POPSICLE STICK BRIDGE

Problem/Question
Problem- The problem is to build and design a bridge that spans 36 inches, a minimum of 5 inches wide, and a maximum of 6 inches tall, using only 200 popsicle sticks and unlimited Elmer's school glue. Also, to apply the steps of the engineering design process.
How are we going to do that?
-Decide what bridge to make.
-Discuss how we should create the bridge.
-Make a to scale model of our bridge.
-Construct the bridge carefully.

Types of Stress
Compression Stress- squeezed together, shoving until they move.
Tension Stress- pulling apart, tug-of-war.

Solutions To Deal With Stress
-Make sure that all the weight is distributed evenly.
-Make sure that there is an even amount of tension and compression.

What Bridge Did We Make?
We built a truss bridge because we don't have string/rope to build a suspension bridge, and bridges that are like platforms won't hold that much weight. Also, based on research, we found out that truss bridges are ideal for spanning short distances.
Materials Used
-150 regular popsicle sticks and 50 thin popsicle sticks
-unlimited Elmer's glue
-yard stick

How Much Weight Did Our Bridge Hold?
The bridge we made didn't really hold any weight. One end was loose and broke off when we put the weight on. Our bridge didn't hold any weights because, we didn't glue a part of it properly.
Advice For Fellow 6th Graders
Our advice for fellow 6th graders is to make sure that their bridge is properly glued together, so that part of the bridge won't break off when putting on the weight.

What Would You Do If You Got 200 More Popsicle Sticks? Why?
If we were given 200 more popsicle sticks we will add more trusses. Also, we will put more support on the top of the bridge so that the weight of the weights would be distributed evenly.
