your bridge should be 5 - 6 inches high. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Your bridge should 4 - 5 inches wide. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Your bridge should hold at least 100 pounds. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">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? Triangular bridges are the strongest type of bridges. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">2.

<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. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">6. On your paper include why you think this bridge will hold the most weight.

Did you use all of the glue, popsicle sticks and other materials appropriately? <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Yes, we used all of them appropriately. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">8. Did you work with your group members appropriately? <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Grace and I worked appropriately. <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? <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Yes <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">10.

What would you do differently next time? <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">add more triangles <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">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: 20.8px;">we did well on investigate. We could improve on create. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">Investigate: <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">1.We found a lot of different ideas <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">2.
