Transcript of Grade 9 Bridge Project

Grade 9 Bridge Project
The journey of a group of high school freshmen as they work to produce one of the world’s longest, strongest and lightest popsicle stick bridge.
Our Goal
As mentioned before, the goal of this project is to create one of the world’s longest, strongest and lightest popsicle bridge. With the help of our trusty teacher and our own knowledge, we hope to reach great potentials.
In a task like this, cooperation, responsibility, patience and teamwork are very important.
The Problem
We see bridges everyday in our lives ,but do we ever think about how to make them? For most of us, the answer is no.
While making this bridge, there was one big question in the minds of the fabricators: How in the world do we make this work?
To solve this , they used the help of their brains and the procedures sheet of course.
Journey To The Solution
The problems of building the bridge were cleared with not just one solution ,but many that were thought of and used as the process followed through. Thanks to the lessons by our teacher and our brains, the problems were solved. These lessons will be discussed in the next few slides.
Bridge Design
First of all, we have to know the load being put on the bridge, the key parts, the forces acting upon it, joints between parts and the symmetry.
Then, we have to ask ourselves certain questions like what are the weaknesses, or does the bridge have a standard gathering of parts?
Next, we will need to create a parts list of what will be needed.
Lastly we need to plan it all out and make decisions.
Dummies, Stringers and the Truss
Dummies are useful placeholders that are ½ of a popsicle stick and are put instead of the next stick to create an approximate distance.
Stringers are simply many popsicle sticks that overlap one another.
The truss is the result of the top stringer added with the bottom stringer and many isosceles triangles.

Many tools were required in order to build this bridge. They are as followed:
1. Popsicle sticks
2. Glue
3. Dummies
4. Binder Clips
5. Tie Members
6. Filers
7. Sandpapers
8. Trapezoid Templates
Safety comes first and that is why every member of this group was committed to ensure an unharmful working place for him or her and others.
An example was by always keeping the edges of tables clear of glue or materials so then anyone who walks by won't bump into anything.
Improvements for the Future
In order to have a well durability, the bridge should be made of thick wood and be made waterproof somehow.
To make it eco-friendly, we could try to use the wood from dead trees instead of cutting down new ones.
Painting the bridge with modern colours would definitely give it a better appearance.
Customer Satisfaction
Taking the opinions of customers in the design or appearance could help in creating something that they will like.
• Step: 1. Find information on bridges on the internet
• Step: 2. Analyze your research.
• Step: 3. Brainstorm bridge designs that you believe would accomplish the job properly.
• Step: 4. Pick the best design.
• Step: 5. Build it.
• Step: 6. Test it.
• Step: 7. Combine all the bridges together.
The objective of this class project is to teach students the value of teamwork and cooperation, so they can apply it to future careers.

This foot bridge structure is intended to hold anyone weighing 150 pounds on any part if its 9 foot unsupported span.

With this bridge, we hope to challenge other schools into building a longer, stronger and lighter popsicle stick bridge. This bridge will consist of many mini-bridges.
