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? <span style="color: #800080; font-family: Arial,Helvetica,sans-serif; font-size: 20.8px;">It depends. 4 of the generally stronger ones are: beam bridges, arch bridges, truss bridges, and suspension bridges. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">2. What bridge would work best for me? <span style="color: #800080; font-family: Arial,Helvetica,sans-serif; font-size: 20.8px;">A beam bridge. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">3. What geometric shape is the strongest structure? <span style="color: #800080; font-family: Arial,Helvetica,sans-serif; font-size: 20.8px;">A triangle. <span style="color: #0000ff; font-family: 'Arial Black',Gadget,sans-serif; font-size: 20.8px;">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. <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.
